Chapter 2: Product description
Product description
This chapter outlines the product, order codes, and specifications.
2.1 Product description
The G60 Generator Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based
relay that provides protection, monitoring, control, and recording functions for alternating current (AC) generators driven
by steam, gas, or hydraulic turbine. Current, voltage, and frequency protection are provided along with fault diagnostics.
Breaker fail function is provided for up to four breakers.
Voltage, current, and power metering are built into the relay as standard features. Current parameters are available as
total waveform root mean square (RMS) magnitude, or as fundamental frequency only RMS magnitude and angle (phasor).
Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of
storing up to 64 records with programmable trigger, content, and sampling rate, and data logger acquisition of up to 16
channels, with programmable content and sampling rate. The internal clock used for time-tagging can be synchronized
with an IRIG-B signal, using the Simple Network Time Protocol (SNTP) over the Ethernet port, or using the Precision Time
Protocol (PTP). This precise time stamping allows the sequence of events to be determined throughout the system. Events
can also be programmed (via FlexLogic™ equations) to trigger oscillography data capture that can be set to record the
measured parameters before and after the event for viewing on a computer PC. These tools significantly reduce
troubleshooting time and simplify report generation in the event of a system fault.
Several options are available for communication. An RS232 port (USB port with the graphical front panel) can be used to
connect to a computer to program settings and monitor actual values. The rear RS485 port allows independent access by
operating and engineering staff. It can be connected to system computers with baud rates up to 115.2 kbps. All serial ports
use the Modbus RTU protocol. The IEC 60870-5-103 protocol is supported on the RS485 interface. IEC 60870-5-103, DNP,
and Modbus cannot be enabled simultaneously on this interface. Also only one of the DNP, IEC 60870-5-103, and IEC
60870-5-104 protocols can be enabled at any time on the relay. When the IEC 60870-5-103 protocol is chosen, the RS485
port has a fixed even parity and the baud rate can be either 9.6 kbps or 19.2 kbps. The 100Base-FX or 100Base-TX Ethernet
interface provides fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, IEC 6185090-5, Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access to the relay via any
standard web browser (G60 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. The Ethernet
port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.
Secure Routable GOOSE (R-GOOSE) is supported with software options.
Settings and actual values can be accessed from the front panel or EnerVista software.
The G60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are
upgradable.

SECURITY
CHAPTER 2: PRODUCT DESCRIPTION
2.2 Security
The following security features are available:
2
•
Password security — Basic security present by default
•
EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The
feature is present by default in the EnerVista software.
•
CyberSentry security — Advanced security available using a software option. When purchased, the option is
automatically enabled, and the default Password security and EnerVista security are disabled.
2.2.0.1 EnerVista security
The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to
manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a
substation and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security
management system is disabled by default to allow the administrator direct access to the EnerVista software after
installation. It is recommended that security be enabled before placing the device in service.
Basic password or enhanced CyberSentry security applies, depending on purchase.
2.2.0.2 Password security
Password security is a basic security feature present by default.
Two levels of password security are provided: command and setting. Use of a password for each level controls whether all
users can enter commands and/or change settings.
Two types of connection security are provided: password entry from local or remote connection. Local access is defined as
any access to settings or commands via the front panel interface. This includes both keypad entry and the through a front
panel port. Remote access is defined as any access to settings or commands via any rear communications port. This
includes both Ethernet and RS485 connections. These two settings are on by default and apply to all users.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the G60, the remote password is used. If the
connection is to a front panel port, the local password applies. (These two local and remote password settings are not
shown in the figure.)
Password access events are logged in the Event Recorder.

CHAPTER 2: PRODUCT DESCRIPTION
SECURITY
2.2.0.3 CyberSentry security
CyberSentry security is available using software options that provide advanced security services. When an option is
purchased, the basic password security is disabled automatically.
CyberSentry provides security through the following features:
•
An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that is
centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standardsbased strong cryptography for authentication and credential protection
•
A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device
operations and configurations based on specific roles and individual user accounts configured on the AAA server (that
is, Administrator, Supervisor, Engineer, Operator, Observer roles)
•
Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM)
systems for centralized cybersecurity monitoring
•
Strong encryption of all access and configuration network messages between the EnerVista software and UR devices
using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter
Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the National
Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems
CyberSentry user roles
CyberSentry user roles (Administrator, Engineer, Operator, Supervisor, Observer) limit the levels of access to various UR
functions. This means that the EnerVista software allows for access to functionality based on the user’s logged in role.
Example: Administrative functions can be segmented from common operator functions, or engineering type access, all of
which are defined by separate roles so that access of UR devices by multiple personnel within a substation is allowed.
One role of one type is allowed to be logged in at a time. For example, one Operator can be logged in but not a second
Operator at the same time. This prevents subsets of settings from being changed at the same time.

CyberSentry user authentication
The following types of authentication are supported by CyberSentry to access the UR device:
•
Device Authentication (local UR device authenticates)
•
Server Authentication (RADIUS server authenticates)
The EnerVista software allows access to functionality that is determined by the user role, which comes either from the local
UR device or the RADIUS server.
The EnerVista software has a device authentication option on the login screen for accessing the UR device. When the
"Device" button is selected, the UR uses its local authentication database and not the RADIUS server to authenticate the
user. In this case, it uses its built-in roles (Administrator, Engineer, Supervisor, Observer, Operator, or Administrator and
Supervisor when Device Authentication is disabled) as login names and the associated passwords are stored on the UR
device. As such, when using the local accounts, access is not user-attributable.
In cases where user-attributable access is required especially to facilitate auditable processes for compliance reasons, use
RADIUS authentication.
When the "Server" Authentication Type option is selected, the UR uses the RADIUS server and not its local authentication
database to authenticate the user.
No password or security information is displayed in plain text by the EnerVista software or UR device, nor is such
information ever transmitted without cryptographic protection.
CyberSentry server authentication
The UR has been designed to direct automatically the authentication requests based on user names. In this respect, local
account names on the UR are considered as reserved and not used on a RADIUS server.
The UR detects automatically whether an authentication request is to be handled remotely or locally. As there are five local
accounts possible on the UR, if the user ID credential does not match one of the five local accounts, the UR forwards
automatically the request to a RADIUS server when one is provided.

ORDER CODES
CHAPTER 2: PRODUCT DESCRIPTION
If a RADIUS server is provided, but is unreachable over the network, server authentication requests are denied. In this
situation, use local UR accounts to gain access to the UR system.
2.3 Order codes
2
The order code is on the product label and indicates the product options applicable.
The G60 is available as a 19-inch rack horizontal mount or reduced-size (¾) vertical unit. It consists of the following
modules: power supply, CPU, CT/VT, contact input and output, transducer input and output, and inter-relay
communications. Module options are specified at the time of ordering.
The order codes shown here are subject to change without notice. See the web page for the product for the latest options.
The order code depends on the mounting option (horizontal or vertical) and the type of CT/VT modules (enhanced
diagnostic CT/VT modules or HardFiberTM process bus module). The process bus module provides an interface to
HardFiber Bricks.
The R-GOOSE protocol described in IEC 61850-8-1 is available through the IEC 61850 software option. R-GOOSE
security requires the CyberSentry software option.
For Japanese, the settings display in Japanese on the graphical front panel, while the keys printed on the panel are
in English.

2.4 Signal processing
2.4.1 UR signal processing
The UR series relays are microprocessor-based protective relays that are designed to measure power system conditions
directly via CT and VT inputs and via other sources of information, such as analog inputs, communications inputs, and
contact inputs. The following figure shows the overall signal processing in URs.
An analog low pass anti-aliasing filter with a 3 dB corner frequency is set at 2.4 kHz and is used for current and voltage
analog filtering as well as signal conditioning. The same filtering is applied for phase, ground currents, phase-to-phase
(when applicable), and auxiliary voltages. The 2.4 kHz cut-off frequency applies to both 50 Hz and 60 Hz applications and
fixed in the hardware, and thus is not dependent on the system nominal frequency setting.

SIGNAL PROCESSING
CHAPTER 2: PRODUCT DESCRIPTION
Figure 2-4: UR signal processing
2
The UR samples its AC signals at 64 samples per cycle, that is, at 3840 Hz in 60 Hz systems, and 3200 Hz in 50 Hz systems.
The sampling rate is dynamically adjusted to the actual system frequency by an accurate and fast frequency tracking
system.
The analog/digital converter has the following ranges of AC signals:
Voltages:
Eq. 2-1
Currents:
Eq. 2-2
Current harmonics are estimated based on raw samples with the use of the full-cycle Fourier filter. Harmonics 2nd through
25th are estimated.
2-18
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 2: PRODUCT DESCRIPTION
SPECIFICATIONS
True RMS value for the current is calculated on a per-phase basis. The true RMS can be used for demand recording or as an
input signal to Time Overcurrent function, if the latter is intended for thermal protection. The true RMS is calculated as per
the widely accepted definition:
Eq. 2-3
RMS values include harmonics, inter-harmonics, DC components, and so on, along with fundamental frequency values.
The true RMS value reflects thermal effects of the current and is used for the thermal related monitoring and protection
functions.
Protection and control functions respond to phasors of the fundamental and/or harmonic frequency components
(magnitudes and angles), with an exception for some functions that have an option for RMS or fundamental
measurements, or some function responding to RMS only. This type of response is explained typically in each element's
section in this instruction manual.
Currents are pre-filtered using a Finite Impulse Response (FIR) digital filter. The filter is designed to reject DC components
and low-frequency distortions, without amplifying high-frequency noise. This filter is referred to as a modified MIMIC filter,
which provides excellent filtering and overall balance between speed and accuracy of filtering. The filter is cascaded with
the full-cycle Fourier filter for the current phasor estimation.
Voltages are pre-filtered using a patented Finite Impulse Response (FIR) digital filter. The filter has been optimized to reject
voltage-transformer-specific distortions, such as Capacitive Voltage Transformer (CVT) noise and high-frequency
oscillatory components. The filter is cascaded with the half-cycle Fourier filter for the voltage phasor estimation.
The URs measure power system frequency using the Clarke transformation by estimating the period of the waveform from
two consecutive zero-crossings in the same direction (negative-to-positive). Voltage or current samples are pre-filtered
using a Finite Impulse Response (FIR) digital filter to remove high frequency noise contained in the signal. The period is
used after several security conditions are met, such as true RMS signal must be above 6% nominal for a certain time. If
these security conditions are not met, the last valid measurement is used for a specific time after which the UR reverts to
nominal system frequency.
Synchrophasors are calculated using a patented convolution integral algorithm. This algorithm allows use of the same
time-stamped samples, which are used for protection and taken at the same sampling frequency. This allows URs to use
one sampling clock for both protection algorithms and synchrophasors.
Synchrophasors on firmware versions 7.23 and up have been tested and certified to meet IEEE C37.118-2011 and
C37.118.1a-2014 standards for both metering and protection classes with outputs available up to 60 synchrophasors per
second for the metering class and 120 synchrophasors per second for the protection class. Synchrophasors measurement
is also available via IEC 61850-90-5 protocol.
The contact inputs threshold is settable in the firmware with 17, 33, 84, 166 V DC settings available. Inputs are scanned
every 0.5 ms and can be conditioned for the critical applications, using debounce time timer, settable from 0.0 to 16.0 ms.
Contact inputs with auto-burnishing are available as well, when external contacts are exposed to the contamination in a
harsh industrial environment.
All measured values are available in the UR metering section on the front panel and via communications protocols.
Measured analog values and binary signals can be captured in COMTRADE format with sampling rates from 8 to 64
samples per power cycle. Analog values can be captured with the Data Logger, allowing much slower rates extended over
a long period of time.
Other advanced UR order code options are available to support IEC 61850 Ed2.0 (including fast GOOSE, MMS server, 61850
services, ICD/CID/IID files, and so on), IEEE 1588 (IEEE C37.238 power profile) based time synchronization, CyberSentry
(advanced cyber security), the Parallel Redundancy Protocol (PRP), IEC 60870-5-103, and so on.

The operating times include the activation time of a trip rated form-A output contact unless otherwise indicated. FlexLogic
operands of a given element are 4 ms faster. Take this into account when using FlexLogic to interconnect with other
protection or control elements of the relay, building FlexLogic equations, or interfacing with other intelligent electronic
devices (IEDs) or power system devices via communications or different output contacts. If not specified, the operate times
given here are for a 60 Hz system at nominal system frequency. Operate times for a 50 Hz system are 1.2 times longer.
Timer Accuracy is specified as a percentage of the total operating time that is the sum of the Operate Time and settable
Pickup Delay.

3.2.1 Horizontal units
The G60 is available as a 19-inch rack horizontal mount unit with a removable front panel. The front panel is specified as
enhanced, basic, or graphical at the time of ordering. The enhanced and graphical front panels contain additional userprogrammable pushbuttons and LED indicators.
The modular design allows the relay to be upgraded and repaired by qualified service personnel. The front panel is hinged
to allow access to the modules. The front panel is itself removable to allow mounting on doors with limited rear depth and
for upgrading.
In November 2017, GE began transitioning to Rev. 2 of the enhanced horizontal front panel. This panel can be identified by
the use of a screw instead of a knob to close the panel. It can conform to an IP54 rating with the IP54 mounting collar
purchased separately. The IP54 mounting collar can be used in panel-mount installations, not 19-inch rack-mount
installations. The IP54 mounting collar cannot be used with Rev. 1 enhanced front panels.
The case dimensions are shown in the following figures, along with panel cutout details for panel mounting. When
planning the location of your panel cutout, ensure that provision is made for the front panel to swing open without
interference to or from adjacent equipment.
The relay must be mounted such that the front panel sits semi-flush with the panel or switchgear door, allowing the
operator access to the keypad and the front communications port.

3.2.3 Rear terminal layout
3
Do not touch any rear terminals while the relay is energized, else death or serious injury can
result from electrical shock.
Small form-factor pluggable ports (SFPs) are pluggable transceivers. They transmit, receive, and
convert electrical signals to optical signals and vice-versa. They are inserted into the Ethernet ports
on the CPU module. A photo in the Maintenance chapter shows this plug-in device. Do not use nonvalidated transceivers or install validated transceivers in the wrong Ethernet slot, else damage can
occur.
The relay follows a convention for terminal number assignments, which are three characters long and assigned by module
slot position, row number, and column letter. Two-slot wide modules take their slot designation from the first slot position
(nearest to CPU module), indicated by an arrow on the terminal block. The figure shows an example of rear terminal
assignments.

The torque used to connect the screws that connect the terminal blocks (top screws a, b, c) and the metal plates over
empty slots to the chassis is 9 inch-pounds. For the screws used to wire the terminal blocks (rows 1 to 8), use 19±1 inchpounds. During manufacturing, the power supply and CPU modules are installed in slots B and D of the chassis with 13
inch-pounds of torque on the screws at the top and bottom of the modules. Wire connections to these two modules at 13

Filter networks and transient protection clamps are used in the hardware to prevent damage caused
by high peak voltage transients, radio frequency interference (RFI), and electromagnetic interference
(EMI). These protective components can be damaged by application of the ANSI/IEEE C37.90
specified test voltage for longer than the specified minute.
3.3.3 Control power
Power supplied to the relay must be connected to the matching power supply range of the relay. If
incorrect voltage is applied or voltage is applied to the wrong terminals, damage can occur.
The G60, like almost all electronic relays, contains electrolytic capacitors. These capacitors are wellknown to deteriorate over time if voltage is not applied periodically. Deterioration can be avoided by
powering up the relay at least once a year.
The power supply module can be ordered for two possible voltage ranges, and the G60 can be ordered with or without a
redundant power supply module option. Each range has a dedicated input connection for proper operation. The ranges
are as follows (see the Specifications section of chapter 2 for details):
•
Low (LO) range — 24 to 48 V (DC only) nominal
•
High (HI) range — 125 to 250 V nominal
The power supply module provides power to the relay and supplies power for dry contact input connections.
The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the
Typical Wiring Diagram earlier). The critical failure relay is a form-C device that is energized once control power is applied
and the relay has successfully booted up with no critical self-test failures. If ongoing self-test diagnostic checks detect a
critical failure (see the Self-Test Errors section in chapter 7) or control power is lost, the relay de-energizes.
To connect power to the relay, 14 gauge stranded wire with disconnect devices is recommended. Connect all wires to the
relay before turning on power.
For high-reliability systems, the G60 has a redundant option in which two G60 power supplies are placed in parallel on the
bus. If one of the power supplies becomes faulted, the second power supply assumes the full load of the relay without any
interruptions. Each power supply has a green LED on the front of the module to indicate that it is functional. The critical fail
relay of the module also indicates a faulted power supply.
An LED on the front of the control power module shows the status of the power supply, as outlined in the table.

3.3.3.1 Non-volatile data storage
Non-volatile data is temporary data required after a power cycle for relay state, such as latch status before reboot. The
relay saves this data in non-volatile storage every two minutes or when a state change occurs.
If a state change occurs just before a power down (less than two minutes) and the relay power is cycled, some temporary
data can be saved and the prior state is retained at power up. Otherwise, a two-minute powered on period after a state
change ensures that all temporary state changes required after reboot have been saved. A command also is available to
initiate saving of data in the compact flash memory using Commands > Relay Maintenance > Save Volatile Data.
3.3.4 CT/VT modules
The CT and VT inputs are analog current transformer and voltage transformer signals used to monitor AC power lines. The
UR-series relays support 1 A and 5 A CTs.
A CT/VT module can have current or voltage inputs on channels 1 through 4 inclusive, or channels 5 through 8 inclusive.
Channels 1 and 5 are intended for connection to phase A, and are labelled as such in the relay. Likewise, channels 2 and 6
are intended for connection to phase B, and channels 3 and 7 are intended for connection to phase C.
Channels 4 and 8 are intended for connection to a single-phase source. For voltage inputs, these channels are labelled as
auxiliary voltage (VX). For current inputs, these channels are intended for connection to a CT between system neutral and
ground, and are labelled as ground current (IG).
Verify that the connection made to the relay terminals for nominal current of 1 A or 5 A matches the
secondary rating of the connected CTs. Unmatched CTs can result in equipment damage or
inadequate protection.
To connect to the module, size 12 American Wire Gauge (AWG) is used commonly; the maximum size is 10 AWG.

WIRING
CHAPTER 3: INSTALLATION
CT/VT modules can be ordered with a standard ground current input that is the same as the phase current input. Each AC
current input has an isolating transformer and an automatic shorting mechanism that shorts the input when the module is
withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1
to 50000 A primaries and 1 A or 5 A secondaries can be used.
CT/VT modules with a sensitive ground input are also available. The ground CT input of the sensitive ground modules is 10
times more sensitive than the ground CT input of standard CT/VT modules. However, the phase CT inputs and phase VT
inputs are the same as those of regular CT/VT modules.
These modules have enhanced diagnostics that can automatically detect CT/VT hardware failure and take the relay out of
service.
CT connections for both ABC and ACB phase rotations are identical, as shown in the Typical Wiring Diagram.

The exact placement of a zero-sequence core balance CT to detect ground fault current is shown as follows. Twisted-pair
cabling on the zero-sequence CT is recommended.

The phase voltage channels are used for most metering and protection purposes. The auxiliary voltage channel is used as
input for the synchrocheck and volts-per-hertz features, which are optional features for some UR models.

3.3.5 Process bus modules
The G60 can be ordered with a process bus interface module. The module interfaces with the HardFiber Process Bus
System, or HardFiber Brick, allowing bidirectional IEC 61850 fiber-optic communications with up to eight HardFiber Bricks.
The HardFiber system integrates seamlessly with the existing UR-series applications, including protection functions,
FlexLogic, metering, and communications.
This process bus system offers the following benefits:
•
Reduces labor associated with design, installation, and testing of protection and control applications using the UR by
reducing the number of individual copper terminations
•
Integrates seamlessly with existing UR applications, since the IEC 61850 process bus interface module replaces the
traditional CT/VT modules
•
Communicates using open standard IEC 61850 messaging
For details on the HardFiber system, see its Instruction Manual.
3.3.6 Contact inputs and outputs
Nearly all contact input/output modules have 24 terminal connections. The connections are arranged typically as three
terminals per row, with eight rows in total. A given row of three terminals can be used for the outputs of one relay. For
example, for form-C relay outputs, the terminals connect to the normally open (NO), normally closed (NC), and common
contacts of the relay. For a form-A output, there are options of using current or voltage detection for feature supervision,
depending on the module ordered. The terminal configuration for contact inputs is different for the two applications.
The contact inputs are grouped with a common return. The input/output modules have three versions of grouping: four
inputs per common return, five inputs per common return on a high-density module, and two inputs per common return.
When a contact input/output module is ordered, four inputs per common is used. If the inputs must be isolated per row,
then two inputs per common return are selected (4D module). If the space limitation in the relay requires use of a highdensity input module (6W), five inputs share one common return and the module has six banks of inputs.
The tables and diagrams that follow illustrate the module types (6A and so on) and contact arrangements that can be
ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot
position and row number. However, since there are two contact inputs per row, these names are assigned by module slot
position, row number, and column position.

CHAPTER 3: INSTALLATION
Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is
open, and the DC current through the output contact when it is closed. Each of the monitors contains a level detector
whose output is set to logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is
set to “On = 1” when there is a voltage across open contact (the detector allows a current of about 1 to 2.5 mA), and the
current monitor is set to “On = 1” when the current flowing through the closed contact exceeds about 80 to 100 mA. The
voltage monitor is intended to check the health of the overall trip circuit, and the current monitor can be used to seal-in the
output contact until an external contact has interrupted current flow. If enabled, the current monitoring can be used as a
seal-in signal to ensure that the form-A contact does not attempt to break the energized inductive coil circuit and weld the
output contacts.
3
Block diagrams are shown as follows for form-A and solid-state relay outputs with optional voltage monitor, optional
current monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact
outputs. Form-A contact output with or without a current or voltage monitoring option is not polarity sensitive. The polarity
shown in the figure is required for solid-state contact output connection.
Figure 3-19: Form-A and solid-state contact outputs with voltage and current monitoring
The operation of voltage and current monitors is reflected with the corresponding FlexLogic operands (CONT OP # VON, CONT
OP # VOFF, and CONT OP # ION) that can be used in protection, control, and alarm logic. The typical application of the voltage
monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the control
command.
See the Digital Elements section of chapter 5 for an example of how form-A and solid-state relay contacts can be applied
for breaker trip circuit integrity monitoring.
Consider relay contacts unsafe to touch when the unit is energized. Death or serious injury can
result from touching live relay contacts.

USE OF FORM-A AND SOLID-STATE RELAY OUTPUTS IN HIGH-IMPEDANCE CIRCUITS
For form-A and solid-state relay output contacts internally equipped with a voltage measuring circuit across the
contact, the circuit has an impedance that can cause a problem when used in conjunction with external high-input
impedance monitoring equipment, such as modern relay test set trigger circuits. These monitoring circuits can
continue to read the form-A contact as being closed after it has closed and subsequently opened, when measured
as an impedance.
The solution is to use the voltage measuring trigger input of the relay test set, and connect the form-A contact
through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power supply is used as a
source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across either the form-A contact or
the resistor can be used to monitor the state of the output.
Where a tilde “~” symbol appears, substitute the slot position of the module. Where a number sign “#” appears,
substitute the contact number.
When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, give the
FlexLogic operand driving the contact output a reset delay of 10 ms to prevent damage of the output
contact (in situations when the element initiating the contact output is bouncing, at values in the
region of the pickup value).
For high-density input/output modules 6W and 6X, use the following guidelines to connect. The new I/O modules use pin
type terminal blocks instead of the current ring type. The new terminals are required to achieve higher I/O count per
module.
•
12 to 24 AWG (3.3 mm2 to 0.2 mm2), single wire termination
•
16 to 24 AWG (1.31 mm2 to 0.2 mm2), multiple wire termination with matching wire sizes and stranding. Two wires
maximum per circuit.
•
Suggested wiring screw tightening torque is a minimum 4.43 in-lb (0.5 Nm) and maximum 5.31 in-lb (0.6 Nm)
•
Minimum suggested temperature rating for the conductors is 75°C

For proper functionality, observe the polarity shown in the figures for all contact input and output
connections.
3.3.6.1 Contact inputs
A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail supplied by the power
supply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input
group has its own common (negative) terminal that must be connected to the DC negative terminal (B3a) of the power
supply module. When a dry contact closes, a current of 1 to 3 mA flows through the associated circuit.
A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this
contact is connected to the required contact input terminal. If a wet contact is used, then the negative side of the external
source must be connected to the relay common (negative) terminal of each contact group. The maximum external source
voltage for this arrangement is 300 V DC.
The voltage threshold at which each group of four contact inputs detects a closed contact input is programmable as
17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources.

There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We recommend
using an external DC supply.
3.3.6.2 General application considerations
Contacts outputs of protective relays, auxiliary contacts from breakers, disconnectors and other devices are connected
generally to contacts inputs of protective relays. In some situations, the contact outputs of some protective relays can
have high impedance connected across it. When such a contact output is connected across a G60 contact input, it can
spuriously operate the G60 input even when the output is open, if there is a substantial distributed capacitance
(represented by C1) present in the wiring between the output and the G60 input, and the debounce time setting in the G60
relay is low enough. This false assertion of the contact input, when there is inadvertent ground present at the DC positive
terminal, can be prevented by inserting a resistor across the G60 input.
The following figure shows a typical DC circuit, with battery ground detection, of contact input. The contact output has
parallel impedance across it (represented by R1).
Figure 3-24: Typical contact input DC circuit
The presence of the impedance path (R1) across the contact output allows the stray (distributed) capacitance C1 to charge
as shown, thus developing a voltage across the contact input enough to momentarily operate the input while the
capacitance discharges in the presence of DC ground on the positive terminal of the battery.
The duration of the discharge depends on the value of the distributed capacitance, the initial voltage of the distributed
capacitance, and the input impedance of the contact input. If the duration is greater than the debounce time setting, then
the contact input operates.
The application example that follows describes how to mitigate this issue by connecting a resistor across the contact
input, as shown in the next figure, or by adjusting the debounce time setting to a value greater than the discharge time to
prevent spurious operation of the contact input only if the voltage (with output open) across the contact input due to trickle
current is less than the threshold voltage. This operation of contact inputs also can be prevented by using the Auto-Burnish
contact inputs or contact inputs with active impedance.

Application example
This example is for illustrative purposes only and the calculations present the worst-case scenario. In practice, the value of
debounce time can be lower.
Contact input ON state impedance used in the calculation of the discharge period is based on the following table.
Table 3-4: Discharge period
Battery voltage (V)
Input impedance (kΩ)
130
50
250
97
Debounce time setting = 2 ms
Assume a stray capacitance of 0.1 μF.
Assume an initial voltage across the stray capacitance "Vinitial" = 19 V (Vthreshold - 65 V), where Vthreshold = 84 V. The
initial voltage Vinitial depends on values of impedance of R1 and contact inputs when the contact input is OFF (nonactivated state).
Therefore, discharge time constant (τ) =50 kΩ *0.1 μF = 5 ms.
Discharge period t is calculated from the following equation:
Vthreshold = (Vbatt - VInitial) *e^ (-t/τ)
84 = -149 *e^ (t/0.005)
Eq. 3-1
T = -0.005 * ln (84/149) = 0.0029 s
Therefore, in this example the contact inputs operate.
To prevent this operation, the debounce time must be increased to 4 ms (set debounce time as per the following table) or
insert a resistor less than or equal to "R" as calculated later.

* Default debounce time on contact inputs is 6 ms.
The value of this resistor "R" is calculated as follows:
1.
Determine the minimum voltage (V threshold) required to turn on the input. This is determined by direct measurement
or referenced in the input specifications.
2.
Calculate the resistance necessary to limit the voltage to 1/3 V threshold (when the contact is OFF, the non-activated
state) as follows:
R = (Vthreshold / 3) / (2 mA)
Eq. 3-2
The 2 mA current is used in case the contact input is connected across the GE Form A contact output with voltage
monitoring. Otherwise use the amperage of the active circuit connected to the contact input when its contact output
is open and the voltage across the contact input is third trigger threshold to calculate the resistor value.
3.
When the contact is ON (operate state), the battery voltage appears across the resistor. The wattage rating of the
resistor is then:
4.
Applying the following equation to our example:
PR = 1.3 * (Vbatt) ^2 / R Watts
Eq. 3-3
R = 84 V / 3 * (1 / 2 mA) = 14 kΩ
PR = 1.57 Watts
5.
Eq. 3-4
Calculating the voltage across the contact input with the Burden Resistor, Voltage across the contact Input:
Vresistor = 2 mA * 14 Kohm = 28 V
Vresistor < contact input threshold (84 V)
Eq. 3-5
In conclusion, in this example, the contact input does NOT operate falsely with the Burden Resistor across its input AND
when a battery ground is present.
3.3.6.3 Use of contact inputs with auto-burnishing
The contact inputs sense a change of state of the external device contact based on the measured current. When external
devices are located in a harsh industrial environment (either outdoor or indoor), their contacts can be exposed to various
types of contamination. Normally, there is a thin film of insulating sulfidation, oxidation, or contaminates on the surface of
the contacts, sometimes making it difficult or impossible to detect a change of state. This film must be removed to
establish circuit continuity — an impulse of higher than normal current can accomplish this.
The contact inputs with auto-burnish create a high current impulse when the threshold is reached to burn off this oxidation
layer as a maintenance to the contacts. Afterwards the contact input current is reduced to a steady-state current. The
impulse has a five-second delay after a contact input changes state.
Figure 3-26: Current through contact inputs with auto-burnishing
Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with
auto-burnishing allow currents up to 50 to 70 mA at the first instance when the change of state is sensed. Then, within 25
to 50 ms, this current is slowly reduced to 3 mA as indicated. The 50 to 70 mA peak current burns any film on the contacts,
allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing starts when
external device contact bouncing is over.
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
3-29

WIRING
CHAPTER 3: INSTALLATION
Another important difference between the auto-burnishing input module and the regular input modules is that only two
contact inputs have common ground, as opposed to four contact inputs sharing one common ground (see the Contact
Input and Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources.
Consequently, the threshold voltage setting is also defined per group of two contact inputs.
The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP
switch for each contact, for a total of 16 inputs.
Figure 3-27: Auto-burnish DIP switches
3
The auto-burnish circuitry has an internal fuse for safety purposes. During regular maintenance, check the auto-burnish
functionality using an oscilloscope.
3.3.6.4 Use of contact inputs with active impedance
Contact inputs can be susceptible to parasitic capacitance, caused by long cable runs affected by switching surges from
external circuits. This can result in inadvertent activation of contact inputs with the external contact open. In this case, GE
recommends using the contact I/O module with active impedance circuit.
Active impedance contact input can tolerate external cable capacitance of up to 0.2 µF, without entering the ON state for
more than 2 ms. The contact input debounce time can still be set above 2 ms for added security to prevent contact input
activations caused by external transient ON states.
An active impedance contact input is normally in Low impedance mode during OFF contact state (non-activated
condition). During Low impedance state, contact input impedance is maintained at 10 K Ohms impedance to allow fast
discharge of the stray capacitance of the long cables.
When the contact input voltage exceeds the set threshold, active impedance maintains 10 K Ohms impedance. If voltage
starts rapidly decreasing, this indicates that stray capacitance is being discharged through the contact input. If, however,
voltage stabilizes above the set threshold, the input impedance is switched to High impedance mode of 100 K Ohms. This
value reduces the input current to <3 mA, and contact input switches to the ON state (operated state).
The figure shows the active impedance contact input V-I characteristic. Different thresholds with their corresponding
characteristics are shown by color. The contact input is in the ON (operated) state if the input voltage is to the right of the
colored threshold band (+/-10% tolerance), and the contact input is in the OFF (non-activated) state when input voltage is
to the left of the band. A contact input is in LOW state during non-operated system condition, and actively switches to
HIGH state upon detection of input voltage above the settable threshold.

3.3.7 Transducer inputs and outputs
Transducer input modules receive input signals from external DCmA output transducers (DCmA In) or resistance
temperature detectors (RTDs). Hardware and software are provided to receive signals from these external transducers and
convert these signals into a digital format for use as required.
Transducer output modules provide DC current outputs in several standard DCmA ranges. Software is provided to
configure virtually any analog quantity used in the relay to drive the analog outputs.
Each transducer input/output module has 24 terminal connections. These connections are arranged as three terminals per
row over eight rows. A given row can be used for either inputs or outputs, with terminals in column "a" having positive
polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/output channel,
the name of the channel is assigned using the module slot position and row number.
Each module also requires that a connection from an external ground bus be made to terminal 8b. The current outputs
require a twisted-pair shielded cable, where the shield is grounded at one end only. The following figure illustrates the
transducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that can be ordered for the relay.
Where a tilde “~” symbol appears, substitute the slot position of the module.

3.3.9.2 RS485 port
RS485 data transmission and reception are accomplished over a single twisted-pair wire with transmit and receive data
alternating over the same two wires. Through the use of the port, continuous monitoring and control from a remote
computer, SCADA system, or Power Line Carrier (PLC) is possible.
To minimize errors from noise, the use of shielded twisted-pair wire is recommended. Correct polarity must be observed.
For instance, the relays must be connected with all RS485 “+” terminals connected together, and all RS485 “–” terminals
connected together. Though data is transmitted over a two-wire twisted pair, all RS485 devices require a shared reference,
or common voltage. This common voltage is implied to be a power supply common. Some systems allow the shield (drain
wire) to be used as common wire and to connect directly to the G60 COM terminal (#3); others function correctly only if the
common wire is connected to the G60 COM terminal, but insulated from the shield.
To avoid loop currents, ground the shield at only one point. If other system considerations require the shield to be
grounded at more than one point, install resistors (typically 100 ohms) between the shield and ground at each grounding
point. Each relay needs to be daisy-chained to the next one in the link. A maximum of 32 relays can be connected in this
manner without exceeding driver capability. For larger systems, additional serial channels must be added. It is also
possible to use commercially available repeaters to have more than 32 relays on a single channel. Avoid star or stub
connections entirely.

Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the
communication link. For this reason, surge protection devices are provided internally at both communication ports. An
isolated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum
reliability, ensure that all equipment has similar transient protection devices installed.
Terminate both ends of the RS485 circuit with an impedance as shown in the figure.

3.3.9.3 100Base-FX fiber optic ports
The fiber-optic communication ports allow for fast and efficient communications between relays at 100 Mbps. Optical
fiber can be connected to the relay supporting a wavelength of 1310 nm in multimode.
Ensure that the dust covers are installed when the fiber is not in use. Dirty or scratched connectors can lead to high losses
on a fiber link.
3.3.10 IRIG-B
There is a round IRIG-B connector at the back of the CPU module, marked "IN". Use is optional.
IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The
IRIG-B code allows time accuracies of up to 100 ns. The GE MultiSync 100 1588 GPS Clock as well as third-party equipment
are available for generating the IRIG-B signal. This equipment can use a global positioning system (GPS) satellite system to
obtain the time reference so that devices at different geographic locations can be synchronized. The IRIG time code
formats are serial, pulse width-modulated codes that can be either DC level shifted or amplitude modulated (AM). Using
IRIG-B input, the G60 operates an internal oscillator with 1 µs resolution and accuracy.

Using an amplitude-modulated receiver causes errors up to 1 ms in event time stamping.
When IRIG-B is used as the time synchronization source for synchrophasors, the DC level shifted option must be
used in order to achieve the 1% Total Vector Error specified by the standard. If amplitude modulated IRIG-B is used,
it results in a 20 to 25 degree error in the synchrophasor angle measurement. The IEEE 1588 Precision Time
Protocol can also be used to achieve accurate time synchronization for synchrophasor calculation.
3.4 Direct input and output communications
3.4.1 Description
The direct inputs and outputs feature makes use of the type 7 series of communications modules and allows direct
messaging between UR devices. The communications modules are outlined in the table later in this section.
The communications channels are normally connected in a ring configuration, as shown in the following figure. The
transmitter of one module is connected to the receiver of the next module. The transmitter of this second module is then
connected to the receiver of the next module in the ring. This is continued to form a communications ring. The figure
illustrates a ring of four UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to
UR4-Rx, and UR4-Tx to UR1-Rx. A maximum of 16 URs can be connected in a single ring.

DIRECT INPUT AND OUTPUT COMMUNICATIONS

Inter-relay communication (IRC) modules with protocol C37.94 and G.703 are designed for back-to-back communication
connections, so the ring configuration shown in the previous figure does not apply. To establish inter-relay communication
in more than two URs, you need to have a two-channel IRC module and enable the DIRECT I/O CHANNEL CROSSOVER setting
in all relays, as shown in the next figure. This configuration can be expanded to 16 URs, and this configuration does not
provide a redundancy ring since both channels are made into a single ring by the channel crossover function. As per the
figure entitled Typical Pin Interconnection between Two G.703 Interfaces later in this chapter, the clock is supplied typically
by multiplexer (MUX) and all URs are in Loop Timing Mode. If there is no MUX, then UR1 and UR3 can be in Internal Timing
Mode and UR2 and UR4 can be in Loop Timing Mode. That is, connected channels must have opposite timing modes.

G.703 is an International Telecommunications Union (ITU) standard for the transmission of data and voice signals. Modules
7R (one channel) and 7S (two channels) apply.

AWG 24 twisted shielded pair wiring is recommended for external connections, with the shield grounded only at one end.
Connecting the shield to pin X1a or X6a grounds the shield since these pins are connected internally to ground. Thus, if
pin X1a or X6a is used to ground the shield at one end, do not ground the shield at the other end. This interface module is
protected by surge suppression devices.

Pin nomenclature differs from one manufacturer to another. It is not uncommon to see pinouts numbered TxA, TxB,

1.
With the power to the relay off, remove the G.703 module (7R or 7S) as follows. Record the original location of the
module to help ensure that the same or replacement module is inserted into the correct slot.
2.
Simultaneously pull the ejector/inserter clips located at the top and at the bottom of each module in order to release
the module for removal. (For more information on accessing modules, see the Maintenance chapter.)
3.
Remove the module cover screw.
4.
Remove the top cover by sliding it towards the rear and then lift it upwards.

Re-insert the G.703 module. Take care to ensure that the correct module type is inserted into the correct slot position.
The ejector/inserter clips located at the top and bottom of each module must be in the disengaged position as the
module is inserted smoothly into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips
simultaneously. When the clips have locked into position, the module is inserted fully.

timing mode for back-to-back (UR-to-UR) connections. For back-to-back connections, set octet timing (S1 = OFF) and
timing mode to internal timing (S5 = ON and S6 = OFF).
•
Loop Timing Mode — The system clock is derived from the received line signal. Therefore, set the G.703 timing
selection to loop timing mode for connections to higher order systems. For connection to a higher order system (URto-multiplexer, factory defaults), set to octet timing (S1 = ON) and set timing mode to loop timing (S5 = OFF and S6 =

In minimum remote loopback mode, the multiplexer is enabled to return the data from the external interface without any
processing to assist in diagnosing G.703 line-side problems irrespective of clock rate. Data enters from the G.703 inputs,
passes through the data stabilization latch that also restores the proper signal polarity, passes through the multiplexer,
and then returns to the transmitter. The differential received data is processed and passed to the G.703 transmitter module
after which point the data is discarded. The G.703 receiver module is fully functional and continues to process data and
passes it to the differential Manchester transmitter module. Since timing is returned as it is received, the timing source is
expected to be from the G.703 line side of the interface.
Figure 3-47: G.703 minimum remote loopback mode
In dual loopback mode, the multiplexers are active and the functions of the circuit are divided into two with each receiver/
transmitter pair linked together to deconstruct and then reconstruct their respective signals. Differential Manchester data
enters the Differential Manchester receiver module and then is returned to the differential Manchester transmitter module.
Likewise, G.703 data enters the G.703 receiver module and is passed through to the G.703 transmitter module to be
returned as G.703 data. Because of the complete split in the communications path and because, in each case, the clocks
are extracted and reconstructed with the outgoing data, in this mode there must be two independent sources of timing.
One source lies on the G.703 line side of the interface while the other lies on the differential Manchester side of the
interface.

There are two RS422 inter-relay communications modules available: single-channel (module 7T) and dual-channel (module

recommended for external connections. These modules are protected by optically-isolated surge suppression devices.
The shield pins (6a and 7b) are connected internally to the ground pin (8a). Proper shield termination is as follows:
•
Site 1 — Terminate shield to pins 6a or 7b or both
•
Site 2 — Terminate shield to COM pin 2b
Match the clock terminating impedance with the impedance of the line.

3.4.5.2 Two-channel application via multiplexers
The RS422 interface can be used for single-channel or two-channel applications over SONET/SDH or multiplexed systems.
When used in single-channel applications, the RS422 interface links to higher-order systems in a typical way, observing
transmit (Tx), receive (Rx), and send timing (ST) connections. However, when used in two-channel applications, certain
criteria must be followed since there is one clock input for the two RS422 channels. The system functions correctly when
the following connections are observed and your data module has a terminal timing feature. Terminal timing is a common
feature in most synchronous data units that allows the module to accept timing from an external source. Using the
terminal timing feature, two-channel applications can be achieved if these connections are followed: the send timing

outputs from the multiplexer (data module 1) connects to the clock inputs of the UR RS422 interface in the usual way. In
addition, the send timing outputs of data module 1 are also paralleled to the terminal timing inputs of data module 2. By
using this configuration, the timing for both data modules and both UR RS422 channels is derived from a single clock
source. As a result, data sampling for both of the UR RS422 channels is synchronized via the send timing leads on data
module 1, shown as follows. If the terminal timing feature is not available or this type of connection is not wanted, the
G.703 interface is a viable option that does not impose timing restrictions.
Figure 3-51: Timing configuration for RS422 two-channel, three-terminal application

Data module 1 provides timing to the G60 RS422 interface via the ST(A) and ST(B) outputs. Data module 1 also provides
timing to data module 2 TT(A) and TT(B) inputs via the ST(A) and AT(B) outputs. The data module pin numbers have been
omitted in the figure because they vary by manufacturer.
3.4.5.3 Transmit timing
The RS422 interface accepts one clock input for transmit timing. It is important that the rising edge of the 64 kHz transmit
timing clock of the multiplexer interface is sampling the data in the center of the transmit data window. Therefore, it is
important to confirm clock and data transitions to ensure proper system operation. For example, the following figure
shows the positive edge of the Tx clock in the center of the Tx data bit.

3.4.5.4 Receive timing
The RS422 interface utilizes NRZI-MARK modulation code and therefore does not rely on an Rx clock to recapture data.
NRZI-MARK is an edge-type, invertible, self-clocking code.
To recover the Rx clock from the data-stream, an integrated digital phase lock loop (DPLL) circuit is utilized. The DPLL is
driven by an internal clock, which is 16-times over-sampled, and uses this clock along with the data-stream to generate a
data clock that can be used as the serial communication controller (SCC) receive clock.

and 74 modules are used in two-terminal with a redundant channel or three-terminal configurations where channel 1 is
employed via the RS422 interface (possibly with a multiplexer) and channel 2 via direct fiber.
AWG 20 to 24 twisted shielded pair wiring is recommended for external RS422 connections. Ground the shield only at one
end. For the direct fiber channel, address power budget issues properly.
When using a laser interface, attenuators can be necessary to ensure that you do not exceed
maximum optical input power to the receiver.

3.4.8 IEEE C37.94 interface
IEEE C37.94 is a standard interface between teleprotection equipment and digital multiplexers.
The UR-series IEEE C37.94 modules (module types 2G, 2H, 2I, 2J, 76, and 77) are designed to interface with IEEE C37.94
compliant digital multiplexers or an IEEE C37.94 compliant interface converter for use with direct input and output
applications. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer
and a teleprotection device. Data speed is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n
= 1, 2,…, 12. The UR-series C37.94 communication modules are either 64 kbps (with n fixed at 1) or 128 kbps (with n fixed at
2). The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from the standpoint of
framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048
kbps.
The specifications for the module are as follows:
•
IEEE standard — C37.94 for 1  128 kbps optical fiber interface (for 2G and 2H modules) or C37.94 for 2  64 kbps
optical fiber interface (for 76 and 77 modules)
•
Fiber-optic cable type — 50 nm or 62.5 μm core diameter optical fiber
•
Fiber-optic mode — multimode
•
Fiber-optic cable length — up to 2 km
•
Fiber-optic connector — type ST
•
Wavelength — 820 ±40 nm
•
Connection — as per all fiber-optic connections, a Tx-to-Rx connection is required
The UR-series C37.94 module can be connected directly to any compliant digital multiplexer that supports the IEEE C37.94
standard. The figure shows the concept.

The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a noncompliant digital multiplexer via an optical-to-electrical interface converter that supports the IEEE C37.94 standard. The
following figure shows the concept.
Figure 3-56: IEEE C37.94 connection to non-compliant digital multiplexer
In 2008, GE Grid Solutions released revised modules 76 and 77 for C37.94 communication to enable multi-ended fault
location functionality with firmware 5.60 release and higher. All modules 76 and 77 shipped since the change support this
feature and are fully backward compatible with firmware releases below 5.60. For customers using firmware release 5.60
and higher, the module can be identified with "Rev D" printed on it and is to be used on all ends of G60 communication for
two and three terminal applications. Failure to use it at all ends results in intermittent communication alarms. For
customers using firmware revisions below 5.60, it is not required to match the revision of the modules installed.
The UR-series C37.94 communication module has six switches to set the clock configuration. The following figure shows
the functions of these control switches.
Figure 3-57: Switches
For the internal timing mode, the system clock is generated internally. Therefore, set the timing switch selection to internal
timing for relay 1 and loop timed for relay 2. There must be only one timing source configured.
For the looped timing mode, the system clock is derived from the received line signal. Therefore, set the timing selection to
loop timing mode for connections to higher order systems.
The IEEE C37.94 communications module cover removal procedure is as follows:
1.
With power to the relay off, remove the IEEE C37.94 module (type 2G, 2H, 2I, 2J, 76, or 77 module) as follows. Record
the original location of the module to help ensure that the same or replacement module is inserted into the correct
slot.
2.
Simultaneously pull the ejector/inserter clips located at the top and bottom of each module in order to release the
module for removal.

3.4.9 C37.94SM interface
The UR-series C37.94SM communication modules (2A and 2B) are designed to interface with modified IEEE C37.94
compliant digital multiplexers or IEEE C37.94 compliant interface converters that have been converted from 820 nm multimode fiber optics to 1300 nm ELED single-mode fiber optics. The IEEE C37.94 standard defines a point-to-point optical link
for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard
provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94SM communication module is 64 kbps only
with n fixed at 1. The frame is a valid ITU-recommended G.704 pattern from the standpoint of framing and data rate. The
frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.
The specifications for the module are as follows:
•
Emulated IEEE standard — Emulates C37.94 for 1  64 kbps optical fiber interface (modules set to n = 1 or 64 kbps)
•
Fiber-optic cable type — 9/125 m core diameter optical fiber
•
Fiber-optic mode — Single-mode, ELED compatible with HP HFBR-1315T transmitter and HP HFBR-2316T receiver
•
Fiber-optic cable length — Up to 11.4 km

3.5 Field and stator ground modules
GPM field and stator ground fault protection modules can be used with the G60. The stator ground unit, for example, works
in combination with the G60 to provide 100% stator ground fault protection during generator start-up, running, and
stopped conditions. The GPM units are set up and run from the G60. See the GPM Field and Stator Ground Fault Protection
Modules Quick Reference Guide for information on their installation.
The field ground protection modules are used with the G60 in the following configurations:
•
Field low voltage protection system (order code GPM-F-L) for voltages up to 600 V DC
•
Field high voltage protection system (order code GPM-F-H) for voltages greater than 600 V DC
•
Stator protection system (order code GPM-S)
These systems are illustrated for comparative purposes in the figure.
With GPM-S, use a CT/VT module with Sensitive Ground capability (for example 8G, 8J, 8M, 8R) to connect stator ground
protection CT (204-SD-43737) input to the G60 device.

3.8.1 Set IP address in UR
3
Implement IP addresses for the computer and a G60 device as follows.
The UR family supports the use of subnetworks as documented in RFC 950, which divides class-based networks into
subnetworks (non-CIDR). The classes and IP address ranges are defined as follows.
Table 3-7: IP address classes
Classes
IP address range
Default subnet mask address
UR devices
A
1.0.0.0 to 127.255.255.255
255.0.0.0
65,535 or more
B
128.0.0.0 to 191.255.255.255
255.255.0.0
255 to 65,534
C
192.0.0.0 to 223.255.255.255
255.255.255.0
0 to 254
D
224.0.0.0 to 239.255.255.255
(Reserved for multicasting)
E
240.0.0.0 to 255.255.255.255
(Reserved)
Both network and subnet addresses are contained within a range. The number of hosts determines the class and
addresses as follows:
•
Class A 255.0.0.0 — The first octet (255) specifies the network, the second to fourth octets (0) specify the subnet and
host. Use this class when you have more than 65,535 hosts (UR devices).
•
Class B 255.255.0.0 — The first two octets (255) specify the network, the third octet (0) specifies the subnet, and the
fourth octet (0) specifies the host. Use this class when you have 255 to 65,534 hosts (UR devices).
•
Class C 255.255.255.0 — The first three octets (255) specify the network and the last octet (0) specifies the subnet and
host. Use this class when you have up to 254 hosts (UR devices).
An example of implementation is one computer and one UR device. Because there is one UR device, class C addressing is
required. So we use UR 192.167.2.x with subnet mask 255.255.255.0 and computer 192.167.3.x with subnet mask
255.255.255.0.
For older, non-CIDR routing protocols, such as RIP version 1, follow these restrictions:
•
Identical subnet masks — Use a single mask for all subnets within a network
•
Contiguous subnets — The subnets must be contiguous and not split among networks. The subnets cannot pass
traffic through other networks.
The IP and subnet addresses need to be added to the UR for Ethernet communication.
For serial communication, for example using the front RS232 port and the Quick Connect feature, the addresses are not
required, but typically they are entered to add/configure devices for regular use.

3.8.5 Automatic discovery of UR devices
The EnerVista UR Setup software can find and communicate to all UR-family devices located on an Ethernet network.
Using the Discover button in the Device Setup window, a single click of the mouse triggers the software to detect any URs
located on the network. This is done by searching a range of IP addresses based on the subnet mask of the computer.
When a UR device is detected, the EnerVista UR Setup software proceeds to configure all settings and order code options
in the window. This feature allows the user to identify and interrogate all UR devices at a location.
Examples of address ranges are as follows:
•
If the host has an IP address of 3.94.247.10 and its subnet mask is 255.255.252.0, then the host’s subnet is 3.94.244.0,
and the possible IP addresses in this subnet are
3.94.244.1 to 254
3.94.245.1 to 254
3.94.246.1 to 254
3.94.247.1 to 254
The discover function scans all those possible IP addresses to detect UR relays.
•
If the host has an IP address of 3.94.247.145 and its subnet mask is 255.255.255.128, then the host’s subnet is
3.94.247.128, and the discover function scans IP addresses of 3.94.247.128 to 3.94.248.254 for UR relays
To automatically add UR devices:
1.
In the EnerVista software, click the Device Setup button. The window opens.
2.
Click the Discover button. The software searches for UR devices on the computer subnet and adds any found to the
Online Window area. If a required device is not found, add it manually as outlined earlier.

3.10 Set up CyberSentry and change default password
If and when first using CyberSentry security, use the following procedure for set up.
1.
Log in to the relay as Administrator by using the VALUE keys on the front panel or through EnerVista connected serially
(so that no IP address is required). If logging in through EnerVista choose Device authentication (see figure). Enter the
default password "ChangeMe1#". Note that the "Lock relay" setting needs to be disabled in the Security > Supervisory
menu. When this setting is disabled, configuration and firmware upgrade are possible. By default, this setting is
disabled.
2.
Enable the Supervisor role if you have a need for it.
3.
Make any required changes in configuration, such as setting a valid IP address for communication over Ethernet.
4.
Log out of the Administrator account by choosing None.
Next, device or server authentication can be chosen on the login screen, but the choice is available only in EnerVista. Use
Device authentication to log in using the five pre-configured roles (Administrator, Supervisor, Engineer, Operator, Observer,
or Administrator and Supervisor when Device authentication is disabled). When using a serial connection, only Device
authentication is supported. When Server authentication is required, characteristics for communication with a RADIUS
server must be configured on the UR. This is possible only through the EnerVista software. The RADIUS server itself also
must be configured. At the end of this instruction manual, the appendix called RADIUS Server Configuration gives an
example of how to set up a simple RADIUS server. Once both the RADIUS server and the parameters for connecting the UR
to the server have been configured, you can choose Server authentication on the login screen of EnerVista.

During the commissioning phase, you have the option to bypass the use of passwords. Do so by enabling the Bypass
Access setting under Settings > Product Setup > Security > Supervisory. Be sure to disable this bypass setting after
commissioning the device.
You can change the password for any role either from the front panel or through EnerVista. If using EnerVista, navigate to
Settings > Product Setup > Security. Change the Local Administrator Password, for example. It is strongly recommended
that the password for the Administrator be changed from the default. Changing the passwords for the other three roles is
optional.
3.11 Import settings
The following file types can be imported:
•
URS — UR settings file (firmware version7.3x or earlier)
•
IID — Instantiated IED capability description file — Actual settings on UR
•
CID — Configured IED description file — Settings sent to the UR (may or may not be actual settings). When using IEC
61850, network settings can also be configured by accepting a CID file that includes them, as long as the IP address of
at least one port is manually configured in the relay before the CID file is sent and the IP address matches that in the
file.
The import is done in the Offline Window area.
To import a settings file:
1.
In the Offline Window area, right-click the device and select the Add Device from File option. The device is that from
which you want to import settings.
2.
If required, change the Files of type drop-down list.
3.
Select the file to import.
To apply the settings to a live device:
1.
Drag-and-drop the device entry from the Offline Window area to its entry in the Online Window area.
Individual settings also can be dragged and dropped between Online and Offline Window areas.
The order codes must match.
This is what happens:
•
CID — For version 7.30 or later, a new URS file generates and moves into a new device folder, generating SCL files from
the new URS file. Files in the folder have new time stamps. The CID file retains its time stamp.
•
URS — When not IEC 61850 and version is lower than 7.30, the file is added and time stamp is unchanged. When
clicking in the software on the tree element, a device folder is created, the original file moves into it, and time stamp is
on the URS file is retained.

and the "Last modified" time stamp on the URS file changes.
3.12 Connect to D400 gateway
3
A GE Multilin D400 Substation Gateway can be used to collect data from UR devices in a local area network (LAN). It collects
metering, status, event, and fault report data from serial or LAN-based intelligent substation devices, and it pre-processes
the data. The D400 supports up to 16 serial and eight network connections, with multiple devices possible on each serial
connection. Up to 10 concurrent file transfer sessions are possible, meaning data for up to 10 URs can be transferred at
the same time and any additional IEDs are queued on a first-come-first-served basis. The D400 can then upload files to a
demilitarized zone (DMZ) server at the enterprise level.
Setup is as follows. For UR devices with the CyberSentry software option, when there is a need to retrieve periodically the
logs from the UR securely without a human interface, the following approach can be used. See the D400 manual for
configuration details to achieve it.
A UR in the substation can authenticate a user either connecting to a RADIUS server or on the device itself. This depends on
the user name used for authentication on a connection. The D400 connects to the UR device using an Ethernet, USB, or
serial port on the UR. At the other end, the cable attaches to the rear of D400. Use the D400 software to configure a serial
or network communication/connection for the UR, then to configure the IED device blocks/clients for the UR, and then to
configure record retrieval. Once configured, the UR and D400 use a keyfile authentication mechanism to establish
communication.
For UR devices with the IEC 61850 software option, also use the D400 IEC 61850 Loader software.
When a D400 detects new files available for download from a UR, it connects to the UR and reads the files via sFTP
protocol. The following files can be transferred:
•
Oscillography files
•
Event records
•
Log files
•
Configuration (setting) files
The D400 information is viewable in its software and in a web browser.
3.12.1 Oscillography files
These are stored in COMTRADE format in the D400 folder system using the UR site and device name.
3.12.2 Event records
These are stored as the EVT.TXT file in the D400 folder system using the UR site and device name.
3.12.3 Log files
Log files can be retrieved for UR 7.0 and later. The following file types are possible, stored in the D400 folder system using
the UR site and device name:
•
factory_event.txt — Information about change methods and origins. Saved with a "_YYMMDDhhmmss" retrieval time
stamp, for example FACTORY_EVENT_170525183124.TXT.
•
setting_changes.log — Information on what settings have been changed. Saved with a "_YYMMDDhhmmss" retrieval

This chapter explains the EnerVista software interface, the front panel interface, logic diagrams, and Engineer interface for
logic design and monitoring.
4.1 EnerVista software interface
4.1.1 Introduction
The EnerVista UR Setup software provides a single facility to configure, monitor, maintain, and troubleshoot relays
connected over local or wide-area networks. It can be used while disconnected (offline) or connected (online) to a UR
device. In offline mode, settings files can be created for eventual downloading to the device. In online mode,
communication with the device is real-time.
The EnerVista UR Setup software is provided with every G60. This chapter outlines the EnerVista software interface. The
EnerVista UR Setup help file in the software also provides details for getting started and using the software interface.
4.1.2 Settings files
The EnerVista software supports the following three ways of handling changes to relay settings:
•
In offline mode (relay disconnected) to create or edit relay settings files for later transfer to relays
•
While connected to a relay to modify relay settings, and then save the settings to the relay
•
Create/edit settings files and then write them to the relay while connected to the relay
See the back up section in the Maintenance chapter for instructions on how to create a settings file either offline or online.
Settings files are organized on the basis of file names assigned by the user. A settings file contains data pertaining to the
following types of relay settings:
•
Device definition
•
Product setup
•
System setup
•
FlexLogic
•
Grouped elements
•
Control elements
•
Inputs/outputs

When a settings file is loaded to a G60 that is in-service, the following sequence occurs:
1.
The G60 takes itself out of service.
2.
The G60 issues a UNIT NOT PROGRAMMED major self-test error.
3.
The G60 closes the critical fail contact.
The Maintenance chapter outlines how to use a settings file in the .urs format for backup and restore.
4.1.3 Event viewing
In online or offline mode, you can view and analyze data generated by triggered parameters as follows:
•
Event recorder — The event recorder captures contextual data associated with the last 1024 events, listed
chronologically from most recent to oldest
•
Oscillography — The oscillography waveform traces and digital states are used to provide a visual display of power
system and relay operation data captured during specific triggered events
Event records are viewable at software and device-specific levels. Access the former under Admin > Event Log > View.
Access the latter under Actual Values > Records > Event Record.
Event record entries for CyberSentry are explained in the next chapter. The following table outlines some software-level
entries.

4.1.7 Settings templates
Settings file templates simplify the configuration and commissioning of multiple relays that protect similar assets. An
example is a substation that has 10 similar feeders protected by 10 UR F60 relays.
In these situations, typically 90% or greater of the settings are identical among devices. The templates allow engineers to
configure and test these common settings, then lock them so that they are not available to users. For example, locked
settings can be hidden from view for field engineers, allowing them to quickly identify and concentrate on specific settings.
The remaining settings (typically 10% or less) can be specified as editable and made available to field engineers installing
the devices. These are settings such as protection element pickup values and CT and VT ratios.
The settings template mode allows the user to define which settings are visible in the software. Settings templates can be
applied to both settings files (settings file templates) and online devices (online settings templates). The functionality is
identical for both purposes.
Template mode is available in the English software only.
Settings file conversion from previous firmware versions is supported.
4.1.7.1 Enable the settings template
The settings file template feature is disabled by default. It can be enabled in offline or online mode.

4.1.9 Settings file traceability
A traceability feature for settings files allows the user to quickly determine if the settings in a G60 device have been
changed since the time of installation from a settings file. When a settings file is transferred to a G60 device, the date, time,
and serial number of the G60 are sent back to EnerVista UR Setup and added to the settings file on the local computer. This
information can be compared with the G60 actual values at any later date to determine if security has been compromised.
The traceability information is only included in the settings file if a complete settings file is either transferred to the G60
device or obtained from the G60 device. Any partial settings transfers by way of drag and drop do not add the traceability
information to the settings file.
4-12
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 4: INTERFACES
ENERVISTA SOFTWARE INTERFACE
Figure 4-13: Settings file traceability
4
With respect to the figure, the traceability feature is used as follows.
•
The transfer date of a settings file written to a G60 is logged in the relay and can be viewed in the EnerVista software
or the front panel display. Likewise, the transfer date of a settings file saved to a local computer is logged in the
EnerVista software.
•
Comparing the dates stored in the relay and on the settings file at any time in the future indicates if any changes have
been made to the relay configuration since the settings file was saved.
4.1.9.1 Settings file traceability information
The serial number and file transfer date are saved in the settings files when they are sent to a G60 device.
The G60 serial number and file transfer date are included in the settings file device definition within the EnerVista UR Setup
offline window as shown in the example.

ACTUAL VALUES  PRODUCT INFO  MODEL INFORMATION  SERIAL NUMBER
ACTUAL VALUES  PRODUCT INFO  MODEL INFORMATION  LAST SETTING CHANGE
4.1.9.3 Additional traceability rules
The following additional rules apply for the traceability feature:
•
If the user changes any settings within the settings file in the offline window, then the traceability information is
removed from the settings file
•
If the user creates a new settings file, then no traceability information is included in the settings file
•
If the user converts an existing settings file to another revision, then any existing traceability information is removed
from the settings file
•
If the user duplicates an existing settings file, then any traceability information is transferred to the duplicate settings
file

As an example, if you set up a single-line diagram with two breakers and six switches, then eight of the side pushbuttons
are used automatically for control of the breakers and switches. Side pushbuttons 9 and 10 are available. In the single-line
diagram, let us set side pushbutton 9 to clear event records as follows:
•
Show side pushbutton 9 on the graphical front panel — Click the PB symbol in the toolbar, then set Side button 9 to
pushbutton 9 in the drop-down list. This pushbutton then displays when appropriate on the right side of the screen
display.
•
Program event record clearing — Set Settings > Product Setup > Clear Relay Records > Clear Event Records to
FlexLogic operand PUSHBUTTON 9 ON
•
Program pushbutton 9 — Set Settings > Product Setup > User-Programmable Pushbuttons > Pushbutton 9
Function to "Self-reset." When pressed, pushbutton 9 clears the event records.
To instead set the second user pushbutton (not a side pushbutton) to clear events, follow the second and third bullet
points, selecting settings of PUSHBUTTON 2 ON and Pushbutton 2.
Metering components
Metering components show dynamically the value of a FlexAnalog operand or actual value. Up to 16 metering
components can be added to each single-line diagram.
To add a metering component, click the M symbol in the toolbox, then click in the window. Drag it to its final location.
Double-click it to open the properties window. The figure shows the properties that can be edited.

Status components
Status components show dynamically the value of a FlexLogic operand. Up to 16 can be used in a diagram and 30 in all
single-line diagrams.
An example is to show the Off or On state of the ANY MAJOR ERROR FlexLogic operand. The name of the operand displays in
the single-line diagram editor, then as Off or On on the graphical front panel.
To add a status component, click the S symbol in the toolbox, then click in the window. Drag it to its final location. Doubleclick it to open the properties window. Properties that can be edited include parameter (any FlexLogic operand), text color
background color, and on and off text.
Optionally add a text label to display beside the status.

Text components show a single line of user-configured text.
Up to 16 text components can be used per single-line diagram.
To add a text component, click the T symbol in the toolbox, then click in the window. Drag it to its final location. Doubleclick it to open the properties window. Properties that can be edited are text, color, and size.
Annunciator
An annunciator is a grid of small windows for alarms, actual values, self-test messages, and product information.
The graphical front panel emulates a conventional annunciator panel. The annunciator has 96 windows, each with a
description of the alarm condition that lights the window. The windows are arranged in rows and columns of 3 x 4, 4 x 6, or
6 x 8 over several pages. Each window can have up to three lines of configurable text, and one line can instead be a
metered value. Normally the window background is dark, and when the configured FlexLogic operand becomes On, the
window lights up.
The figure shows that two alarms are active. One alarm is configured red and the other alarm is configured blue. The red
alarm type is Self Reset, so the alarm displays in a solid color. The blue alarm type is Acknowledgeable, so the alarm flashes
until it is acknowledged, for example by navigating with the arrow keys and pressing the ENTER button. The alarm then
remains blue until the trigger condition is eliminated.

To display the annunciator, press the Home pushbutton, then the Annunciator Tab pushbutton. If there is one or more
window in alarm or requiring reset, the annunciator page showing the first of these opens. Otherwise the first annunciator
page opens.
Alarms do not display automatically. Set the Home page and/or rolling pages to display annunciator pages.
The Tab pushbutton labels populate with the annunciator pages. The label text for each annunciator page is configurable
and displays in the header and Tab label. The current page has a blue Tab label. Tab labels for annunciator pages that
have an active window (that is, on, latched, or unacknowledged) are red. Pages where alarms are not triggered have a grey
Tab label. Pages that have no configured windows do not have Tab pushbuttons and do not display.
The Up, Down, Left, and Right pushbuttons cause the selection to move one window in the indicated direction. Pressing the
Right pushbutton past the last window in a row scrolls the display to any next annunciator page, not the next row. The
behavior is similar for the other pushbuttons, for example pressing the Up pushbutton while in the top row goes to any
previous page. If no previous page exists, no action occurs.
Annunciator windows are positioned statically, so that all windows are visible no matter their state.
Alarm types of each window can be configured as Self Reset, Latched, or Acknowledgeable. In Self Reset mode, the
window lighting follows the state of the configured FlexLogic operand. The self-reset mode alarm sequence conforms to
ISA-18.1-1979 (R2004) standard type A 4 5 6.

the relay is in (online) Programmed mode (under Settings > Product Setup > Installation)
•
TROUBLE — Indicates that the relay has detected an internal problem. Check the self-test messages outlined at the
end of the Commands and Targets chapter, and view the event records under Actual Values > Records. For a beta /
pre-release, this LED is always on.
•
TEST MODE — Indicates that the relay is in test mode. For information, see the Test Mode section in the Settings
chapter.
•
TRIP — Indicates that the selected FlexLogic operand serving as a trip input has operated. Set the operand under

command to reset the latch.
•
ALARM — Indicates that the FlexLogic operand serving as an alarm switch has operated. Set the operand under
Settings > Product Setup > User-Programmable LEDs > Trip & Alarm LEDs. This indicator never latches.
•
PICKUP — Indicates that an element is picked up. This indicator never latches.
The event-cause indicators in the first column are as follows.
Event-cause LEDs are below the status LEDs. They are turned on or off by protection elements that have their respective
target setting selected as either “Enabled” or “Latched.” If a protection element target setting is “Enabled,” then the
corresponding event-cause LEDs remain on as long as the operand associated with the element remains asserted. If a

protection element target setting is “Latched,” then the corresponding event-cause LEDs turn on when the operate
operand associated with the element is asserted and remains on until the RESET button on the front panel is pressed after
the operand is reset.
All elements that are able to discriminate faulted phases can independently turn off or on the phase A, B, or C LEDs. This
includes phase instantaneous overcurrent, phase undervoltage, and so on. This means that the phase A, B, and C operate
operands for individual protection elements are ORed to turn on or off the phase A, B, or C LEDs.

User-programmable event-cause indicators
Event-cause LEDs are below the status LEDs. They are turned on or off by protection elements that have their respective
target setting selected as “Self-Reset” or “Latched.” If set to “Self-Reset,” then the corresponding event cause LED remains
on as long as the operand associated with the element remains asserted. If set to “Latched” and asserted, then it remains
on until the operand is reset and then a reset command initiated.
All elements that are able to discriminate faulted phases can independently turn on or off the phase A, B, or C LEDs. This
includes phase instantaneous overcurrent, phase undervoltage, and so on. This means that the phase A, B, and C operate
operands for individual protection elements are ORed to turn on or off the phase A, B, or C LEDs.
The LEDs have defaults and can be configured to show instead the status of any FlexLogic operand.
The labelling area has a clear cover for custom labels. A utility is available to print stick-on labels, as outlined later in this
chapter.
These LEDs are programmed by default as follows:
•
PICKUP — LED 6 — Indicates that an element is picked up, and hence a trip can be imminent
•
VOLTAGE — LED 7 — Indicates voltage was involved
•
CURRENT — LED 8 — Indicates current was involved

The G60 can interface with associated circuit breakers. In many cases the application monitors the state of the breaker,
that can be presented on front panel LEDs, along with a breaker trouble indication. Breaker operations can be manually
initiated from the front panel keypad or automatically initiated from a FlexLogic operand. A setting is provided to assign
names to each breaker; this user-assigned name is for the display of related flash messages. These features are provided
for two breakers; the user can use only those portions of the design relevant to a single breaker, which must be breaker 1.
It is assumed in the following discussion that the SETTINGS  SYSTEM SETUP  BREAKERS  BREAKER 1(2)  BREAKER

again within that time, a signal is created that can be programmed to operate an output relay to
close breaker 1.
(2)
USER 3 OFF/ON
To Open BKR1-(Name)
If the USER 3 key is pressed, this message appears for 20 seconds. If the USER 3 key is pressed
again within that time, a signal is created that can be programmed to operate an output relay to
open breaker 1.
(3)
BKR2-(Name) SELECTED
USER 2=CLS/USER 3=OP
If the USER 1 key is pressed at this step, this message appears showing that a different breaker is
selected. Three possible actions can be performed from this state as per (1), (2) and (3). Repeatedly
pressing the USER 1 key alternates between available breakers. Pressing keys other than USER 1, 2,
or 3 at any time cancels the breaker control function.
4.2.9.4 Control of one breaker
For this application, the relay is connected and programmed for breaker 1 only. Operation for this application is identical to
that described in the previous section for two breakers.
4.2.10 Change passwords
The information in this section refers to password security. For information on how to set the password for the first time or

CHAPTER 4: INTERFACES
The G60 supports password entry from a local or remote connection.
Local access is defined as access to settings or commands via the front panel. This includes both keypad entry and the
RS232 port. Remote access is defined as access to settings or commands via any rear communications port. This includes
both Ethernet and RS485 connections. Any change to the local or remote password enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the G60, the remote password must be used. If the
connection is to the RS232 port of the front panel, the local password must be used.
There are two user security access levels, setting and command, for which you can set a password for each. Use of a
password for each level controls whether users can enter commands or change settings. Another option is to specify
setting and/or command access for individual user accounts.

By default, when an incorrect Command or Setting password has been entered via the front panel three times within five
minutes, the LOCAL ACCESS DENIED FlexLogic operand is set to “On” and the G60 does not allow settings or command level
access via the front panel for five minutes.
By default, when an incorrect Command or Setting password has been entered via any external communications interface
three times within five minutes, the REMOTE ACCESS DENIED FlexLogic operand is set to “On” and the G60 does not allow
settings or command access via the any external communications interface for five minutes. The REMOTE ACCESS DENIED
FlexLogic operand is set to “Off” after five minutes for a Command password or 30 minutes for a Settings password.
These default settings can be changed in EnerVista under Settings > Product Setup > Security.
4.3 Logic diagrams
Logic diagrams in this instruction manual provide an overview of function and settings. A logic diagram is based on
•
Inputs-on the left side, which are setting and operands
•
Logical gates, which is Boolean algebra to combine logical lines using AND, OR, NOT, and other gates to get a new
logical state
•
Logical operators, which are timers, one-shot operations, latches, and so on
•
Outputs-on the right side, which are products of the manipulations with inputs, logical gates, and logical operators to
produce new operands and define the output state of the element
True and false values are denoted by 1 and 0 respectively. A function usually is high/on/enabled when 1.
Reading from right to left in the following diagram, the TRIP BUS 1 OP and TRIP BUS 1 PKP FlexLogic operands on the right side
are triggered when either the settings or reset latch in the middle of the diagram is triggered. When this applies, the TRIP
BUS 1 OP operand is triggered after the delay set by the TRIP BUS 1 PICKUP DELAY or TRIP BUS 1 RESET DELAY setting, while the
TRIP BUS 1 PKP operand initiates immediately. The settings or reset latch in the middle of the diagram is triggered as follows.
•
For the reset, one of three conditions are required to meet the OR requirement shown at the bottom left. That is, the
TRIP BUS 1 LATCHING setting must be 0=Disabled (which is negated by the NOT function to become 1=Enabled), output
from the TRIP BUS 1 RESET FlexLogic operand must be 1, or output from the RESET OP FlexLogic operand must be 1.
•
For the settings, one of 16 input conditions at the top left must be met for the OR, the TRIP BUS 1 FUNCTION must be
Enabled, and the TRIP BUS 1 BLOCK output must output as 0, which is then negated/reversed by NOT to become 1.

Bottom logic — Create events at 100 ms intervals for the same 10 second period
4.4.1.2 Add existing FlexLogic equations
A logic diagram can be created using existing FlexLogic equations (this section) or by creating new ones (next section).
When using existing equations, you modify them in the FlexLogic Equation Editor in the Offline Window area, then apply
them.
The FlexLogic Equation Editor window is in view-only mode when the Logic Designer is open. To instead work in the
FlexLogic Equation Editor, close the Logic Designer window, then re-open the FlexLogic Equation Editor.
To create a logic diagram using existing FlexLogic equations:
1.
In the Offline Window area, modify the FlexLogic for the device under FlexLogic > FlexLogic Equation Editor. If the
device is not listed, right-click the device in the Online Window area and select the Add Device to Offline Window
option.
Upon saving the modified FlexLogic, a yellow icon appears for the device in the Offline Window area to indicate that
the logic differs from the Online device.
2.
In the Offline Window area, access Engineer for the device, then Logic Designer. The logic opens.
3.
Click the Edit > Auto Populate Workbook menu item. If the software prompts if you want to keep or discard existing
sheets, either is acceptable, with the older excluded sheeted being denoted by brackets, such as < Sheet 1 >. The logic
displays in the various tabs. The FlexLogic created in the equation editor appears in Sheet 1, for example.
4.4.1.3 Create logic diagram
Upon access of the Logic Designer, the FlexLogic equations of the device display. You can create new logic in new sheets
or modify the ones that display.
This procedure uses input / output logic as an example.
To create a logic diagram:
1.
In the Offline Window area, access Engineer for the device, then Logic Designer. If the device is not listed, right-click
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL

Add the output blocks to the logic diagram. For example, click the I/O Tokens tab, click the Virtual Output element,
then click in the logic sheet to add it. Double-click the block on the sheet to configure it. For the name, make it unique.
The figure shows virtual output 61 is being added, with a suffix of "io" added to the name to make it unique. Note that
the outline color of a block is red until it is configured, and that this properties window varies by block and the
selectable options by order code.
Figure 4-72: Configuring an output block
8.
Connect the input blocks to the output blocks by drawing a line as follows. Click the Drawing Tools tab, then select the
Line option. The cursor needs to be at the connection point to end the line, not elsewhere on the block. Note that the
outline color is no longer red on the blocks.

10. Check for any blocks that have a red outline. These are invalid. Fix them before continuing, for example by configuring
them.
11. Compile the logic diagram to check for errors by clicking the Compile button at the bottom left or by pressing the F7
key.
If prompted about a message about sorting, click Yes to apply the default (for this example), which can be automatic
sorting based on an algorithm that applies fastest execution time.
With successful compiling, the file is saved and the FlexLogic equations populate automatically. Scroll up through the
compile messages, with the red errors being the only messages that require fixing before proceeding.
The figure shows that we forgot to add the "Io" suffix to the names of virtual outputs 62 and 63, as indicated by
"Warning: Virtual output xx using default name." This warning is a minor warning.
The warning "input using disabled feature" means that input needs to be enabled. Double-click the block, click the
View Associated Screen button, enable the setting, save, and recompile.
The output and messages are explained in the next section.

4.4.1.4 Compiled results and warning messages
When a yellow caution icon displays in the Offline Window area, it means that the settings file is not synchronized with the
online device. Right-click the device in the Offline Window area, and select the Update SCL files option. SCL refers to the
Substation Configuration Language. An Instantiated IED capability description (IID) file is an example of an SCL file and
contains the actual settings on a UR device.
Figure 4-78: Settings files not synchronized between offline and online files
When the Update SCL files option is selected, the CID and IID files in the device folder are updated by the user
configuration in the IEC 61850 panel and thereby become synchronized. The CID file and the IID file (depending on the
preference 'Do not update IID file when updating SCL files') are updated. If the CID file is not already there, it is generated.

4.4.1.6 Connect two logic diagrams
When the logic is complex and requires two sheets, for example, these two sheets can be connected. By connecting them,
the logic is continuous from one sheet to the next.
To connect two logic diagrams:
1.
In the first sheet, click the I/O Tokens tab.
2.
Scroll to the bottom, and click and drag the Tag Out element to the sheet where the next sheet is to connect.
3.
Double-click the element and in the window that opens, give it a name, such as "To Sheet 2" or "To IO Sheet 2."

4.
In the second sheet, click and drag the Tag In element to the sheet where the first sheet is to connect.
5.
Double-click the element and in the window that opens, select the first sheet from the drop-down list to connect the
two sheets.
6.
Save the work.
4.4.1.7 Optimize the logic
The number of available FlexLogic entries depends on firmware, for example 515 or 1024 lines. The software can
automatically optimize a logic diagram to reduce space and free up entries.
To optimize the logic:
1.
In Engineer, under File > Preferences, select the Compiler option. Ensure that the Optimize Compiled Output option is
enabled.
2.
Run the compiler again, for example by clicking the Compile button at the bottom left of the software. The results
display in the Optimization Summary. Changes also display when the FlexLogic Equation Editor is accessed. The logic
diagram does not change. In the example shown, no lines were saved to free up space.
Figure 4-81: Code optimization results

G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 4: INTERFACES
FLEXLOGIC DESIGN USING ENGINEER
4.4.1.8 Change logic order
The order in which the FlexLogic is populated in the FlexLogic Equation Editor window depends on settings.
First, when automatic sorting is not enabled, the sequence in which the blocks were drawn is followed.
Second, the order in which equations are executed can be manually changed, as outlined here.
Third, automatic sorting can be set in preferences, as outlined here. It is enabled by default and means that an algorithm is
implemented to give best results and quickest performance, For example, the block with the fastest execution time is
entered first in the FlexLogic. When two block functions have the same execution time the block drawn first displays first in
the FlexLogic. For example, drawing input 61 to output 61, then input 62 to output 62 causes the input/output 61 to be
entered into the FlexLogic first. Automatic sorting takes precedence over manual sort; if you enable this option, manual
sorting is not implemented.
To manually change logic order:
1.
In the compile area, click the VO Order tab.
2.
If the window is blank, click the Refresh button.
3.
Select an entry and click the up or down arrow. To cancel any manual changes, click the Sort or Refresh button.
4.
Recompile. The change is not executed or saved if automatic sorting is enabled.
Figure 4-82: Ordering FlexLogic entries
4
To set automatic sorting:
1.
In Engineer, under File > Preferences, select the Compiler option. The Automatically Sort VOs option means that the
block with the fastest execution time is entered first in the FlexLogic. When two block functions have the same
execution time the block drawn first displays first in the FlexLogic. For example, drawing input 61 to output 61, then
input 62 to output 62 causes the input/output 61 to be entered into the FlexLogic first.
4.4.1.9 Search logic
Items that can be searched in a logic diagram include gates, Input, Contact Input, Contact Output, Timer, Virtual Output,
Tag In, Tag Out, and User-programmable LED. A search can be performed while designing or monitoring.
To search:
1.
In the compiler area of Engineer, click the Search tab.
2.
Use one of the following methods to set search criteria:
–
Select an element from the first drop-down list. Results display automatically.
–
Type in the second text string box, or select any of the 32 previous searches from the drop-down list. Click the
Search button. Any results display.
The search applies to all tabs, not just the active tab.
3.
Double-click a search result to view the item.

You can also select an element from the drop-down list on the toolbar. It is then highlighted in the logic diagram.
4.4.1.10 Exclude sheet from compile
4
While designing the FlexLogic equations, entire sheets can be removed from the compile logic. This allows the user to test
various schemes by placing schemes on separate sheets and including either sheet at compile time.
To exclude a sheet:
1.
In the Logic Designer window, right-click the tab and select the Exclude from Compile option so that the check mark
displays. When sheets are excluded, a message displays with each compile that "excluded sheets will not be reflected
in the RPN." An excluded sheet is denoted with end brackets, similar to < Sheet 1 >.

Figure 4-85: Tab excluded from compiling
4.4.2 Send file to and from device
With the logic diagram created, compiled, and errors eliminated, the FlexLogic can be sent to a live device. And,
conversely, a file from a live device can be added to the Offline Window area for additional work.
To send a file to a device:
1.
In the Offline Window area of the software, right-click the device name and select the Write Settings to Device option.
A prompt can appear that the URS file has been repaired; acknowledge the message.
2.
When a window opens, select the device to which you want to send the file, then click the Send button and confirm.
The order codes must match. The file is sent to the live device. Any errors can be viewed in the log file at the prompt.

To import a file from a device:
1.
Close all open files in Engineer that relate to the device, else a message displays to that effect, for example to close
the FlexLogic view associated with the file. When the file is not associated with a live device, a message displays to
that effect; you need to identify the device to which you want to send the file. The order codes must match.
2.
Right-click the device in the Online Window area and select the Add Device to Offline Window option. After you enter
a name for the file, it is written to the Offline Window area.
4.4.3 Monitor logic
After creating the logic diagram, validating it, and uploading the FlexLogic to a device, the results from the device can be
viewed.
The following checks are performed automatically when switching from design to monitoring, and prompts display when
necessary:
•
Verify that the order code of the linked relay matches the settings file
•
Verify that the version of the linked relay matches the settings file
•
Verify that the FlexLogic Equation Editor of the linked relay matches the settings file. Solution: Compile the FlexLogic
logic diagram and send the settings file to the relay.
•
Verify that the FlexLogic Timers of the linked relay match the settings file. Solution: Compile the FlexLogic logic
diagram and send the settings file to the relay.
•
If the settings file contains a serial number lock, then verify that the serial number of the linked relay matches the
settings file
To view results:
1.
In the Offline Window area of the software, expand the Engineer entry for the device.
2.
Double-click the Logic Designer entry and Compile the logic.
3.
Double-click the Logic Monitor entry, or click the M button in the toolbar at the top of the window. With successful
launch, the logic displays and a green indicator displays at the bottom of the tab.
When the file is not associated with a live device, a message displays to that effect; you need to identify the device to
which you want to send the file. The order codes must match between the Offline Window and the Online Window.
When the device is offline, a message indicates problems communicating with the device.
When the devices are not synchronized, a message indicates the FlexLogic does not match the settings file. To send
the offline file to the device, right-click the device name and select the Write Settings to Device option.
When the state of a symbol is OFF, the symbol is shown in the default color or no color.
When a symbol's state changes to ON, the symbol and connection line turns green.
The state of some symbols can either be unknown or the state transitions faster than the update interval. For these
two cases, the state of the symbol is considered 'UNKNOWN' and the symbol is outlined in red.
The colors for the ON and Unknown state can be customized in the Preferences.
The figure shows that the software is communicating with devices (square green indicator) and that a minor error is
present (green box outline). In this case, the battery is weak and needs to be replaced. This can be viewed as the
Replace Battery message on the front panel of the device and in the EnerVista software under Actual Values > Front

Repeat Symbol — Enable this feature to add element blocks rapidly in sequence, for example when you have inputs 1 to
10, without having to select the element each time. Select the element block from the toolbox, click the diagram, then
continue to click to add additional blocks.
Use first available VO / Timer — When enabled and you copy and paste a virtual output or timer element, the numbering
continues in sequence. For example, you copy timer 5 and paste it as timer 6. When disabled and you copy and paste a
virtual output or timer element, the same number is used. For example, you copy timer 5 and paste it as timer 5.
Auto-Save Logic Designer every x minutes — Logic diagrams with changes are saved automatically according to this
interval. The range is 5 minutes (default) to 30 minutes. With auto-save, the file extension of the saved file is .auto. This file
remains until you save the file manually.
Auto Populate
These options work in the Edit > Auto Populate Workbook function.
VOs per Worksheet — When an existing settings file is opened in the Logic Designer, the Logic Designer populates the
canvas and attempts to evenly distribute the Virtual Output circuits across multiple sheets. A value of 100 in this setting
places all FlexLogic equations on a single sheet until there are 100, then the next ones are placed on another sheet. A value
of 1 places each Virtual Output circuit on a separate sheet.
Show / FlexLogic Merge / Show Unused — If Show Contact Outputs and Show LEDs are selected, for example, the function
places Contact Output and User-programmable LED symbols for settings that are configured. If you disable the LED check
boxes, then the LED tab/sheet does not display when you next open the Logic Designer window. The settings apply to all
products, not just the active window when it is next opened. Close then reopen the Logic Designer window for the setting
to take effect.
Compiler
Show Warnings — Options to filter the messages that display when logic compiles.
Minor — Enable to display minor errors. An example is using the default values of an element added to the diagram, such

the element to rename it.
Major — Enable to display major errors. Examples are an input that does not have a corresponding output, using disabled
features, and failing to connect a symbol. Fix these errors.
Setting — Enable to display error message related to settings, such as an improperly configured setting, such as using ON
or OFF.
Automatically Sort VOs — When enabled, the logic is compiled with an algorithm to give best results and quickest
performance, for example the fastest logic first. The fastest logic displays in the FlexLogic Equation Editor output as the
first entries in the table. Use sorting when virtual outputs have dependencies on other virtual outputs. This setting takes
precedence over order set manually in the VO Order tab in the compiler.
When disabled, the sequence in which the blocks were drawn is followed.
Optimize Compiled Output — With this option enabled, the software automatically optimizes a logic diagram to reduce
space and free up FlexLogic entries. Run the compiler again, for example by clicking the Compile button at the bottom left
of the software. The number of saved lines displays in the Optimization Summary. Changes also display when the
FlexLogic Equation Editor is accessed. The logic diagram does not change.

Timing
Timing Information can be displayed in the monitoring window. This timing information is only an approximate
representation of how Engineer sees transitions. Use the device's Event Record to view accurate timing information.
The timing information can also be streamed to a comma-separated values (CSV) spreadsheet.
The timing information displayed and recorded can be filtered based on six categories. If a category is not selected, any
timing information related to that category does not display and is not recorded to the CSV file.
Show Timing Information in Output Window — Enable to display times in the monitoring window.
Because of the update rate of the Logic Monitoring, the timing information cannot be used as an accurate representation
of the events that occur within the relay. Use instead the device's event record. Timing information can be delayed by 30
seconds.
Save Timing Information to CSV File — Enable to write timing information in a spreadsheet. The timing information is
recorded in a text file that uses commas to separate each of the fields. This file uses the extension CSV that is supported
by any spreadsheet application.
Every change written to the CSV file requires a timestamp.
The format for the timing information in the output window is as follows:

devicename offline
yyyy/mm/dd hh:dd:ss
devicename ONLINE
yyyy/mm/dd hh:dd:ss

5.2.1 Introduction to elements
For URs, the term element is used to describe a feature that is based around a comparator. The comparator is provided
with an input (or set of inputs) that is tested against a programmed setting (or group of settings) to determine if the input is
within the defined range that sets the output to logic 1, also referred to as setting the flag. A single comparator can make
multiple tests and provide multiple outputs. For example, the time overcurrent comparator sets a pickup flag when the
current input is above the setting and sets an operate flag when the input current has been at a level above the pickup
setting for the time specified by the time-current curve settings. All comparators use analog actual values as the input.
An exception to this rule is digital elements, which use logic states as inputs.
Elements are arranged into two classes, grouped and control. Each element classed as a grouped element is provided with
six alternate sets of settings, in setting groups numbered 1 through 6. The performance of a grouped element is defined by
the setting group that is active at a given time. The performance of a control element is independent of the selected active
setting group.
The main characteristics of an element are shown on a logic diagram. This includes the inputs, settings, fixed logic, and the
output operands generated. The previous chapter explains how to read a logic diagram, and the abbreviations used in a
diagram are defined in the Abbreviations chapter.
Some settings are specified in per-unit (pu) calculated quantities:
pu quantity = (actual quantity) / (base quantity)
Where the current source is from a single current transformer (CT), the base quantity is the nominal secondary or primary
current of the CT. Use the secondary current base to convert per-unit settings to/from a secondary current value, and use
the primary current base to convert to/from a primary current value.
Where the current source is the sum of two or more CTs with different nominal primary current, the primary base quantity
is the largest nominal primary current. For example, if CT1 = 300 / 5 A and CT2 = 100 / 1 A, then in order to sum these, CT2
is scaled to the CT1 ratio. In this case, the base quantity is 300 A primary, 5 A secondary for CT1, and 300/(100/1) = 3 A
secondary for CT2.
5-4
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
OVERVIEW
For voltage elements, the primary base quantity is the nominal phase-to-phase primary voltage of the protected system
provided that the VT ratio setting is set to the nominal ratio of the VTs and the secondary voltage setting is set to the
phase-to-phase voltage seen by the relay when the voltage of the protected system in nominal. The UR uses the
convention that nominal voltages in a three-phase system are phase-to-phase voltages.
For example, on a system with a 13.8 kV nominal primary voltage, the base quantity is 13800 V. With 14400:120 V deltaconnected VTs, the secondary base quantity and secondary voltage setting is:
Eq. 5-1
For wye-connected VTs, the primary and secondary base quantities are as before, but the secondary voltage setting (here
a phase-to-ground value) is:
Eq. 5-2
Many settings are common to most elements, outlined as follows:
•
FUNCTION setting — This setting programs the element to operate when selected as “Enabled.” The factory default is
“Disabled.” Once “Enabled,” any element associated with the function becomes active and all options become
available.
•
NAME setting — This setting is used to uniquely identify the element.
•
SOURCE setting — This setting is used to select the AC source to be monitored. See the Introduction to AC Sources
section later.
•
PICKUP setting — For simple elements, this setting is used to program the level of the measured parameter above or
below which the pickup state is established. In more complex elements, a set of settings can be provided to define the
range of the measured parameters that cause the element to pick up.
•
PICKUP DELAY setting — This setting sets a time-delay-on-pickup, or on-delay, for the duration between the pickup
and operate output states.
•
RESET DELAY setting — This setting is used to set a time-delay-on-dropout, or off-delay, for the duration between the
operate output state and the return to logic 0 after the input transits outside the defined pickup range.
•
BLOCK setting — The default output operand state of all comparators is a logic 0 or “flag not set.” The comparator
remains in this default state until a logic 1 is asserted at the RUN input, allowing the test to be performed. If the RUN
input changes to logic 0 at any time, the comparator returns to the default state. The RUN input is used to supervise
the comparator. The BLOCK input is used as one of the inputs to RUN control.
•
TARGET setting — This setting is used to define the operation of an element target message. When set to "Disabled,"
no target message or illumination of a front panel LED indicator is issued upon operation of the element. When set to
“Self-Reset,” the target message and LED indication follow the operate state of the element and self-resets once the
operate element condition clears. When set to “Latched,” the target message and LED indication remains visible after
the element output returns to logic 0 until a RESET command is received by the relay.
•
EVENTS setting — This setting is used to control whether the pickup, dropout, or operate states are recorded by the
event recorder. When set to “Disabled,” element pickup, dropout, or operate are not recorded as events. When set to
“Enabled,” events are created for
<Element> PKP (pickup)
<Element> DPO (dropout)
<Element> OP (operate)
The DPO event is created when the measure and decide comparator output transits from the pickup state (logic 1) to
the dropout state (logic 0). This can happen when the element is in the operate state if the reset delay time is not zero.
Not every operand of a given element in a UR relay generates events, only the major output operands. Elements,
asserting output per phase, log operating phase output only, without asserting the common three-phase operand
event.

OVERVIEW
CHAPTER 5: SETTINGS
5.2.2 Introduction to AC sources
5.2.2.1 Background
A mechanism called a source configures the routing of CT and VT input channels to measurement sub-systems. Sources, in
the context of UR series relays, refer to the logical grouping of current and voltage signals such that one source contains all
the signals required to measure the load or fault in a particular power apparatus. A given source can contain all or some of
the following signals: three-phase currents, single-phase ground current, three-phase voltages, and an auxiliary voltage
from a single VT for checking for synchronism.
The basic idea of an AC source is to select a point on the power system where the voltages and currents are of interest. To
illustrate the concept of sources, as applied to current inputs only, consider the breaker-and-a-half scheme that follows.
(The breaker-and-a-half scheme is used for illustrative purposes and is available on select UR products.) In this application,
the current flows as shown by the arrows. Some current flows through the upper bus bar to some other location or power
equipment, and some current flows into transformer winding 1. The current into winding 1 is the phasor sum (or difference)
of the currents in CT1 and CT2 (whether the sum or difference is used depends on the relative polarity of the CT
connections). The same considerations apply to transformer winding 2. The protection elements require access to the net
current for transformer protection, but some elements can need access to the individual currents from CT1 and CT2.
Figure 5-1: Breaker-and-a-half scheme
5
In conventional analog or electronic relays, the sum of the currents is obtained from an appropriate external connection of
all CTs through which any portion of the current for the element being protected can flow. Auxiliary CTs are required to
perform ratio matching if the ratios of the primary CTs to be summed are not identical. In the UR series of relays, provisions
have been included for all the current signals to be brought to the UR device where grouping, ratio correction, and
summation are applied internally via configuration settings.
A major advantage of using internal summation is that the individual currents are available to the protection device, for
example as additional information to calculate a restraint current, or to allow the provision of additional protection
features that operate on the individual currents, such as breaker failure.
Given the flexibility of this approach, it becomes necessary to add configuration settings to the platform to allow the user
to select which sets of CT inputs are to be added to form the net current into the protected device.
The internal grouping of current and voltage signals forms an AC source. This source can be given a specific name through
the settings and becomes available to protection and metering elements in the UR platform. Individual names can be
given to each source to help identify them for later use. For example, in the scheme shown in the preceding figure, the user
configures one source to be the sum of CT1 and CT2 and can name this source as “Wdg1 I.”

G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
Once the sources have been configured, the user has them available as selections for the choice of input signal for the
protection elements and as metered quantities.
5.2.2.2 CT/VT module configuration
CT and voltage transformer (VT) input channels are contained in CT/VT modules. The type of input channel can be phase/
neutral/other voltage, phase/ground current, or sensitive ground current. The CT/VT modules calculate total waveform
RMS levels, fundamental frequency phasors, symmetrical components, and harmonics for voltage or current, as allowed
by the hardware in each channel. These modules can calculate other parameters as directed by the CPU module.
A CT/VT module contains up to eight input channels, numbered 1 through 8. The channel numbering corresponds to the
module terminal numbering 1 through 8 and is arranged as follows. Channels 1, 2, 3, and 4 are always provided as a group,
hereafter called a “bank,” and all four are either current or voltage, as are channels 5, 6, 7, and 8. Channels 1, 2, 3 and 5, 6,
7 are arranged as phase A, B, and C respectively. Channels 4 and 8 are either another current or voltage.
Banks are ordered sequentially from the block of lower-numbered channels to the block of higher-numbered channels,
and from the CT/VT module with the lowest slot position letter to the module with the highest slot position letter, as follows.
Increasing slot position letter -->
CT/VT module 1
CT/VT module 2
CT/VT module 3
< bank 1 >
< bank 3 >
< bank 5 >
< bank 2 >
< bank 4 >
< bank 6 >
The UR platform allows for a maximum of six sets of three-phase voltages and six sets of three-phase currents. The result
of these restrictions leads to the maximum number of CT/VT modules in a chassis to three. The maximum number of
sources is six. A summary of CT/VT module configurations is as follows.
Item
Maximum number
CT/VT Module

CT Bank (3 phase channels, 1 ground channel)
4
5
VT Bank (3 phase channels, 1 auxiliary channel)
5.2.2.3 CT/VT input channel configuration
Upon relay startup, configuration settings for every bank of current or voltage input channels in the relay are generated
automatically from the order code. Within each bank, a channel identification label is assigned automatically to each bank
of channels in a given product. The bank naming convention is based on the physical location of the channels, required by
the user to know how to connect the relay to external circuits. Bank identification consists of the letter designation of the
slot in which the CT/VT module is mounted as the first character, followed by numbers indicating the channel, either 1 or 5.
See the HardFiber instruction manual for designations of HardFiber voltage and current banks.
For three-phase channel sets, the number of the lowest numbered channel identifies the set. For example, F1 represents
the three-phase channel set of F1/F2/F3, where F is the slot letter and 1 is the first channel of the three channels.
Upon startup, the CPU configures the settings required to characterize the current and voltage inputs, and it displays them
in the appropriate section in the sequence of the banks (as described earlier) as follows for a maximum configuration: F1,
F5, M1, M5, U1, and U5.

PASSWORD ACCESS
EVENTS: Disabled
Range: Disabled, Enabled
The G60 supports password entry from a local or remote connection.
Local access is defined as access to settings or commands via the front panel. This includes both keypad entry and the
RS232 port. Remote access is defined as access to settings or commands via any rear communications port. This includes
both Ethernet and RS485 connections. Any change to the local or remote password enables this functionality.
For a relay without a CyberSentry software option, any user can activate the RESET button or Reset/Acknowledge
an alarm in the Graphical Front Panel Annunciator without password entry.
ACCESS LEVEL — The "Restricted" option means that settings and commands can be accessed, but there is no access to
factory configuration. Access automatically reverts to the Restricted level according to the access level timeout setting
values. The access level is set to Restricted when control power is cycled.
5-8
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
The "Factory Service" level is not available and intended for factory use only.
There are two user security access levels, setting and command, for which you can set a password for each. Use of a
password for each level controls whether users can enter commands or change settings. Another option is to specify
setting and/or command access for individual user accounts.
•
•
Setting — Allows the user to make any changes to any of the setting values:
–
Changing any setting
–
Test mode operation
Command — Restricts the user from making any settings changes, but allows the user to perform the following
operations:
–
Changing the state of virtual inputs
–
Clearing the event records
–
Clearing the oscillography records
–
Changing the date and time
–
Clearing the breaker arcing current
–
Clearing energy records
–
Clearing the data logger
–
Clearing the user-programmable pushbutton states
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the G60, the remote password must be used. If the
connection is to the RS232 port of the front panel, the local password must be used.
The local setting and command sessions are initiated by the user through the front panel display and are disabled either
by the user or by timeout (via the setting and command level access timeout settings). The remote setting and command
sessions are initiated by the user through the EnerVista software and are disabled either by the user or by timeout.
The state of the session (local or remote, setting or command) determines the state of the following FlexLogic operands:
•
ACCESS LOC SETG OFF — Asserted when local setting access is disabled
•
ACCESS LOC SETG ON — Asserted when local setting access is enabled
•
ACCESS LOC CMND OFF — Asserted when local command access is disabled
•
ACCESS LOC CMND ON — Asserted when local command access is enabled
•
ACCESS REM SETG OFF — Asserted when remote setting access is disabled
•
ACCESS REM SETG ON — Asserted when remote setting access is enabled
•
ACCESS REM CMND OFF — Asserted when remote command access is disabled
•
ACCESS REM CMND ON — Asserted when remote command access is enabled
A command or setting write operation is required to update the state of the remote and local security operands
listed.
When a setting password or command password is set or updated, user access with a graphical front panel is
removed. Simply log in again on the graphical front panel.
When the setting password is set or updated, the graphical front panel Access Level displays as Command. This is
because the graphical front panel is a Modbus client and it does not have automatic access to the password
change.

As outlined in the previous section, there are two user security access levels, setting and command. Use of a password for
each level controls whether users can enter commands or change settings.
Proper password codes are required to enable each access level. When a CHANGE COMMAND PASSWORD or CHANGE
SETTING PASSWORD setting is programmed to “Yes” via the front panel interface, the following message sequence is
invoked:
1.
ENTER NEW PASSWORD: ____________.
2.
VERIFY NEW PASSWORD: ____________.
3.
NEW PASSWORD HAS BEEN STORED.
To gain write access to a “Restricted” setting, program the ACCESS LEVEL setting in the main security menu to “Setting” and
then change the setting, or attempt to change the setting and follow the prompt to enter the programmed password. If the
password is correctly entered, access is allowed. Access automatically reverts to the “Restricted” level according to the
access level timeout setting values and when power is cycled.
If the setting and command passwords are identical, then this one password allows access to both commands and
settings.
If a remote connection is established, local passcodes are not visible.

This menu displays when the ACCESS LEVEL setting is other than Restricted or Command.
The following access supervision settings are available.
INVALID ATTEMPTS BEFORE LOCKOUT — This setting specifies the number of times that an incorrect password can be entered
within a three-minute time span before lockout occurs. When lockout occurs, the LOCAL ACCESS DENIED or REMOTE ACCESS
DENIED FlexLogic operands are set to “On.” These operands are returned to the “Off” state upon expiration of the lockout.
PASSWORD LOCKOUT DURATION — This setting specifies the time that the G60 locks out password access after the number
of invalid password entries specified by the INVALID ATTEMPTS BEFORE LOCKOUT setting has occurred.
The G60 provides a means to raise an alarm upon failed password entry. If password verification fails while accessing a
password-protected level of the relay (either settings or commands), the UNAUTHORIZED ACCESS FlexLogic operand is
asserted. The operand can be programmed to raise an alarm via contact outputs or communications. This feature can be
used to protect against both unauthorized and accidental access attempts.
The UNAUTHORIZED ACCESS operand is reset with the COMMANDS  CLEAR RECORDS  RESET UNAUTHORIZED ALARMS
command. Therefore, to apply this feature with security, password-protect the Command level. The operand does not
generate events or targets.
If events or targets are required, the UNAUTHORIZED ACCESS operand can be assigned to a digital element programmed with
event logs or targets enabled.

This menu displays when the ACCESS LEVEL setting is other than Restricted or Command.
This feature provides a mechanism to prevent unauthorized or unintended upload of settings to a relay through the local
or remote interface.
The following settings are available through the local (front panel) interface only.
•
LOCAL SETTING AUTH — This setting is used for local (front panel or RS232 interface) setting access supervision. Valid
values for the FlexLogic operands are either “On” (default) or any physical “Contact Input ~~ On” value.
If this setting is “On,“ then local setting access functions as normal; that is, a local setting password is required. If this
setting is any contact input on FlexLogic operand, then the operand must be asserted (on) prior to providing the local
setting password to gain setting access.
If setting access is not authorized for local operation (front panel or RS232 interface) and the user attempts to obtain
setting access, then the UNAUTHORIZED ACCESS message displays on the front panel.
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.
•
REMOTE SETTING AUTH — This setting is used for remote (Ethernet or RS485 interface) setting access supervision.
If this setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is
required. If this setting is “Off,” then remote setting access is blocked even if the correct remote setting password is
provided. If this setting is any other FlexLogic operand, then the operand must be asserted (set as on) prior to
providing the remote setting password to gain setting access.
5
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.
•
ACCESS AUTH TIMEOUT — This setting represents the timeout delay for local setting access. This setting is applicable
when the LOCAL SETTING AUTH setting is programmed to any operand except “On.” The state of the FlexLogic operand
is monitored continuously for an off-to-on transition. When this occurs, local access is permitted and the timer
programmed with the ACCESS AUTH TIMEOUT setting value is started. When this timer expires, local setting access is
immediately denied. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the
timeout is restarted. The status of this timer updates every five seconds.
The following settings are available through the remote (EnerVista UR Setup) interface only. Select the Settings > Product
Setup > Security menu item to display the security settings window.

The Remote Settings Authorized setting is used for remote (Ethernet or RS485 interface) setting access supervision. If this
setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is required.
If this setting is “Off,” then remote setting access is blocked even if the correct remote setting password is provided. If this
setting is any other FlexLogic operand, then the operand must be asserted (on) prior to providing the remote setting
password to gain setting access.
The Access Authorized Timeout setting represents the timeout delay remote setting access. It applies when the Remote
Settings Authorized setting is programmed to any operand except “On” or “Off.” The state of the FlexLogic operand is
continuously monitored for an off-to-on transition. When this occurs, remote setting access is permitted, and the timer
programmed with the Access Authorized Timeout setting value is started. When this timer expires, remote setting access
is denied immediately. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the timeout
is restarted. The status of this timer updates every five seconds.
5.3.1.3 EnerVista security
Enable the security management system
Access to files is controlled by the operating system and EnerVista software as follows:
•
Access privileges to files are defined by the Windows operating system. A standard user does not have access to a file
created by an administrator or another user.
•
When the EnerVista UR Setup software security system is disabled (passwords are not required), all users have
administrator access
The EnerVista security system allows an administrator to manage access privileges of multiple users of EnerVista. It is
disabled by default to allow access to the device immediately after installation. When security is disabled, all users have
administrator access. GE recommends enabling the EnerVista security before placing the device in service.
To enable the security system and require password use:
1.
Select the Security > User Management menu to open the user management window.
2.
Enable the Enable Security check box in the lower-left corner to enable the security management system.
3.
Click the Ok button.
If you force password entry using this feature, ensure that you know the Administrator password. If you do not
know the password and are locked out of the software, reset the device to factory defaults as outlined later for
COMMANDS  RELAY MAINTENANCE  SERVICE COMMAND. When using CyberSentry, the default password is
"ChangeMe1#".

5.3.1.4 CyberSentry security
This feature requires a CyberSentry software option. See the Order Codes section in chapter 2 for details.
The EnerVista software provides the means to configure and authenticate the G60 access using either a server or the
device. Access to functions depends on user role.
The login screen of EnerVista has two options for access to the G60, these being Server and Device authentication.
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
5-15
PRODUCT SETUP
CHAPTER 5: SETTINGS
Figure 5-2: Login screen for CyberSentry
When the "Server" Authentication Type is selected, the G60 uses the RADIUS server and not its local authentication
database to authenticate the user.
When the "Device" button is selected, the G60 uses its local authentication database and not the RADIUS server to
authenticate the user. In this case, it uses built-in roles (Administrator, Engineer, Supervisor, Operator, Observer, or
Administrator and Supervisor when Device Authentication is disabled), as login accounts and the associated passwords
are stored on the G60 device. In this case, access is not user-attributable. In cases where user-attributable access is
required, especially for auditable processes for compliance reasons, use server authentication (RADIUS) only.
No password or security information is displayed in plain text by the EnerVista software or the UR device, nor are they ever
transmitted without cryptographic protection.
Only (TCP/UDP) ports and services that are needed for device configuration and for customer enabled features are
open. All the other ports are closed. For example, Modbus is on by default, so its TCP port 502, is open. But if
Modbus is disabled, port 502 is closed. This function has been tested and no unused ports have been found open.
5
When CyberSentry is enabled, Modbus communications over Ethernet is encrypted, which is not always tolerated by
SCADA systems. The UR has a bypass access feature for such situations, which allows unencrypted Modbus over Ethernet.
The Bypass Access setting is available on the SETTINGS  PRODUCT SETUP  SECURITY  SUPERVISORY screen. Note that
other protocols (DNP, 101, 103, 104, EGD) are not encrypted, and they are good communications options for SCADA
systems when CyberSentry is enabled.
When using the rear RS485 port and CyberSentry, registers can be read with a maximum buffer of 64 bytes. Settings may
not be written, so use another port or configure the SERIAL INACTIVITY TIMEOUT setting to a high value, such as eight
minutes, to give the relay enough time to finish the task.

LOGIN — This setting is applicable for Device authentication only. This setting allows a user to log in with a specific role, as
outlined here. For the Supervisor role, enable the “Supervisor Role” setting. Log out by right-clicking the device in EnerVista
and selecting the Disconnect option.
Whenever a new role is logged in, the user is prompted to enter a password. Passwords must obey the requirements
specified earlier in the chapter in the Password Requirements section.The UR device supports five roles. Roles have their
corresponding passwords, except the Observer role, which does not require a password. There are no time-outs for the
Administrator, Engineer, Operator, and Supervisor when logged in using the front panel; log out manually or use the
Command > Security commands in the software.
The roles are defined as follows:
5
•
Administrator — Complete read/write access to all settings and commands. This role does not allow concurrent
access. This role has an operand to indicate when it is logged on.
•
Engineer — Complete read/write access to all settings and commands except configuring Security settings and
firmware upgrades. This role does not allow concurrent access.
•
Operator — The Operator has read/write access to all settings under the Commands menu/section. This role does not
exist offline.
•
Supervisor — This is only an approving role. This role’s authentication commits setting changes submitted by
Administrator or Engineer. The Supervisor role authenticates to unlock the UR relay for setting changes and not
approve changes after the fact. Only a Supervisor can set the Settings Lock and Firmware Lock in the Security
settings. This role also has the ability to forcefully log off any other role and clear the security event log. This role can
also be disabled, but only through a Supervisor authentication. When this role is disabled its permissions are assigned
to the Administrator role.
•
Observer — This role has read-only access to all G60 settings. This role allows concurrent access but it has no
download access to any files on the device. Observer is the default role if no authentication has been done to the
device. This role displays as "None" on the front panel. When local authentication is used, no password is required for
this role. When RADIUS server authentication is used, a password is required.
The Factory service role is not available. It is for factory use only.
The Local Access Denied message on the front panel can mean that you need to log in to the UR in order to
complete the action.

CHAPTER 5: SETTINGS
DEVICE AUTHENTICATION — This setting is enabled by default, meaning "Yes" is selected. When enabled, Device
authentication with roles is enabled. When this setting is disabled, the UR only authenticates to the AAA server (RADIUS).
However, the Administrator and Supervisor (when enabled) remain active even after device authentication is disabled and
their only permission is to re-enable Device authentication. To re-enable Device authentication, the Supervisor unlocks the
device for settings changes, then the Administrator re-enables device authentication.
BYPASS ACCESS — The bypass security feature provides an easier access, with no authentication and encryption for those
special situations when this is considered safe. Only the Supervisor, or the Administrator when the Supervisor role is
disabled, can enable this feature.

The bypass options are as follows:
•

•
Remote — Bypasses authentication for RS485 and Ethernet
•
Local and Remote — Bypasses authentication for push buttons, keypad, RS232, RS485, and Ethernet
•
Pushbuttons — Bypasses authentication for front panel push buttons, including in the software. On the graphical front
panel, the authentication for side pushbuttons to control breakers and disconnects also is bypassed.
LOCK RELAY — This setting uses a Boolean value (Enabled/Disabled) to indicate if the device accepts settings changes and
5
whether the device can receive a firmware upgrade. This setting can be changed by the Supervisor role, if it is enabled, or
by the Administrator if the Supervisor role is disabled. The Supervisor role disables this setting for the relay to start
accepting settings changes, command changes, or firmware upgrade. After all the setting changes are applied or
commands executed, the Supervisor enables to lock settings changes.
Example: If this setting is enabled and an attempt is made to change settings or upgrade the firmware, the UR device
denies the settings changes or denies upgrading the firmware. If this setting is disabled, the UR device accepts settings
changes and firmware upgrade.
This role is disabled by default.
FACTORY SERVICE MODE — When Enabled, the device can go into factory service mode. For this setting to become enabled
a Supervisor authentication is necessary. The default value is Disabled.
SUPERVISOR ROLE — When Enabled, the Supervisor role is active. To Disable this setting a Supervisor authentication is
necessary. If disabled, the Supervisor role is not allowed to log in. In this case, the Administrator can change the settings
under the Supervisory menu.
If enabled, Supervisor authentication is required to change the settings in the Supervisory menu. If the Supervisor disables
their role after authentication, the Supervisor session remains valid until they switch to another role using MMI or until they
end the current Supervisor session if using communications.
This role is disabled by default.
SERIAL INACTIVITY TIMEOUT — The role logged via a serial port is auto logged off after the Serial Inactivity timer times out. A
separate timer is maintained for RS232 and RS485 connections. Set this value to a high number, such as eight minutes,
when using the rear RS485 terminals for settings write.
GE recommends setting this value to at least 3 minutes for the following scenario: while connected to a CyberSentry
device, with serial or USB cable connected to the front panel, and performing "Add Device to Offline Window" or an online/
offline comparison. With less than the recommended 3 minutes, the serial activity timeout interrupts the connection and
the security role login window appears. Upon login, the process resumes.

CyberSentry setup
When first using CyberSentry security, use the following procedure for setup.
1.
Log in to the relay as Administrator by using the VALUE keys on the front panel to enter the default password
"ChangeMe1#". Note that the Lock Relay setting needs to be disabled in the Security > Supervisory menu. When this
setting is disabled, configuration and firmware upgrade are possible. By default, this setting is disabled.
2.
Enable the Supervisor role if you have a need for it.
3.
Make any required changes in configuration, such as setting a valid IP address for communication over Ethernet.
4.
Log out of the Administrator account by choosing None.
5.
Next, Device or Server authentication can be chosen on the login screen, but the choice is available only in EnerVista.
Use Device authentication to log in using the five pre-configured roles (Administrator, Supervisor, Engineer, Operator,
Observer). When using a serial connection, only Device authentication is supported. When Server authentication is
required, characteristics for communication with a RADIUS server must be configured. This is possible only in the
EnerVista software. The RADIUS server itself also must be configured. The appendix called RADIUS Server at the end of
this instruction manual gives an example of how to set up a simple RADIUS server. Once both the RADIUS server and
the parameters for connecting the UR to the server have been configured, you can choose Server authentication on
the login screen of EnerVista.
The use of CyberSentry for devices communicating through an Ethernet-to-RS485 gateway is not
supported. Because these gateways do not support the secure protocols necessary to communicate
with such devices, the connection cannot be established. Use the device as a non-CyberSentry
device.
Users logged in through the front panel are not timed out and cannot be forcefully logged out by a
supervisor. Roles logged in through the front panel that do no allow multiple instances (Administrator,
Supervisor, Engineer, Operator) must switch to None (equivalent to a logout) when they are done in
order to log out.
For all user roles except Observer, only one instance can be logged in at a time, for both login by
front panel and software.
To configure Server authentication:
1.
In the EnerVista software, choose Device authentication and log in as Administrator.
2.
Configure the following RADIUS server parameters: IP address, authentication port, shared secret, and vendor ID.
3.
On the RADIUS server, configure the user accounts. Do not use the five pre-defined roles as user names (Administrator,
Supervisor, Engineer, Operator, Observer) in the RADIUS server. If you do, the UR relay automatically provides the
authentication from the device.
4.
In the EnerVista software, choose Server authentication and log in using the user name and password configured on
the RADIUS server for Server authentication login.

CHAPTER 5: SETTINGS
After making any required changes, log out.
When changing settings offline, ensure that only settings permitted by the role that performs the
settings download are changed because only those changes are applied.
Pushbuttons (both user-control buttons and user-programmable buttons) located on the front panel can be pressed by an
Administrator or Engineer role. This also applies to the RESET button, which resets targets, where targets are errors
displayed on the front panel or the Targets panel of the EnerVista software. The RESET button has special behavior in that it
allows these two roles to press it even when they are logged in through the RS232 port and not through the front panel.
To reset the security event log and self-test operands:
1.
Log in as Supervisor (if the role is enabled) or Administrator (if the Supervisor role is disabled) and execute a clear
security command under Commands > Security > Clear Security.

CHAPTER 5: SETTINGS
Some relay messaging characteristics can be modified to suit different situations using the display properties settings.
LANGUAGE — This setting selects the language used to display settings, actual values, and targets. This setting displays
when a language other than English was purchased, and the range depends on the order code of the relay.
For Japanese, the settings display in Japanese on the graphical front panel, while the keys printed on the panel are in
English.
For Japanese and Chinese, up to 10 characters can be input in a field on the graphical front panel, not 20.
With the graphical front panel, the language can be changed regardless of the language purchased. That is, all languages
can be used. If you select a language with which you are unfamiliar and want to switch back to English for example, the
menu order remains the same. That is, Settings is always second, Product Setup is always first, Display Properties is
always second, and Language is always first.
If the language is changed after entering user-configured names, such as relay names, the strings are not translated. For
example, a relay name is entered in English, the language is changed to Japanese, and the relay name remains in English.
Set the language before changing settings.
Restart the relay after changing the LANGUAGE setting.
The language can be selected also for the front panel in EnerVista under Maintenance > Change Front Panel.
The language of the EnerVista software can be changed under View > Language. Languages supported by the operating
system display; that is for Polish or Japanese to display, the software needs to be installed on a Polish or Japanese
operating system.

FLASH MESSAGE TIME — Flash messages are status, warning, error, and information messages displayed in response to
certain key presses during settings programming. These messages override any normal messages. Use this setting to
change the duration of flash messages on the display.
DEFAULT MESSAGE TIMEOUT — If the keypad is inactive for a period of time, the relay automatically reverts to a default
message. The inactivity time is modified using this setting to ensure that messages remain on the screen long enough
during programming or reading of actual values. This setting is not supported on the graphical front panel.
DEFAULT MESSAGE INTENSITY — To extend phosphor life in the vacuum fluorescent display, the brightness can be
attenuated during default message display. During keypad interrogation, the display always operates at full brightness.
This setting is not supported on the graphical front panel.
SCREEN SAVER FEATURE and SCREEN SAVER WAIT TIME — These settings are only visible if the G60 has a liquid crystal display
(LCD) and control its backlighting. When the SCREEN SAVER FEATURE is “Enabled,” the LCD backlighting turns off after the
DEFAULT MESSAGE TIMEOUT followed by the SCREEN SAVER WAIT TIME, provided that no keys have been pressed and no
target messages are active. When a keypress occurs or a target becomes active, the LCD backlighting turns on. These
settings are not supported on the graphical front panel.
CURRENT CUT-OFF LEVEL — This setting modifies the current cut-off threshold. Very low currents (1 to 2% of the rated value)
are very susceptible to noise. Some customers prefer very low currents to display as zero, while others prefer the current
to display even when the value reflects noise rather than the actual signal. The G60 applies a cut-off value to the
magnitudes and angles of the measured currents. If the magnitude is below the cut-off level, it is substituted with zero. This
applies to phase and ground current phasors as well as true RMS values and symmetrical components. The cut-off
operation applies to quantities used for metering, protection, and control, as well as those used by communications
protocols. Note that the cut-off level for the sensitive ground input is 10 times lower that the CURRENT CUT-OFF LEVEL
setting value. Raw current samples available via oscillography are not subject to cut-off.
VOLTAGE CUT-OFF LEVEL — This setting modifies the voltage cut-off threshold. Very low secondary voltage measurements
(at the fractional volt level) can be affected by noise. Some customers prefer these low voltages to be displayed as zero,
while others prefer the voltage to be displayed even when the value reflects noise rather than the actual signal. The G60
applies a cut-off value to the magnitudes and angles of the measured voltages. If the magnitude is below the cut-off level,
it is substituted with zero. This operation applies to phase and auxiliary voltages, and symmetrical components. The cut-off
operation applies to quantities used for metering, protection, and control, as well as those used by communications
protocols. Raw samples of the voltages available via oscillography are not subject to cut-off.
5-26
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
The CURRENT CUT-OFF LEVEL and the VOLTAGE CUT-OFF LEVEL are used to determine the metered power cut-off levels. The
power cut-off level is calculated using the following equations. For Delta connections:
Eq. 5-3
For Wye connections:
Eq. 5-4
Eq. 5-5
where VT primary = VT secondary  VT ratio and CT primary = CT secondary  CT ratio.
For example, given the following settings:
CURRENT CUT-OFF LEVEL: “0.02 pu”
VOLTAGE CUT-OFF LEVEL: “1.0 V”
PHASE CT PRIMARY: “100 A”
PHASE VT SECONDARY: “66.4 V”
PHASE VT RATIO: “208.00 : 1"
PHASE VT CONNECTION: “Delta”
We have:
CT primary = “100 A”, and
VT primary = PHASE VT SECONDARY x PHASE VT RATIO = 66.4 V x 208 = 13811.2 V
5
The power cut-off is therefore:
power cut-off= (CURRENT CUT-OFF LEVEL  VOLTAGE CUT-OFF LEVEL  CT primary  VT primary)/VT secondary
=(
 0.02 pu  1.0 V  100 A  13811.2 V) / 66.4 V
= 720.5 watts
Any calculated power value below this cut-off does not display. As well, the three-phase energy data do not accumulate if
the total power from all three phases does not exceed the power cut-off.
Lower the VOLTAGE CUT-OFF LEVEL and CURRENT CUT-OFF LEVEL with care as the relay accepts lower signals as valid
measurements. Unless dictated otherwise by a specific application, the default settings of “0.02 pu” for CURRENT
CUT-OFF LEVEL and “1.0 V” for VOLTAGE CUT-OFF LEVEL are recommended.
5.3.3 Graphical front panel

Range: yyyy-mm-dd, dd-mmm-yy, yyyy/mm/dd, m/d/yyyy, m/d/yy, mm/dd/yy, mm/dd/yyyy, yy/mm/dd
Default: yyyy-mm-dd
This setting specifies the format for dates on the graphical front panel. It applies to the page header, the events records,
the annunciator, and everywhere else a date displays on the panel. If the relay is synchronized to an external time
source via PTP, IRIG-B, SNTP, and so on, the date/time is shown in white, and otherwise in yellow.
yyyy — four-digit year, for example 2017
yy — two-digit year, for example 17 for 2017
mmm — abbreviation of month name, for example Jan for January
mm — two-digit month, for example 01 for January
m — one or two-digit month, for example 1 for January and 10 for October
dd — two-digit day, for example 08
d — one or two-digit day, for example 8 and 28
To set the date and time, access Synchronize Devices in the software, synchronize to a time source using Settings >
Product Setup > Real Time Clock, or synchronize to the computer using Commands > Set Date and Time.
Time Format
Range: hh:mm:ss, h:mm:ss tt
Default: hh:mm:ss
This setting specifies the format for time on the graphical front panel. It applies to the page header and everywhere else
a time displays on the panel. When the Date Format and the Time Format use the defaults, the date and time are
separated by the character "T" per the ISO convention, such as "2017-09-24T10:58:31". Otherwise the date and time are
separated by a space. If the relay is synchronized to an external time source via PTP, IRIG-B, SNTP, and so on, the date/
time is shown in white, and otherwise in yellow.
hh — two-digit hour, for example 02 for two o’clock
h — one or two-digit hour, for example 2 for two o’clock
mm — two-digit minute, for example 51 minutes
ss — two-digit second (can have a decimal and further digits appended), for example 16 seconds
tt — AM or PM based on 12 hour clock
If microseconds have to be displayed, for example, in the event records, the 24-hour clock is adopted. The representation
of an accumulated period (for example hh:mm) is not affected by the selected time format.
To set the date and time, access Synchronize Devices in the software or synchronize to a time source using Settings >
Product Setup > Real Time Clock.
5.3.3.2 Rolling mode
After a user-defined period of inactivity, the graphical front panel changes, or rolls, to user-selected pages. Up to 10 pages
can be specified. Similarly, the display backlight intensity is lowered to a specified level; lower intensity extends the life of
the display.
Each rolling page displays for a few seconds; duration cannot be set.

Default: 300 s
The screen saver mode extends the life of the display. After the amount of time set here, the screen saver activates and
the display intensity is reduced to the level set by the Screen Saver Intensity setting. When in rolling mode, rolling
continues while the screen saver is active. The screen saver terminates when rolling mode terminates. To disable the
screen saver, set the delay to 0.
Screen Saver Intensity
Range: 0, 10, 20, or 30 %
Default: 30 %
This setting sets the brightness of the display while the screen saver is active. For example, 0% means that the screen is
dark and nothing displays. Pressing a pushbutton or changing a setting in the software, for example, re-activates the
display.
Number of Rolling Mode Pages

G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
This feature allows FlexLogic operands to trigger page display on the graphical front panel. It consists of 64 setting pairs,
each with a condition and an activation page. The condition selects any FlexLogic operand. The activation page selects
any page available for the graphical front panel. The page opens whenever the selected operand transitions from Off to
On. The page remains open until rolling mode initiates, another trigger initiates from Configurable Navigation, or the Home
button is pressed.
Avoid selecting condition operands that are likely to operate simultaneously but activate different pages, as only one page
can be opened at a time. For example, do not select a single-line diagram page for breaker status open and select an
annunciator page for a trip alarm.
In the example shown, failure of any of the three Ethernet ports triggers the Product Information page to display. With
unauthorized access (such as wrong password), IRIG-B clock failure, or breaker trouble, the Event Records display. When a
breaker opens, a single-line diagram displays. For the Ethernet and IRIG-B failure operation to work, these functions also
have been enabled under Settings > Product Setup > User-Programmable Self Tests.

Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning userprogrammable pushbuttons to clear specific records is a typical application for these commands. Since the G60 responds
to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
Clearing records with user-programmable operands is not protected by the command password. However, userprogrammable pushbuttons are protected by the command password. Thus, if they are used to clear records, the userprogrammable pushbuttons can provide extra security if required.

RS485 COM2 RESPONSE
MIN TIME: 0 ms
Range: 0 to 1000 ms in steps of 10
The G60 is equipped with up to two independent serial communication ports. The faceplate RS232 port is intended for local
use and is fixed at 19200 baud and no parity. The rear COM2 port be used for either RS485 or RRTD communications.
It is important that the baud rate and parity settings agree with the settings used on the computer or other equipment that
is connected to these ports.
The RS485 port can be connected to a computer running the EnerVista UR Setup software. This software can be used to
download and upload setting files, view measured parameters, and upgrade the relay firmware. A maximum of 32 relays
can be daisy-chained and connected to a distributed control system (DCS), power line carrier (PLC), or computer using the
RS485 port.
The baud rate for standard RS485 communications can be selected as 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800,
33600, 38400, 57600, or 115200 bps. If COM2 is used for both a field ground module (GPM-F) and remote RTD unit (RRTD),
then the RS482 COM2 BAUD RATE is fixed at 19200 bps.
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
5-41
PRODUCT SETUP
CHAPTER 5: SETTINGS
For the RS485 port, the minimum time before the port transmits after receiving data from a host can be set. This
feature allows operation with hosts that hold the RS485 transmitter active for some time after each transmission.
If the COM2 USAGE setting is “RRTD only”, then the COM2 port is used to monitor the RTDs on a remote RTD unit. The remote
RTD unit uses the Modbus RTU protocol over RS485. The RRTD device must have a unique address from 1 to 254. The baud
rate for RRTD communications can be selected as 1200, 2400, 4800, 9600, or 19200 bps.
If the RS485 COM2 port is used for an RRTD, GPM-F, or RRTD and GPM-F, then there must not be any other devices
connected in the daisy-chain for any other purpose. The port is strictly dedicated to RRTD or GPM-F usage when COM2
USAGE is selected as “RRTD only,” “GPM-F only,” or “RRTD & GPM-F.”
The field ground module (GPM-F) has a fixed slave address of 1. Therefore, the RRTD SLAVE ADDRESS setting is applicable
only to the RRTD unit and has a setting rage of 2 to 254 if the COM2 USAGE is set as “RRTD & GPM-F.”
Restart the G60 for changes to the COM2 USAGE setting to take effect.
5.3.5.3 Ethernet network topology
The G60 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP
address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND
operation performed between their respective IP address and mask produces a different result. Communication becomes
unpredictable when more than one port is configured to the same subnet.

5.3.5.4 Network
As outlined in the previous section, when using more than one Ethernet port, configure each to belong to a different
network or subnet using the IP addresses and mask. Configure the network IP and subnet settings before configuring the
routing settings.
Follow the IP and subnet mask rules outlined in the Set IP Address in UR section of the Installation chapter.
To obtain a list of all port numbers used, for example for audit purposes, contact GE technical support with substantiating
information, such as the serial number and order code of your device.

The IP addresses are used with the DNP, Modbus/TCP, IEC 61580, IEC 60870-5-104, TFTP, HTTP, and PRP protocols. PRP is
explained in its own section later.
Use the front panel to change these settings. When online, the EnerVista software can be used to enable/disable each port
only. In the Offline Window area, all settings can be changed except port 2 redundancy (depending on firmware version).
When using GOOSE, in failover or PRP mode, port 3 configuration in the CID file is ignored. The Port 3 ConnectedAP
elements has no meaning, as ports 2 and 3 use the port 2 MAC address, IP address, and mask.
PRT1 (2 or 3) IP ADDRESS — This setting sets the port’s IPv4 address in standard IPV4 format. This setting is valid on port 3 if
port 2 REDUNDANCY is set to None.
PRT1 (2 or 3) SUBNET MASK — This setting sets the port’s IPv4 subnet mask in standard IPV4 format. This setting is valid on
port 3 if port 2 REDUNDANCY is set to None.
PRT1 (2 or 3) FUNCTION — This setting enable/disables network communication on the respective port. When the port
function is Disabled, the network traffic on this port is disabled. The PRT2 redundancy setting has no effect on this
functionality. The change takes effect upon relay restart.
PRT2 REDUNDANCY — Determines if ports 2 and 3 operate in redundant or independent mode. If the software options in the
order code include PRP, the available options are None, Failover, and PRP. If the software options in the order code do not
include PRP, the available options are None and Failover. In non-redundant mode (REDUNDANCY set to None), ports 2 and 3
operate independently with their own MAC, IP, and mask addresses. If REDUNDANCY is set to Failover, the operation of ports
2 and 3 is as follows:
•
Ports 2 and 3 use the port 2 MAC address, IP address, and mask
•
The configuration fields for IP address and mask on port 3 are hidden
•
Port 3 is in standby mode and does not actively communicate on the Ethernet network but monitors its link to the
Multilink switch. If port 2 detects a problem with the link, communications is switched to Port 3. Port 3 is, in effect,
acting as a redundant or backup link to the network for port 2. Once port 2 detects that the link between itself and the
switch is good and that communication is healthy for five minutes, then switching back to port 2 is performed. The
delay in switching back ensures that rebooted switching devices connected to the G60, which signal their ports as
active prior to being completely functional, have time to completely initialize themselves and become active. Once
port 2 is active again, port 3 returns to standby mode.
If REDUNDANCY is set to PRP, the operation of ports 2 and 3 is as follows:
•
Ports 2 and 3 use the port 2 MAC address, IP address, and mask
•
The configuration fields for IP address and mask on port 3 are overwritten with those from port 2. This is visible on the
front panel but not displayed in the EnerVista software.
•
Port 2 MCST ADDRESS field is visible
•
The port 2 PTP function still uses only port 2 and the port 3 PTP function still uses only port 3. The relay still
synchronizes to whichever port has the best master. When ports 2 and 3 see the same master, as is typically the case
for PRP networks, the port with the better connectivity is used.
Behavior for GOOSE messages is as follows:
•
If REDUNDANCY is set to Failover or PRP, In order to transmit a GOOSE message on port 2, the CID file must be
configured to have the corresponding GSE element in both ConnectedAPs S2 and S3. In the EnerVista software, the
TxGOOSE PORT ASSIGNMENT needs to be "Ports-1,2,3" to transmit GOOSE on both ports 1 and 2, or "Ports-2,3" to have
GOOSE only on port 2, with failover/ PRP.
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL

PRODUCT SETUP
CHAPTER 5: SETTINGS
•
If REDUNDANCY is set to PRP, the port 2 configured GOOSE message is simultaneously transmitted on ports 2 and 3
•
If REDUNDANCY is set to failover and the port 2 link fails, then only the port 2 configured GOOSE message is
transmitted on port 3
The two ports must be connected to completely independent LANs with no single point of failure, such as common
power supplies that feed switches on both LANs.
When REDUNDANCY is set to PRP or failover and the network path with resolved default gateway is broken, then the
ARP table needs approximately five seconds to rebuild. The layer 2 protocols (GOOSE and PTP) are not affected.
However, the TCP/IP or UDP protocols (MMS connections, DNP3.0, and so on) can require reconnection if their active
connection does not ride through re-transmission frames.
For any changes to this setting to take effect, restart the unit.
PRT2 PRP MCST ADDR — This setting allows the user to change the multicast address used by the PRP supervision frames.
This setting is available if REDUNDANCY is set to PRP. All devices in the same PRP network need to have the same multicast
address. Choose an address that does not conflict with another multicast protocol.
5.3.5.5 Far-End Fault Indication (FEFI)
Since 100BASE-FX does not support Auto-Negotiation, a Far-End Fault Indication (FEFI) feature is included since UR 7 that
allows for detection of link failures.
The purpose of the Far-End Fault feature is to allow the stations on both ends of a pair of fibers to be informed when there
is a problem with one of the fibers. Without the Far-End Fault feature, it is impossible for a fiber interface to detect a
problem that affects only its transmit fiber.
5
When the Far-End Fault feature is supported, a loss of receive signal (link) causes the transmitter to generate a Far-End
Fault pattern in order to inform the device at the far end of the fiber pair that a fault has occurred.
When the local receiver again detects a signal, the local transmitter automatically returns to normal operation.
If a Far-End Fault pattern is received by a fiber interface that supports the Far-End Fault feature and it is enabled, it reacts
by dropping the link as if there were no signal at all.
If the receiving interface does not support the Far-End Fault feature or has it disabled, an incoming Far-End Fault pattern is
ignored.
It is strongly recommended to have switches used for substation automation that support the Far-End Fault feature,
especially when UR 7 redundancy Failover is selected for redundancy.
5.3.5.6 Parallel Redundancy Protocol (PRP)
The G60 is provided with optional PRP capability. This feature is specified as a software option at the time of
ordering. See the Order Codes section in chapter 2 for details.
The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation
networks. It applies to networks based on Ethernet technology (ISO/IEC 8802-3) and is based on the second edition (July
2012) of IEC 62439-3, clause 4.
PRP is designed to provide seamless recovery in case of a single failure in the network, by using a combination of LAN
duplication and frame duplication. Identical frames are sent on two completely independent networks that connect source
and destination. Under normal circumstances both frames reach the destination and one of them is sent up the OSI stack
to the destination application, while the second one is discarded. If an error occurs in one of the networks and traffic is
prevented from flowing on that path, connectivity is provided through the other network to ensure continuous
communication. Take care when designing the two LANs, so that no single point of failure (such as a common power
supply) is encountered, as such scenarios can bring down both LANs simultaneously.
5-46
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
Figure 5-16: Example of parallel redundant network
PRP uses specialized nodes called doubly attached nodes (DANPs) for handling the duplicated frames. DANP devices have
an additional module, called a Link Redundancy Entity (LRE). LRE is responsible for duplicating frames and adding the
specific PRP trailer when sending the frames out on the LAN, as well as making decisions on received frames as to which
one is sent up the OSI stack to the application layer and which one is discarded. LRE is responsible for making PRP
transparent to the higher layers of the stack.
In addition, there is a second type of specialized device used in PRP networks, called RedBox, with the role of connecting
Single Attached Nodes (SANs) to a redundant network.
UR relays implement the DANP functionality. The RedBox functionality is not implemented.
The original standard IEC 62439-3 (2010) was amended to align PRP with the High-availability Seamless Redundancy (HSR)
protocol. To achieve this, the original PRP was modified at the cost of losing compatibility with the PRP 2010 version. The
revised standard IEC 62439-3 (2012) is commonly referred to as PRP-1, while the original standard is PRP-0. The UR relays
support PRP-1.
The relay implements PRP on two of its Ethernet ports, specifically Ports 2 and 3 of the CPU module. Use the previous
section (network port configuration) to configure PRP.
PRP is purchased as a separate option. If purchased (valid order code), PRP can be enabled in configuration through a
setting available on the network configuration menu, REDUNDANCY, which already has the capability of enabling failover
redundancy. The options on this setting must be changed to accommodate two types of redundancy: failover and PRP.
When REDUNDANCY is set to either failover or PRP, the ports dedicated for PRP (Ports 2 and 3) operate in redundant mode.
In this mode, Port 3 uses the MAC, IP address, and mask of Port 2.

Add and delete static routes
Host routes are not supported at present.
The routing table configuration is available on the serial port and front panel. This is a deliberate decision, to avoid loss of
connectivity when remotely configuring the G60.
By default, the value of the destination field is 127.0.0.1 for all static routes (1 to 6). This is equivalent to saying that the
static routes are not configured. When the destination address is 127.0.0.1, the mask and gateway also must be kept on
default values.
By default, the value of the route gateway address is 127.0.0.1. This means that the default route is not configured.
To add a route:
5
1.
Use any of the static network route entries numbered 1 to 6 to configure a static network route. Once a route
destination is configured for any of the entries 1 to 6, that entry becomes a static route and it must meet all the rules
listed in the next section, General Conditions to be Satisfied by Static Routes.
2.
To configure the default route, enter a default gateway address. Once a default gateway address is configured, it
must be validated against condition 2 of the General Conditions to be Satisfied by Static Routes, where the route
gateway must be on a connected network.
To delete a route:
1.
Replace the route destination with the default loopback address of 127.0.0.1. When deleting a route, the mask and
gateway also must be brought back to default values.
2.
Delete the default route by replacing the default gateway with the default value of 127.0.0.1.
General conditions to be satisfied by static routes
The following rules are validated internally:
•
The route mask has IP mask format. In binary this needs to be a set of contiguous bits of 1 from left to right, followed
by one or more contiguous bits of 0.
•
The route destination and mask must match. This can be verified by checking that
RtDestination and RtMask = RtDestination
Example of good configuration: RtDestination = 10.1.1.0; Rt Mask = 255.255.255.0
Example of bad configuration: RtDestination = 10.1.1.1; Rt Mask = 255.255.255.0
The following rules must be observed when you configure static routes:
•
The route destination must not be a connected network
•
The route gateway must be on a connected network. This rule applies to the gateway address of the default route as
well. This can be verified by checking that:
(RtGwy & Prt1Mask) == (Prt1IP & Prt1Mask) || (RtGwy & Prt2Mask) == (Prt2IP & Prt2Mask) || (RtGwy & Prt3Mask) == (Prt3IP
& Prt3Mask)
where
& is the bitwise-AND operator
== is the equality operator
|| is the logical OR operator

PRODUCT SETUP
Routing behavior compared to previous releases
Prior to release 7.10, UR devices did not have an explicit manner of configuring routes. The only available route was the
default route configured as part of the network settings (port gateway IP address). This limited the ability to route to
specific destinations, particularly if these destinations were reachable through a different interface than the one on which
the default gateway was.
Starting with UR 7.10, up to six static network routes can be configured in addition to a default route. The default route
configuration was also moved from the network settings into the routing section.
The figure shows an example of topology that benefits from the addition of static routes.
Figure 5-17: Using static routes
5
In the figure, the UR connects through the following two Ethernet ports:
•
Port 1 (IP address 10.1.1.2) connects the UR to LAN 10.1.1.0/24 and to the Internet through Router1. Router1 has an
interface on 10.1.1.0/24 and the IP address of this interface is 10.1.1.1.
•
Port 2 (IP address 10.1.2.2) connects the UR to LAN 10.1.2.0/24 and to the EnerVista software through Router2. Router2
has an interface on 10.1.2.0/24 and the IP address of this interface is 10.1.2.1.
The configuration before release 7.10 was as follows:
•
PRT1 IP ADDRESS = 10.1.1.2
PRT1 SUBNET IP MASK = 255.255.255.0
PRT1 GWY IP ADDRESS = 10.1.1.1
PRT2 IP ADDRESS = 10.1.2.2
PRT2 SUBNET IP MASK = 255.255.255.0
The behavior before release 7.10 was as follows. When sending packets to EnerVista, the UR noticed that the destination
was not on a connected network and it tried to find a route to destination. Since the default route was the only route it
knew, it used it. Yet EnerVista was on a private network, which was not reachable through Router1. Hence a destination
unreachable message was received from the router.
The configuration starting with release 7.10 is as follows:
•
PRT1 IP ADDRESS = 10.1.1.2
PRT1 SUBNET IP MASK = 255.255.255.0
PRT2 IP ADDRESS = 10.1.2.2
PRT2 SUBNET IP MASK = 255.255.255.0
IPV4 DEFAULT ROUTE: GATEWAY ADDRESS = 10.1.1.1
STATIC NETWORK ROUTE 1: RT1 DESTINATION = 10.1.3.0/24; RT1 NET MASK = 255.255.255.0; and RT1 GATEWAY =
10.1.2.1
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL

PRODUCT SETUP
CHAPTER 5: SETTINGS
The behavior since release 7.10 is as follows. There is one added static network route to the destination 10.1.3.0/24, where
a computer running EnerVista is located. This static route uses a different gateway (10.1.2.1) than the default route. This
gateway is the address of Router2, which has knowledge about 10.1.3.0 and is able to route packets coming from the UR
and destined to EnerVista.

The serial communication ports utilize the Modbus protocol, unless the port is configured for DNP or IEC 60870-5-103
operation. This allows the EnerVista UR Setup software to be used on the port. UR devices operate as Modbus slave
devices only.
For more information on the protocol, including the memory map table, see the UR Family Communications Guide.
MODBUS SLAVE ADDRESS — When using the Modbus protocol on the RS232 port, the G60 responds regardless of the
MODBUS SLAVE ADDRESS programmed. For the RS485 port, each device on the serial bus must have a unique slave address
from 1 to 254. Address 0 and addresses from 248 and up are reserved by the Modbus protocol specification, and so their
use here is not recommended. Address 0 is the broadcast address to which all Modbus slave devices listen. Addresses do
not have to be sequential, but no two devices can have the same address or conflicts resulting in errors occur. Generally,
starting at 1, set each device added to the link to use the next higher address. When using Modbus TCP/IP, the client must
use the programmed MODBUS SLAVE ADDRESS value in the Unit Identifier field.
MODBUS TCP PORT NUMBER — Modbus over TCP/IP can also be used on any of the Ethernet ports. The listening TCP port 502
is reserved for Modbus communications, and only in exceptional cases when MODBUS TCP PORT NUMBER is set to any other
port. The MODBUS TCP PORT NUMBER setting sets the TCP port used by Modbus on Ethernet. A MODBUS TCP PORT NUMBER of
0 disables Modbus over TCP/IP, meaning closes the Modbus TCP port. When the port number is changed to 0, the change
takes effect when the G60 is restarted. When it is set to 0, use the front panel or serial port to communicate with the relay.

MMS CONNECTION TIMEOUT — This setting specifies a time delay for the detection of network TCP connection lost. If there is
no data traffic on the TCP connection for greater than the time specified by this setting, the connection is terminated. This
frees up the connection to be re-used by a client. A setting of 10 seconds disables this timer. The TCP connection then is
managed by a standard TCP KeepAlive message sequence. These messages are transmitted every 20 seconds when there
is no MMS communication between the relay and the client. If there are no responses to the TCP KeepAlive messages, the
connection is closed. For any change to this setting to take effect, restart the unit. The change takes effect for a new
connection. For any existing open connection when the change is made, close and re-open the connection. Cycling power

PRODUCT SETUP
CHAPTER 5: SETTINGS
The Distributed Network Protocol (DNP) allows for the optimization of control and data acquisition between the equipment
in the substation and the central control center. The protocol is scalable; that is, it is designed to be compatible with the
latest high speed LAN technology yet still be implemented over slower speed serial links.
The DNP improves upon many master-slave protocols by improving overall communication performance requirements
and provides time-stamping with millisecond accuracy.
The G60 supports the Distributed Network Protocol (DNP) version 3.0. DNP is enabled when the SETTINGS  PRODUCT SETUP
 COMMUNICATIONS  PROTOCOL setting is set to DNP 3.0. The G60 can be used as a DNP slave device connected to
multiple DNP masters (usually an RTU or a SCADA master station). Since the G60 maintains two sets of DNP data change
buffers and connection information, two DNP masters can actively communicate with the G60 at one time.
DNP is not available using the USB port on the graphical front panel.
See the UR Family Communications Guide for more information on DNP.
For any change to DNP settings, restart the relay.
The DNP Channels sub-menu is shown.

DNP CHANNEL 2 PORT:
NONE
Range: NONE, COM1 - RS485, COM2 - RS485, FRONT
PANEL - RS232, NETWORK - TCP
The DNP CHANNEL 1 PORT and DNP CHANNEL 2 PORT settings select the communications port assigned to the DNP protocol
for each channel. Once DNP is assigned to a serial port, DNP is the only protocol running on that port; Modbus or IEC
60870-5-103 are disabled. If DNP is assigned to RS485, the protocol must be set to DNP on the serial port configuration as
well, for the change to take effect. When the DNP CHANNEL 1(2) PORT setting is set to “Network - TCP,” the channel 1(2) DNP
protocol can be used over TCP/IP on the Ethernet ports. When this value is set to “Network - UDP,” the DNP protocol can be
used over UDP/IP on channel 1 only. The "Front Panel - RS232" setting does not apply to the graphical front panel; when
selected the DNP client cannot establish a connection on a USB port.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.
The DNP ADDRESS setting is the DNP slave address. This number identifies the G60 on a DNP communications link. Assign a
unique address to each DNP slave.
The G60 can specify a maximum of five clients for its DNP connections. These are IP addresses for the controllers to which
the G60 can connect. The settings follow.

The DNP TCP/UDP PORT NUMBER setting is for normal DNP operation. To close the port, set the port number to 0.
The DNP UNSOL RESPONSE FUNCTION is set to “Disabled” for RS485 applications since there is no collision avoidance
mechanism. The DNP UNSOL RESPONSE TIMEOUT sets the time the G60 waits for a DNP master to confirm an unsolicited
response. The DNP UNSOL RESPONSE MAX RETRIES setting determines the number of times the G60 retransmits an
5-54
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
unsolicited response without receiving confirmation from the master; a value of “255” allows infinite re-tries. The DNP
UNSOL RESPONSE DEST ADDRESS is the DNP address to which all unsolicited responses are sent. The IP address to which
solicited responses are sent is determined by the G60 from the current TCP connection or the most recent UDP message.
The DNP scale factor settings are numbers used to scale analog input point values. These settings group the G60 analog
input data into the following types: current, voltage, power, energy, power factor, and other. Each setting represents the
scale factor for all analog input points of that type. For example, if the DNP VOLTAGE SCALE FACTOR setting is set to “1000,”
all DNP analog input points that are voltages are returned with values 1000 times smaller (for example, a value of 72000 V
on the G60 is returned as 72). These settings are useful when analog input values must be adjusted to fit within certain
ranges in DNP masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (that is, the value is 10 times larger).
The DNP DEFAULT DEADBAND settings determine when to trigger unsolicited responses containing analog input data. These
settings group the G60 analog input data into the following types: current, voltage, power, energy, power factor, and other.
Each setting represents the default deadband value for all analog input points of that type. For example, to trigger
unsolicited responses from the G60 when any current values change by 15 A, the DNP CURRENT DEFAULT DEADBAND setting
is set to “15.” Note that these settings are the deadband default values. DNP object 34 points can be used to change
deadband values, from the default, for each individual DNP analog input point.
The DNP TIME SYNC IIN PERIOD setting determines how often the Need Time Internal Indication (IIN) bit is set by the G60.
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The DNP MESSAGE FRAGMENT SIZE setting determines the size, in bytes, at which message fragmentation occurs. Large
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to
be necessary, which provides more robust data transfer over noisy communication channels.
Check the “DNP Points Lists” G60 web page to view the analog inputs and/or binary inputs points lists. This page
can be viewed with a web browser by entering the IP address of the G60 Ethernet port employed to access the G60
Main Menu, then by clicking the Device Information Menu item, then the DNP Points Lists item.
The DNP OBJECT 1 DEFAULT VARIATION to DNP OBJECT 32 DEFAULT VARIATION settings select the DNP default variation
number for object types 1, 2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation response when variation
0 is requested and/or in class 0, 1, 2, or 3 scans. See the DNP Implementation section in the UR Family Communications
Guide.
The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a single
physical or virtual control point in an IED. In the G60 relay, DNP binary outputs are mapped to virtual inputs. However,
some legacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to
support the concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is,
the DNP master can operate a single point for both trip and close, or raise and lower, operations. The G60 can be
configured to support paired control points, with each paired control point operating two virtual inputs. The DNP NUMBER
OF PAIRED CONTROL POINTS setting allows configuration of 0 to 32 binary output paired controls. Points not configured as
paired operate on a one-to-one basis.
The DNP TCP CONNECTION TIMEOUT setting specifies a time delay for the detection of dead network TCP connections. If
there is no data traffic on a DNP TCP connection for greater than the time specified by this setting, the connection is
aborted by the G60. This frees up the connection to be re-used by a client.
For any change to DNP settings, restart the relay.

5.3.5.12 IEC 61850 protocol
The G60 is provided with optional IEC 61850 communications. This feature is specified as a software option at
the time of ordering. See the Order Codes section in chapter 2 for details.
The IEC 61850 settings are accessible in EnerVista software or a substation configuration language (SCL) generating tool.
The path is Settings > Product Setup > Communications > IEC 61850 or Settings > IEC 61850. The settings are not
accessible from the front panel of the device.
IEC 61850 messaging can form part of protection schemes. Consider IEC 61850 settings with the same criticality as
protection element settings. To ensure reliable performance of protection schemes utilizing IEC 61850 messaging,
route IEC 61850 traffic on a separate port from SCADA communications, or use redundant, independent ports, and
a high-speed network recovery method, such as PRP.

G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
Overview
IEC 61850 is a series of international standards and technical reports applicable to power utility automation systems. It
includes semantics, abstract communication services, specific communication services, performance specifications,
network engineering guidelines, configuration description methodologies, and engineering processes. The standard
enables interoperability among intelligent electronic devices (IEDs) from different suppliers and interoperability among
software configuration tools from different suppliers. Interoperability in this case is the ability for IEDs to operate on the
same network or communication path sharing information and commands, and for configuration tools to understand
each other's configuration files.
The UR family supports a large subset of IEC 61850 features. These are detailed in the UR Family Communications Guide
and include the information model, GOOSE publish, GOOSE subscribe, buffered report server, unbuffered report server, and
Manufacturing Message Specification (MMS) query, read, write, and control services. In addition, the URs and their
EnerVista UR Setup software support IEC 61850 Substation Configuration Language (SCL) file import/export and merging.
Whereas prior UR releases used edition 1.0 of IEC 61850, this release uses edition 2.0, with certain modifications according
to IEC/TR 61850-90-5. Only edition 2.0 61850 configuration tools can interoperate with edition 2.0 devices, such as the UR
7.3x release. This UR release uses edition 2.0 SCL, which differs from edition 1.0 SCL. GSSE, fixed GOOSE, and fixed report
services of previous releases are no longer supported, and thus UR devices of previous releases using these features have
to be converted to configurable GOOSE to communicate with a 7.3x or later device.
Many settings of UR protection, control, and monitoring elements, that is to say elements that are not concerned with the
IEC 61850 protocol, can nevertheless be accessed via IEC 61850. These settings are documented elsewhere in this Settings
chapter. This section of the Settings chapter deals solely with the settings that configure the IEC 61850 protocol itself.
The maximum number of simultaneous clients supported by the UR family is five.
EnerVista setup for IEC 61850
The EnerVista UR Setup software provides the interface to configure G60 settings for the IEC 61850 protocol. This section
describes this interface. The software also supports import/export and merging of IEC 61850 Substation Configuration
Language (SCL) files as documented in the UR Family Communications Guide.
The IEC 61850 protocol configuration settings cannot be accessed through the UR front panel and are instead accessible
with the EnerVista software, via MMS query, read, and write services, or via 61850 SCL file transfer. Accordingly, whereas
other settings are presented in this manual as they appear on the front panel, IEC 61850 settings are presented as they
appear in the software. See the UR Family Communications Guide for MMS and SCL access. Note that if you update the IEC
61850 settings in the EnerVista software by writing to them by MMS while the corresponding IEC 61850 panel is open in
EnerVista, you need to close then open the panel in EnerVista for the correct readings to display.
IEC 61850 protocol configuration settings are accessed through software panels that are selected either in the Online
Window area (see figure) or the Offline Window area in the EnerVista software.
The EnerVista software also includes an interface that is compatible with firmware versions 5.0 to 7.2 to configure
subscribers. Use the Simplified GOOSE Configurator in the Offline Window area.

Opening the IEC 61850 window while online causes the UR Setup software to retrieve and import an SCL file from the G60.
This System Configuration Description (SCD) file contains all the settings in the UR at the time of the file request, both those
that are mapped into the IEC 61850 information model (that is, the "public" sections) and those that are not in the model
(that is, the "private" section). The UR EnerVista Setup software imports all of these settings into the current session, not just
those in the IEC 61850 window. To avoid loss of any unsaved setting changes made in other panels during the current
session, all other panels for the G60 must be closed before the IEC 61850 panel can be opened, and the software prompts
for this when applicable. Panels for other devices can be open concurrently to facilitate parameter coordination.

CHAPTER 5: SETTINGS
PRODUCT SETUP
When CyberSentry security is enabled, editable settings depend on the user role logged in. For example, an Administrator
and Engineer can change settings. If prompted for a "Settings password," it means the Administrator or Engineer
password.
The Restore button restores settings in the window to their last saved values. The Default button reverts settings in the
window to factory default values or Oscillography, Data Logger, or FlexLogic Equation Editor pre-configured values. The
Reset button reverts all IEC 61850 settings to the factory default values, not just the current window. (In other settings
windows, the button reverts settings in the window to factory default values.)
When a setting is enabled, its panel continues to read Disabled until relaunched. There is no polling capability to update
automatically the IEC 61850 readings, so the panel needs to be closed then opened for the correct status to display. Good
practice is to close any panel not in use because changes being made by other users too are reflected only upon relaunch
of the panel.
Some of the IEC 61850 settings use floating point data, which guarantees accurate representation of real numbers up to
seven digits. Numbers with more than seven digits are approximated within a certain precision. This can result in
differences between what is entered and what is saved, and for example results in differences shown on a settings
comparison report.
Create CID and settings files
When the Save button is clicked in the online IEC 61850 window, UR Setup software prepares a configured IED description
(CID) file containing all the settings of the UR and sends the CID file to the G60. Upon receipt, the G60 checks the CID file for
correctness, going out of service, then back into service when the CID file is accepted. The software displays a message
when the G60 is running the new settings, confirming successful transfer. This process can take a minute or so due to the
amount of processing required by the software and the G60.
When the Save button is clicked in the offline IEC 61850 window, UR Setup software saves to local storage, for example the
hard drive, a .urs file containing all settings of the UR.
View IID/CID files
The file types are described as follows:
•
IID — Instantiated IED capability description file — Actual settings on UR
•
CID — Configured IED description file — Settings sent to the UR (may or may not contain the present settings)
IID and CID files are viewable. For example, after modifying settings in the IEC 61850 panels and clicking Developer IID/
CID Viewer in the software, a CID file generates and an SCL Viewer shows the updated CID file content. There are no edit
or save functions; use instead the Back Up and Restore Settings instructions later in this document to save the files.
Searches are case insensitive.

Server configuration
The Server Configuration panel contains IEC 61850 settings relevant to the server functions of the IED implementation.
The path is Settings > Product Setup > Communications > IEC 61850 > Server Configuration.
The following settings are available, where <iedName> is a syntactic variable representing the present value of the IED
NAME setting.
IED NAME
Range: 1 to 58 VisibleString characters
Default: TEMPLATE
The value entered sets the IED name used by IEC 61850 for the G60. An IED name unique within the network must be
entered for proper operation. Valid characters are upper and lowercase letters, digits, and the underscore (_) character.
The first character must be a letter.
The IED NAME and the Product LD inst name comprise the <LDName> for a product. The longest LD inst are "Master"
and "System" at six characters, with Master being fixed and the others configurable with the configurable Logical device
feature. So the IED NAME needs to be restricted to 58 characters to meet a 64 character limit.
Location
Range: 0 to 255 ASCII characters
Default: Location
The value entered sets the value of the data attribute <LDName>/LPHD1.PhyNam.location. This data attribute is
provided by the protocol to allow the user to declare where the equipment is installed.
5
Latitude
Range: -90.000 to 90.000 degrees in steps of 0.001 degree
Default: 0.000 deg
The value entered sets the value of the data attribute <LDName>/LPHD1.PhyNam.latitude. This data attribute is provided
by the protocol to declare the geographical position of the device in WGS84 coordinates -latitude. Negative values
indicate a southern latitude. WGS refers to the world geodetic system, which is used in global positioning systems (GPS),
and 84 is the current version of the standard.
Longitude
Range: -180.000 to 180.000 degrees in steps of 0.001 degree
Default: 0.000 deg
The value entered sets the value of the data attribute <LDName>/LPHD1.PhyNam.longitude. This data attribute is
provided by the protocol to declare the geographical position of the device in WGS84 coordinates -longitude. Negative
values indicate a western longitude.
Altitude
Range: 0 to 10,0000 m in steps of 1 m
Default: 0 m
The value entered sets the value of the data attribute <LDName>/LPHD1.PhyNam.altitude. This data attribute is provided
by the protocol to declare the geographical position of the device in WGS84 coordinates - altitude.
Prefix for GGIO1
Range: 0 to 11 VisibleString characters
Default:
This setting sets the LN Prefix of the FlexLogic operand interface logical node GGIO1 that is described in the GGIO1
section later. Valid characters are upper and lowercase letters, digits, and the underscore (_) character. The first
character must be a letter. UR Setup software does not allow entry of a prefix that duplicates any other GGIO1 prefix
that is used by the product, such as ConIn and ConOut.

later. Valid characters are upper and lowercase letters, digits, and the underscore (_) character. The first character must
be a letter. UR Setup software does not allow entry of a prefix that duplicates any other GGIO2 prefix that is used by the
product.
Prefix for GGIO4
Range: 0 to 11 VisibleString characters
Default:
This setting sets the LN Prefix of the FlexAnalog operand interface logical node GGIO4 that is described in the GGIO4
section later. Valid characters are upper and lowercase letters, digits, and the underscore (_) character. The first
character must be a letter. UR Setup software does not allow entry of a prefix that duplicates any other GGIO4 prefix
that is used by the product.
LLN0.Mod.ctlModel
Range: status-only, direct-with-normal-security, sbo-with-normal-security
Default: sbo-with-normal-security
This setting specifies the control service that clients must use to control the TEST MODE FUNCTION of the G60. An "on"
control to <LDName>/LLN0.Mod changes TEST MODE FUNCTION to Disabled, an "on-blocked" control changes it to Test,
and a "test/blocked" changes it to Test-Blocked.
Configuration Type
Range: G2, E3-2.0
Default: G2
This setting is read only. It specifies the method used to describe GOOSE subscription configuration in SCL. See the UR
Family Communications Guide for details. In the G2 mode, the CID file contains IED elements for IEDs subscribed to by
this IED containing GOOSE subscription information. In the E3 2.0 mode, the CID file has only one IED element and
GOOSE subscription information is coded in data objects in the standard LGOS logical node used to monitor reception of
the subscribed GOOSE. UR 7.30 or later accepts either mode. The set value is for the entire EnerVista installation and is
preserved between sessions. To change this global field, click File > Preferences and access the IEC 61850 panel; you do
not need to be connected to the device.

Each logical device has this setting. The value is fixed at "Master" in the first logical device and configurable in all others.
Valid characters are upper and lowercase letters, digits, and the underscore (_) character. The entered value sets the

Functional ldName
Range: 0 to 64 VisibleString characters
Default: empty string
Each logical device has this setting. The value is configurable in all logical devices. Valid characters are upper and
lowercase letters, digits, and the underscore (_) character. If the number of characters entered is greater than zero, the
setting sets the value of the function-related name used in communications. If an ldName is entered, it must form an
LDName that is unique within the network for proper operation. The standard recommends choosing this name
according to IEC 81346-1. If the number of characters entered is zero, no function-related name is defined.
Throughout the remainder of this IEC 61850 section, <LDName> is a syntactic variable representing the present
LDName of the master logical device. In other contexts LDName can refer to some other logical device. Depending
on its context, <LDName> can be a product-related name or a function-related name.
configRev
Range: 0 to 255 ASCII characters
Default:
This data attribute is provided by the protocol to declare changes to the semantic of the data model of the UR. The intent
is that the user changes Master configRev each time that the semantic or data model changes, so that clients can
readily detect the change. A semantic change is a logical node getting a new semantic use; for example, an instance of
logical node CSWI is now serving a different physical switch, or an instance of a logical node PDIS is now used for
another zone. A data model change is a change in the presence of logical nodes, data objects, data attributes, or
instance names.
The scope of Maser configRev is the entire relay configuration, as the Master logical device is the root logical device.
Similar settings are provided for the other logical nodes; the scope of these other configRev settings is limited to the
corresponding logical device configuration.
paramRev
Range: -2,147,483,648 to 2,147,483,647
Default: 0
The configurable data attribute paramRev has a scope that includes the entire device, and thus is modified whenever
any setting in the device changes. The UR increments the value of paramRev by one whenever one or multiple setting
changes occurs in one Modbus write request by any means (front panel, Modbus, or MMS) other than by SCL file

download. Incrementing occurs whether or not the setting is represented in the information model. When a UR device or
EnerVista UR Setup accepts an SCL file, paramRev is set to the value in that SCL file. When EnerVista UR Setup changes
one or more settings, and prepares an SCL file, it increments paramRev to the next higher multiple of 10 000.
Each logical device has a name: LDName. (Note the upper case LD.) LDName has both a product-related form and
a function-related form as per IEC 61850 6:2009 8.5.3.
SCL files invariably use the product-related form of LDName. The product-related form is the concatenation of the
IED name of the device and the individual logical device's inst name. The IED name is the value of the "IED NAME"
setting on the Server Configuration panel, and the logical device inst names are each the value of the
corresponding "Product LD inst name" setting here. The "Product LD inst name" of the first logical device is fixed at
"Master".
Communications use the function-related form of LDName if a function-related name is defined, otherwise
communications use the product-related name. The function-related name is the value of the corresponding
"Functional ldName" setting if this setting is not empty, if empty the function-related name is not defined.
In SCL, the function-related name is specified by the LDevice element attribute ldName (note the lower case ld).
Absence of this attribute indicates the function-related name is not defined. In SCL the product-related name is
specified by the name attribute of the IED element and the inst attribute of the LDevice element.
In the right pane, logical nodes assigned permanently to the Master logical device and LLN0 in all logical devices are
greyed-out as shown earlier. These are not movable. Any other logical node can be dragged to any of the logical devices in
the middle pane, which causes that logical device to be re-assigned to that logical device. Right-clicking a logical node
device displays a menu that lists the logical devices that this logical node can be moved to. Clicking one of these re-assigns
the logical node. Other common keyboard and/or mouse action can be used to select one or more logical nodes and move
the selected nodes together.

Support for Routable GOOSE
Routable GOOSE (R-GOOSE) is supported in firmware release 7.4 and later. Routable GOOSE allows UR and other devices to
be located in separate networks. Encryption/decryption of messages is performed by a separate gateway device.
Messages are routed using a separate router, using IP addresses.
Note the following behavior:
•
A v7.4 device can send an R-GOOSE message to another v7.4 device when both have R-GOOSE active as the protocol

R-GOOSE is available through the IEC 61850 software option. If R-GOOSE security is required, the CyberSentry
software option also must be purchased.
TxGOOSE
IEC 61850 GOOSE is an efficient method for simultaneous high-speed delivery of generic substation event information by a
publishing device to more than one subscribing device. A TxGOOSE is a UR element implementing a single IEC 61850
GOOSE message publishing service. The subscribing function in URs is performed by RxGOOSE elements, as described in
the next section. Each UR with IEC 61850 order code options has 16 TxGOOSE elements. Each TxGOOSE can either use the
original format specified in IEC 61850 8 1:2011 or the routable GOOSE (R-GOOSE) format specified in IEC TR 61850-905:2012. Each TxGOOSE element can publish the values of up to 64 attributes of the IEC 61850 nodes in the UR.
Published TxGOOSE messages configured in the EnerVista UR Setup software can be subscribed by and the published
operand values understood by other UR devices. Furthermore, they can be subscribed to and understood by any device of
any manufacturer that implements the IEC 61850 edition 1.0 or 2.0 GOOSE subscription mechanism. The messages are
published with a multicast address so that the network sends the messages to all devices; any number of devices that
want to subscribe can.
For wide area protection, control, and monitoring schemes, R-GOOSE wraps the proven original format GOOSE in IP/UDP to
multicast (or unicast) the data over a Wide Area Network (WAN). Sample applications are Wide area Remedial Action
Scheme (RAS) and Under Voltage/ Frequency Load Shedding Schemes (UVLS/UFLS). R GOOSE uses IGMPv3 (Internet Group
Management Protocol version-3, RFC 3376) for multicasting.
The entities whose values are published in GOOSE messages are known as members. The members are itemized in an
ordered list known as a data set. Each TxGOOSE can use any one of the configured data sets. (See the DataSets section
later for details.) The performance of a TxGOOSE is determined by its dataset. Booleans in fast GOOSE datasets are
designed for the TT6 transfer time class (3 ms), while Booleans in the Normal datasets are designed for the TT3 class (100
ms). Due to the significant amount of CPU time required to compose a TT6 TxGOOSE message and the limited amount of
time allowed by the TT6 class, at most four of these can be configured in a given UR. So only four fast GOOSE are allowed
to be configured, and the UR software has a check to disallow the use of more than four fast datasets in GOOSE. If six fast
datasets are configured outside of UR software and the file sent directly to the relay, the relay rejects the file. The design
does allow six fast datasets to be used in report control blocks, which allows fast scanned data in reports.
Each enabled TxGOOSE transmits its message whenever a value change is detected in one or more of its members. If the
changed value is a Boolean in a fast dataset, then the change detect occurs in the TT6 detection time of 3 ms or less. If the
member is an analog value in a fast dataset, the change detect occurs in the TT3 time of 100 ms. In Normal GOOSE
Datasets, change detection for all dataset members occurs in the TT3 time of 100 ms. To guard against the possibility that
such a message is lost in the network before it reaches all subscribers, the message is quickly retransmitted several times.
To allow subscribers to verify that their link to the publisher and the publisher itself are healthy, each message is also
retransmitted periodically even while the values are unchanging. These latter messages are known as heartbeat
messages, while the former are known as event messages. Heartbeat messages also provide means for a subscriber
newly online to receive the published values in the absence of an event.
The details of TxGOOSE message construction are contained in the UR Family Communications Guide. Knowledge of these
details is not required to configure GOOSE.
The UR does not implement the Fixed-Length encoded GOOSE messages option specified in IEC 61850-8-1:2011 clause
A.3; the UR always uses the ASN.1 Basic encoding rules (as specified in ISO/IEC 8825-1) as specified in IEC 61850 edition 1.0
and as optional in IEC 61850 edition 2.0.

TxGOOSE1 MODE
Range: Disabled, GOOSE, R-GOOSE
Default: Disabled
When set to Disabled, TxGOOSE1 messages are not published. When set to GOOSE, TxGOOSE1 messages are published
in IEC 61850 8 1:2011 GOOSE format. When set to R-GOOSE, TxGOOSE1 messages are published in Routable GOOSE

TxGOOSE1 GoID
Range for Edition 2: 0 to 129 Visible String characters
Range for Edition 1: 0 to 65 Visible String characters
Default: TxGOOSE1
The entered value sets the goID value published in TxGOOSE1 messages, and can be used by subscribers to discriminate
the TxGOOSE1 messages from other GOOSE messages.
TxGOOSE1 DatSet
Range: None, TT6DataSet1,TT6 DataSet2, … TT3DataSet01,TT3 DataSet02, …
Default: None
This setting selects the published data set using the UR Setup software designator for the data set. If None is selected, no
TxGOOSE1 messages are sent.
The IEC 61850 name of the data sets are configured in the Datasets panel, as described later.
Some datasets are designed for the TT6 transfer time class (3 ms), while others are designed for the TT3 class (100 ms).
The performance of a TxGOOSE is determined by its dataset. Use TT6 datasets for trips and blocking applications, TT3
datasets for slow automatic interactions. The 61850 name of the datasets are configured in the Datasets panel.
An ObjectReference to the data set, which consists of the concatenation of the string "<LDName>/LLN0." and the data
set name, is published in the datSet field of TxGOOSE1 messages and can be used by subscribers to discriminate
TxGOOSE1 messages from other GOOSE messages. <LDName> is a syntactic variable that is set to the value of setting
Master functional ldName if one or more characters have been entered to that setting, otherwise the value of setting IED
NAME suffixed with "Master".
To configure a DataSet, select it at the top of the window from the drop-down list. In the lower part of the window, drag
and drop configuration items to the right side. Dataset members configured here affect other Report or TxGOOSE control
blocks that use the same DataSet.
The performance of the TxGOOSE is determined by the performance of the selected dataset. When the selection is
TT3DataSet01, TT3DataSet02, … it is possible that transient events can be missed.
TxGOOSE1 DST MAC
Range: any 12 digit hexadecimal number
Default: 01-0C-CD-01-00-00
When the TxGOOSE1 MODE setting is R-GOOSE, the TxGOOSE1 DST MAC address is set to 00 00 00 00 00 00 and cannot be
changed. Otherwise, the value entered here sets the Ethernet destination Media Access Control (MAC) address in
published TxGOOSE1 messages. As the standard requires that the address have the multicast bit set TRUE, that is to say
the second digit is set to an odd number, messages transmitted have the multicast bit set TRUE no matter its value in this
setting.
The destination MAC address can be used by the network to restrict message delivery to selected devices that need to
receive them, reducing network load. This address also can be used by hardware in receiving devices to filter out
messages that are of no interest to them, reducing processor burden. Different filtering algorithms are implemented by
different devices. The standard recommends that the algorithm used by hardware of the receiving device be considered
when assigning destination multicast addresses.
Subscribers can use this address to discriminate TxGOOSE1 messages from other GOOSE messages.
TxGOOSE1 VLAN PRIORITY
Range: 0, 1, 2, 3, 4, 5, 6, 7, 5-4, 6-4, 6-5, 7-4, 7-5, 7-6
Default: 4
When the value entered is 0, 1, 2, 3, 4, 5, 6, or 7, the User Priority value in the IEEE 802.1Q VLAN tag included in published
TxGOOSE1 messages is set to that value. When one of the two-digit values is entered, the dynamic priority feature is
selected: the first event message has the User Priority value of the first digit, and User Priority is decremented in each
following message until reaching the value of the second digit. For instance, if the selected value is 7-5, then the User
Priority values in successive messages beginning with the message triggered by an event is 7, 6, 5, 5, 5, 5, 5, and so on.
Do not make a dynamic priority selection when standard behavior is required.
Network devices can forward a message with a higher priority value before a message with a lower priority value, which
speeds delivery of high-priority messages in heavily loaded networks. The standard recommends that higher-priority
messages, such as GOOSE, have priority values in the range of 4 to 7.

TxGOOSE1 VLAN ID
Range: 0 to 4095 in steps of 1
Default: 0
The value entered sets the VID value in the IEEE 802.1Q VLAN tag included in published TxGOOSE1 messages. VID can be
used by network devices to direct messages to only selected devices, reducing network burden. VID values of 0 and 1
are assigned by IEEE 802.1Q to other functions and are not to be used for GOOSE.
TxGOOSE1 ETYPE APPID
Range: 0 to 65535 in steps of 1
Default: 0
The value entered sets the APPID value in published GOOSE messages and can be used by subscribers to discriminate
TxGOOSE1 messages from other GOOSE messages.
The standard reserves the value range 0 to 16383 for GOOSE Type 1 (Fast messages), and reserves the value range
32768 to 41151 for GOOSE Type 1A (Trip messages). Some subscribers can process messages in the Type 1A range
faster than messages in the Type 1 range. The standard reserves the default value (0) to indicate lack of configuration.
The standard strongly recommends unique, source-orientated APPIDs within a given system.
TxGOOSE1 CONFREV
Range: 0 to 4294967295 in steps of 1
Default: 1
The entered value sets the confRev value in published GOOSE messages and can be used by subscribers to discriminate
TxGOOSE messages of the expected configuration revision from messages of a different revision. The standard requires
that CONFREV be incremented each time the members or the order of the members published is changed. The standard
states that the value of 0 is reserved.

TxGOOSE1 RETRANS TIME
Range: 0 to 100 ms in steps of 1 ms
Default: 4 ms
If the entered time is non-zero, when a member value change is detected, four event transmissions are sent, then
heartbeat transmissions resume. The interval between the first and second event transmissions, and between the
second and third, is the time set here. The interval between the third and the fourth event transmission is double the set
time. If the entered time is zero, only a single event transmission occurs, then heartbeat transmissions resume.
TxGOOSE1 TIME TO LIVE
Range: 1 to 300 s in steps of 1 s
Default: 300 s
The value entered sets the timeAllowedtoLive value in published TxGOOSE1 messages. The standard requires
subscribers to assume a failure has occurred when another TxGOOSE1 message is not received within the published
timeAllowedtoLive time.
Base this setting on the TxGOOSE UPDATE TIME and the tolerable number of contiguous message delivery misses. For
example, if the heartbeat time is 10 s, and missing up to three successive messages is tolerable, make the setting
10 * 3 + 1 = 31 s. The extra second is to ensure that arrival of the third heartbeat transmission beats the
timeAllowedtoLive timer.
TxGOOSE1 UPDATE TIME
Range: 1 to 60 s in steps of 1 s
Default: 60 s
This setting specifies the time interval between heartbeat messages, meaning messages that are sent periodically while
no events are detected.

TxGOOSE1 PORT ASSIGNMENT
Range: Disabled, Port-1; Port-2; Port-3; Ports-1,2; Ports-2,3; Ports-1,3; Ports-1,2,3
Default: Ports-1,2,3
This setting specifies the Ethernet ports for transmission of TxGOOSE1. When set to disabled, TxGOOSE1 messages are
not transmitted on any port no matter the state of GoEna. When set to Port-1, TxGOOSE1 is published over Ethernet
Port-1 only; while selecting Ports-1, 3 option, the same TxGOOSE1 is published to both Ports 1 and 3; and similarly if set
to Ports-1,2,3, all ports publish TxGOOSE1.
When setting PRT2 REDUNDANCY to Failover or to PRP, the TxGOOSE 1 port assignment needs to be set to ports 2
and 3 (Ports-2,3).
Also, Port 3 configuration in the CID file is ignored. The Port 3 ConnectedAP elements has no meaning, as ports 2
and 3 use the port 2 MAC address, IP address, and mask.
R-TxGOOSE1 IP CLASS
Range: 0 to 256 in steps of 1
Default: 46
This setting applies to IEC 61850 Edition 2.
When the TxGOOSE1 MODE setting is other than R-GOOSE, the value of this setting is not used. Otherwise this setting
selects the IPv4 Differentiated Services Code Point-DSCP (formerly called TypeOfService-TOS) value. This value provides
priority routing, when supported in the routers. The default value is for Expedited Forwarding (101110B, 46 or 2EH).
R-TxGOOSE1 DST IP
Range: 0.0.0.0 to 255.255.255 in steps of 1
Default: 224.0.0.0
When the TxGOOSE1 MODE setting is other than R-GOOSE, the value of this setting is not used. Otherwise this setting
specifies destination IP address for the R-TXGOOSE1 that is entered in Standard IPV4 address format. The destination IP
address needs to be a valid multicast or unicast IP address. The value specified in this setting is mapped to IPv4 header
32 bit field for Destination IP Address while publishing R-GOOSE1.
The default IP address 224.0.0.0 is reserved, and hence not a valid multicast IP address.
The source IP address is that of the UR port from which the R-GOOSE messages are transmitted.
R-TxGOOSE1 SECURITY
Range: None, Signature, Signature and Encryption
Default: None
This setting applies to IEC 61850 Edition 2.
This setting specifies level of security (authentication/encryption) used for TxGOOSE1. None specifies no security
mechanisms are to be used. Signature specifies only signature (no encryption) is to be used. SignatureAndEncryption

GOOSE messages from any device of any manufacturer that implements the IEC 61850 edition 1.0 or 2.0 GOOSE publish
service or the 61850-90-5 R GOOSE service can be subscribed to. The UR accepts both the variable-length encoded GOOSE
messages specified in IEC 61850 8 1:2004 and the fixed-length encoded GOOSE messages as specified in IEC 61850 8
1:2011 clause A.3.
Each enabled RxGOOSE monitors for interruption of the GOOSE messages it subscribes to based on the value in the
timeAllowedtoLive field of the last message received. If a new message is not received within that time interval, the
RxGOOSE assumes that connectivity is lost. FlexLogic operands (for example RxGOOSE1 On, RxGOOSE1 Off) reflect the
status of each RxGOOSE connectivity. An RxGOOSE connection is also considered lost after the UR finishes restart until a
message is received. While any RxGOOSE connectivity is lost, a common RxGOOSE Fail self-test is activated.
Messages that contain the value true in the ndsCom field are never accepted. Messages that contain the value true in the
simulation field (test field in Edition 1.0 messages) are accepted only when the UR Test Mode Function setting is set to Test

publisher is a UR 7.3x series device, <GoCBName> is "GoCB" suffixed with the two digit TxGOOSE instance number, for
example "GoCB01". If the publisher is a UR 7.40 series device, <GoCBName> is as specified earlier in the TxGOOSE
section of this chapter.
RxGOOSE1 datSet
Range: 0 to 32 alphanumeric and underscore characters, beginning with an alpha character
Default: empty string
If the entered value has one or more characters, the datSet field of incoming GOOSE messages must exactly match this
value prefixed by <LDName>/LLN0$ for the message to be accepted as a valid RxGOOSE1 message. <LDName> is as
specified in the RxGOOSE GoCBRef setting above. If the entered value is the empty string, RxGOOSE1 does not check the
value received in the datSet field.

CHAPTER 5: SETTINGS
If the publisher is a UR 7.3x series device, set this setting to the value of the publisher's DataSetxx name setting, where xx
is the instance number of the data set selected by the publisher's TxGOOSE datSet setting. If the publisher is a UR 7.40
series device, datSet is as specified in the DataSets section of this chapter.
RxGOOSE1 ConfRev
Range: 0 to 4294967295 in steps of 1
Default: 1
If the value entered is non-zero, the confRev field of incoming GOOSE messages must exactly match this value for the
message to be accepted as a valid RxGOOSE1 message. If the entered value is zero, RxGOOSE1 does not check the value
received in the confRev field.
If the publisher is a UR 7.3x series device, set this setting to match the value of the publisher's TxGOOSE ConfRev setting.
R-RxGOOSE1 RECEPTION MODE
Range: SSM, ASM, Unicast
Default: SSM
This setting applies to IEC 61850 Edition 2.
When the RxGOOSE1 MODE setting is other than R-GOOSE the value of this setting is not used. Otherwise it selects the
R-GOOSE reception mode.
R-RxGOOSE RECEPTION MODE specifies the R-RxGOOSE DST IP range. When set to SSM, R-RxGOOSE DST IP must be in
the range of 232.0.0.1 to 232.255.255.255. When set to ASM, R-RxGOOSE DST IP must be in the range of 224.0.0.1 to
239.255.255.255, excluding the SSM range. Note that the SSM range is inside the ASM range and therefore the ASM use
excludes the SSM range. The default destination IP address 224.0.0.0 is reserved, and hence not a valid multicast IP
address.
5
The reception modes are related to Layer-3 R-GOOSE reception from routers/WAN. The subscription to multicasting of RGOOSE is supported using IGMP Protocol Independent Multicast (PIM). It is made available in either Source Specific
Multicast (SSM) mode or Any Source Multicast (ASM) mode. Unicast (over UDP) mode can also be used. In case of
multicasting (IGMPv3 based SSM or ASM), the R-GOOSE subscriber device requests the Last Hop Router (LHR) to
subscribe to a specific multicasting group.
If the publisher is using a unicast destination IP address for this R-GOOSE, then set R-RxGOOSE1 RECEPTION MODE to
Unicast. Otherwise set R-RxGOOSE1 RECEPTION MODE to the SSM or ASM mode used by the local routers/firewalls.
R-RxGOOSE1 SRC IP
Range: 0.0.0.0 to 255.255.255 in steps of 1
Default: 127.0.0.1
This setting applies to IEC 61850 Edition 2.
When the RxGOOSE1 MODE setting is other than R-GOOSE, the value of this setting is not used. When the RxGOOSE1
MODE setting is R-GOOSE and the R-RxGOOSE RECEPTION MODE setting is ASM, the value of this setting is not used.
Otherwise the Source IP Address field of incoming R-GOOSE messages must exactly match this value for the message to
be accepted as a valid RxGOOSE1 message. Set this setting to the value of the source IP address used by the publisher.
For UR publishers, this value is in setting PRT# IP ADDRESS.
The UR does not validate the address entered. The default IP address 127.0.0.1 is a reserved, not a valid IP address. Enter
a valid IP source address.
R-RxGOOSE1 DST IP
Range: 0.0.0.0 to 255.255.255 in steps of 1
Default: 224.0.0.0
This setting applies to IEC 61850 Edition 2.
When the RxGOOSE1 MODE setting is other than R-GOOSE, the value of this setting is not used. Otherwise the
Destination IP Address field of incoming R GOOSE messages must exactly match this value for the message to be
accepted as a valid RxGOOSE1 message. Set this setting to the same value as the R-GOOSE publisher's Destination IP
Address. For UR publishers, this value is in setting R-TxGOOSE# DST IP.
The destination IP address needs to be a valid multicast or unicast IP address. The UR does not validate the address
entered. The default IP address 224.0.0.0 is reserved, and hence not a valid multicast IP address.

R-RxGOOSE1 SECURITY
Range: None, Signature, Signature and Encryption
Default: None
This setting applies to IEC 61850 Edition 2.
This setting specifies the level of security (authentication/encryption) used for RxGOOSE1. None indicates no security
mechanisms are in use. Signature indicates only signature (no encryption) is in use. SignatureAndEncryption indicates
that both signature and encryption are in use. Normally this setting is set to match the GOOSE publisher's security
method.
RxGOOSE1 Member 1
Range: End of List, BOOLEAN, FLOAT32, INT32, Dbpos (DPS), Quality, TimeStamp
Default: End of List
This setting specifies the type that the first member of incoming GOOSE messages must be for the message to be
accepted as a valid RxGOOSE1 message. There are similar settings for each of the up to 64 members that the UR is able
to subscribe to in a given GOOSE message. The member before the first member setting set to "End of List" must be the
last member of the message for the message to be accepted as a valid RxGOOSE1 message.
If the publisher is a UR 7.3x or 7.40 series device, set these settings to match the basic type of the members of the
publisher's data set selected by the publisher's TxGOOSE datSet setting.
If the publisher dataset includes members with structured data, that is, data attributes, sub-data objects, and/or data
attributes with sub-data attributes, configuration must use one of the new 7.40 UR Setup RxGOOSE Inputs pages. In this
case the Member setting displays as the product-related name used by the publishing IED of the data object or data
attribute, in standard SCSM format (e.g. Publisher1LD1/LLN0$ST$Off$stVal).
Note that a dataset can hold at most 64 basic data attribute values, and that a single structured data object or attribute
can contain multiple basic data attribute values. UR Setup software does not allow more that 64 basic data attribute
values to be entered, in which case the last several members settings cannot be changed from End of List.
Note that the publisher's name alone does not contain all the information required for subscription, additional publisher
information model information is stored elsewhere. For this reason, manual entry of the name is not supported.
RxGOOSE inputs
The values received by RxGOOSE elements need to be converted to FlexLogic or FlexAnalog operands so that they can be
used by other UR elements. This conversion is done by RxGOOSE Boolean, RxGOOSE DPS, and RxGOOSE Analog elements.
Each RxGOOSE Boolean can convert the value of a specified Boolean value received by a specified RxGOOSE to a FlexLogic
operand. Each RxGOOSE DPS can convert the value of a specified Dbpos (Double bit position) value to four FlexLogic
operands, one for each of the four possible Dbpos states. Each RxGOOSE Analog can convert the value of a specified
FLOAT32 member to a FlexAnalog operand. Each of these operands reverts to its default state when the RxGOOSE
connectivity is lost. Other types of values can be present in subscribed GOOSE messages, but cannot be converted to
operands. An RxGOOSE Input that is mapped to a value that in the GOOSE message is a child of a data object reverts to its
configured default value while the Quality value in that data object is invalid, and also while the Quality value is test and
this relay's TEST MODE FUNCTION setting is other than Test or Test-Blocked.
RxGOOSE Boolean, RxGOOSE DPS, and RxGOOSE Analog elements are mapped to various data objects in
<iedName>Master/GGIO3. This is to allow reading of their values via MMS and to allow references to them in SCL files.
GGIO3 has no settings, nor is it visible in the UR Setup software. See the UR Family Communications Guide for more
information on GGIO3.

Most of the settings are configured by drag-and-drop. However the ID, DEFAULT STATE, and EVENTS settings must be
individually entered when the factory default values are not acceptable.
RxGOOSE Boolean1 ID
Range: 0 to 20 characters
Default: RxG Bool1
This setting allows the user to assign descriptive text to the name of the RxGOOSE Boolean1 FlexLogic operand. The full
operand name is the value of this setting appended with " On". The basic and enhanced front panels display the first 17
characters of this setting plus " On" to fit the 20 character display.
RxGOOSE Boolean1 RxGOOSE
Range: None, RxGOOSE1, RxGOOSE2, and so on
Default: None
This setting selects the RxGOOSE containing the value that drives the RxGOOSE Boolean1 FlexLogic operand. If set to
None, the RxGOOSE Boolean1 FlexLogic operand assumes its default state.
RxGOOSE Boolean1 Member
Range: 1 to 64 in steps of 1
Default: 1
This setting selects the GOOSE message member that drives the RxGOOSE Boolean1 FlexLogic operand. A setting of 1
selects the first member, 2 selects the second member, and so on. Entering a number greater than the number of
members in the message and entering the number of a member which does not contain a BOOLEAN results in the
RxGOOSE Boolean1 FlexLogic operand assuming its default state. The Subscribed to column identifies the particular
Boolean subscribed to even if the member is a structure containing more than one Boolean.
RxGOOSE Boolean1 DEFAULT STATE
Range: On, Off, Latest/On, Latest/Off
Default: Off
This setting selects the logic state for the RxGOOSE Boolean1 FlexLogic operand if the UR has just completed startup and
the selected RxGOOSE has not yet received a message, or the selected RxGOOSE has lost its connectivity with the
publisher. The following choices are available:

RxGOOSE DPS1 Member
Range: 1 to 64 in steps of 1
Default: 1
This setting selects the GOOSE message member that drives the RxGOOSE DPS1 FlexLogic operand. A setting of 1 selects
the first member, 2 selects the second member, and so on. Entering a number greater than the number of members in
the message and entering the number of a member that is not a Dbpos results in the RxGOOSE DPS1 FlexLogic operand
assuming its default state. In the case that the member is a structure containing more than one Dbpos, the Subscribed

RxGOOSE DPS1 DEFAULT STATE
Range: Intermediate-state, Off, On, Bad-state, Latest
Default: Latest
This setting selects the logic state for the data attribute @Master/GGIO3.IndPos01.stVal and the DPS FlexLogic operands
when the UR has just completed start-up and the selected RxGOOSE has not yet received a message, and when the
RxGOOSE has lost its connection with the publisher. When this setting is selected to Latest, the value of @Master/
GGIO3.IndPosψψ.stVal is Intermediate-state when the UR has just completed start-up and the selected RxGOOSE has
not yet received a message, and the latest received value when the RxGOOSE loses its connectivity with the publisher.
RxGOOSE DPS1 EVENTS
Range: Disabled, Enabled
Default: Disabled
This setting selects whether Off to On transitions of the RxGOOSE DPS1 FlexLogic operands are recorded by the event

RxGOOSE Analog1 ID
Range: 0 to 20 characters
Default: RxG Analog1
This setting allows the user to assign descriptive text to RxGOOSE Analog1. Unlike RxGOOSE Booleans and RxGOOSE DPS,
the RxGOOSE Analog operands have fixed names, for example RxGOOSE Analog1.
RxGOOSE Analog1 RxGOOSE
Range: None, RxGOOSE1, RxGOOSE2, and so on
Default: None
This setting selects the GOOSE message that drives the RxGOOSE Analog1 FlexAnalog operand. If set to None, the
RxGOOSE Analog1 FlexAnalog operand assumes its default state.
RxGOOSE Analog1 Member
Range: 1 to 64 in steps of 1
Default: 1
This setting selects the GOOSE message member that drives the RxGOOSE Analog1 FlexAnalog operand. A setting of 1
selects the first member, 2 selects the second member, and so on. Entering a number greater than the number of
members in the message and entering the number of a member that does not contain a FLOAT32 results in the
RxGOOSE Analog1 FlexAnalog operand assuming its default state. The Subscribed to column identifies the particular
FLOAT32 subscribed to even if the member is a structure containing more than one FLOAT32.
RxGOOSE Analog1 DEFAULT
Range: -1000000.000 to 1000000.000 in steps of 0.001
Default: 1000.000
This setting specifies the value of the GOOSE analog input when the selected RxGOOSE has lost its connectivity with the
publisher and the RxGOOSE Analog1 DEFAULT MODE is set to "Default Value." Otherwise this setting has no effect. This
setting is stored as an IEEE 754 / IEC 60559 floating point number. Because of the large range of this setting, not all
possible values can be stored. Some values can be rounded to the closest possible floating point number.
RxGOOSE Analog1 DEFAULT MODE
Range: Default Value, Last Known
Default: Default Value
When the selected RxGOOSE has lost its connectivity with the publisher and this setting is "Last Known," the value of the
RxGOOSE Analog1 FlexLogic operand remains at the last received value. When the selected RxGOOSE has lost its
connectivity with the publisher and this setting value is "Default Value," then the RxGOOSE Analog1 FlexLogic operand is
defined by the RxGOOSE Analog1 DEFAULT setting. After restart, until a message is received, the operand value is the
default value.
RxGOOSE Analog1 UNITS
Range: up to 4 characters
Default: empty string
This setting specifies a four-character string that is used in the actual values display of RxGOOSE Analog1.
RxGOOSE Analogs are floating-point values, with no units. The RxGOOSE UNIT and PU base settings allow the user to
configure RxGOOSE Analog, so that it can be used in a FlexElement.
RxGOOSE Analogs that represent current, voltage, power, frequency, angles, or power factor can be used in a
FlexElement. The following text must be used in the UNITS setting, to represent these types of analogs: A, V, W, var, VA,
Hz, deg, and no text (blank setting) for power factor.
RxGOOSE Analogs can be compared to other RxGOOSE Analogs with any character string or no string.
RxGOOSE Analog1 PU Base in kilo
Range: 0.000 to 1000000000.000 in steps of 0.001
Default: 1.000
This setting specifies the per-unit base value for other G60 features to use with the RxGOOSE Analog1 operand. A
FlexElement for instance subtracts two quantities after converting their values to integers rescaled to a common base,
the common base being the largest of the base values of the two quantities. If one of quantities is RxGOOSE Analog1 and
its per-unit base value is not appropriate, the rescaling operation can result in unnecessary loss of precision or overflow

in the integer result. The FlexElement Base Units table in the Settings > FlexLogic > FlexElements section later, which
tabulates the per-unit base value used by its pickup setting and implies the per-unit base used by other FlexAnalogs, can
be of use in selecting a value for the RxGOOSE Analog1 PU setting.
Some UR elements have requirements for the type of input operands, for instance current type or voltage type. These
elements assume that RxGOOSE Analog operands are of whatever type is necessary to meet these requirements.
The per-unit base setting represents thousands, not single units. For example, a PU base of 1.000 is actually 1000 and a
PU base of 0.001 is 1.
When using RxGOOSE Analogs and PU base in FlexElements, the largest value that can be displayed in the FlexElement
actual values is 2,140,000.000.

An IEC 61850 Report server is an efficient method to deliver generic substation event information from a single server to a
single client, such as a supervisory control IED. A Configurable Report is a UR element implementing an IEC 61850 Report
server, either of the buffered or unbuffered kind. The following table lists the number of Configurable Report elements. Each
Configurable Report element can report the values of up to 64 FlexLogic or FlexAnalog operands. Buffered report elements
queue value changes that occur while the client is offline and delivered when the client re-connects. Up to 512 events can
be queued. Unbuffered control blocks purge all value change events when the connection to the client is lost; any events
that occur while the client is not connected are lost.

Configurable Reports interoperate with any client device of any manufacturer that conforms to the IEC 61850 edition 1.0
or 2.0 report client requirements.
The entities whose values are reported by a Configurable Report are known as members. The members are itemized in an
ordered list known as a data set. Each Configurable Report can use any one of the data sets provided.
Each enabled Configurable Report transmits an update to its client whenever a value change is detected in one or more of
its members. Also, the control block can be configured to send integrity reports containing the present value of all
members either on demand from the client or periodically. A TCP handshaking mechanism causes messages that are not
read and acknowledged by the client to be retransmitted.

CHAPTER 5: SETTINGS
For a Configurable Report to operate, its members must be selected (that is, its data set configured) and a client must open
a connection to, configure, and enable its report control block. Control blocks and data sets can be pre-configured by
sending the G60 a CID file. See the UR Family Communications Guide for details. EnerVista UR Setup also can be used to
select the data set members and to pre-configure the control blocks.
Each buffered report has the following settings.
Buffered Report1 RptID
Range: 0 to 129 VisibleString characters
Default: empty string
The name of the report. The entered value sets the RptID value in Buffered Report1 messages, and it can be used by the
client to discriminate Buffered Report1 messages from other messages. If the number of characters entered is zero, the
value used for RptID in messages is an ObjectReference to the report's control block, that is, "<LDName>/
LLN0$BR$"BRCB01".
Buffered Report1 Name

This setting selects the data set whose members' status is reported in Buffered Report1 messages using the UR Setup
software designator for the data set. The IEC 61850 name of the data sets are configured in the Datasets panel, as
described later.
An ObjectReference to the data set, which consists of the concatenation of the string "<LDName>/LLN0$" and the data
set name, is used in the datSet field of report messages, and it can be used by the client to discriminate Buffered
Report1 messages from other messages.
The performance of the report is determined by the performance of the selected dataset. When the selection is
TT3DataSet01, TT3DataSet02, … it is possible that transient events can be missed.
To configure a DataSet, select it at the top of the window from the drop-down list, for example DataSet02 shown in the
previous figure. In the lower part of the window, drag and drop configuration items to the right side. For example select
the ST Ind001 stVal item and drag it to DataSet Member 1. Dataset members configured here affect other Report or
TxGOOSE control blocks that use the same DataSet.
Buffered Report1 ConfRev
Range: 0 to 4294967295 in steps of 1
Default: 1
The entered value sets the confRev value in Buffered Report1 messages, and it can be used by clients to discriminate
report messages of the expected configuration revision from messages of a different revision. The standard requires
that confRev be incremented each time the members or the order of the members is changed, and each time the data
set name is changed. The standard states that the value of 0 is reserved.

CHAPTER 5: SETTINGS
PRODUCT SETUP
As mentioned in the preceding GOOSE and Reports sections, the members whose values are communicated by these
services are itemized in an ordered list known as a data set. Each UR with the IEC 61850 option has 18 data sets (six fast
and 12 slow). Each data set can contain as many as 64 members. Any data set can be used simultaneously by any number
of TxGOOSE elements and/or by any number of Configurable Report elements. UR Setup software can configure any
FlexLogic operands and any FlexAnalog operands as members.
Figure 5-34: IEC 61850 DataSets
5
UR Setup software requires data set members to be IEC 61850 data objects or data attributes with Functional Constraint
ST or MX. Certain FlexLogic and FlexAnalog operands have factory-assigned data attributes as tabulated in the UR Family
Communications Guide. All FlexLogic and FlexAnalog operands can be user-assigned to GGIO1 or GGIO4 data attributes,
so that operands without factory-assigned data attributes can still have their values published. See the GGIO1 and GGIO4
sections later for details.
Datasets used by TxGOOSE1, TxGOOSE2, and/or by reports also provide a chatter suppression service for their Boolean
members. Oscillation in a value, also known as chatter, can be caused by errors in logic programming, inadequate
hysteresis (deadband) on a threshold, or a failed station component. Chatter can flood a communications network with
GOOSE messages, degrading response time for all users. If chatter is detected in a Boolean member, TxGOOSE suspends
GOOSE event message triggering and report message triggering from that member for as long as the condition exists, and
for a minimum period of one second. While sending is suspended, a self-test message identifying the specific data item
detected as oscillating is activated.
For a summary of the panels in which the data sets are used, the path is Settings > Product Setup > Communications >
IEC 61850 > DataSets > Summary.
For the settings, navigate to Settings > Product Setup > Communications > IEC 61850 > DataSets > TT6DataSet1 for the
first data set.
Copy and paste functions are available when right-clicking a DataSet. They allow the target dataset to be configured
based on its order code. If some dataset items are not supported, they are not pasted, and a warning message shows a list
of dataset items that were not supported and not pasted. The DataSet name is not copied or pasted. In short, use this
feature to copy a DataSet Member setting and paste it into another Member setting, a text file, or Word, as examples.

This setting is a deadband setting and is used by the relay to determine when to update the "mag" and "cVal" values
from the associated "instMag" and "instCVal" values. The value shall represent the percentage of difference between
maximum and minimum in units of 0.001%. The minimum and maximum values for TmnsDelta data object are
-500000000 ns and 500000000 ns respectively and for example, a setting value of 0.002% results in the dead banded
value of (500000000 - (-500000000)) * 0.002 / 100 = 20000 ns. The default setting value of 0.000% does not update the
"mag" and "cVal" values.
Deadband settings
A deadband is a range in which no action occurs, usually expressed as a percentage.
The IEC 61850 panels contain hundreds of deadband settings, such as in the following panels: Product Setup > Real Time
Clock, FlexLogic, Control Elements, and GGIO4. Each panel is not outlined here.
Deadband setting names all end either with "DB" or .db. As they all work the same way, but each on a different analog
value, a single description applicable to all deadband settings is given here. The analog value that each deadband setting
applies is usually obvious from the name of the setting. However, a tabulation of the analog values and their associated
deadband setting can be found in the UR Family Communications Guide.

G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS

Figure 5-38: Deadband settings with .db suffix
GOOSE, buffered report, and unbuffered report messages are for the most part transmitted only when there is a value
change in one or more of their members. Most analog values continuously dither by an amount that is not significant.
Were a report to be sent each time an insignificant analog value change occurred, then the communications network
floods with GOOSE and report messages, degrading response time for all users.
To control this, a deadband setting is provided for each analog value. Also, in addition to the present actual value of each
analog ("instMag" in the following figure), there is a deadbanded value ("mag" in the figure), which is updated with the
present value only when the difference between the two exceeds the deadband setting (db in the figure). Changes to this
deadbanded value trigger transmissions when included in GOOSE and report data sets.
Figure 5-39: Deadband settings
Deadband settings are entered in UR Setup software in units of percent of the difference between the "max." and "min." of
the associated analog value. A zero deadband setting suppresses transmission triggering. The range of deadband settings
is 0.000 to 100.000% in steps of 0.001. The default value is 0.000%.
GGIO4 elements have individual settings for "min." and "max." The min. and max. for FlxEIGAPC#.OpSig.db (FLEXELEMENT #
OpSig) are -50 pu and +50 pu respectively. The min. value for all other quantities is 0. The max. values are as follows:
•
Phase current — 46 x phase CT primary setting

GGIO4 is a UR feature that allows up to 32 UR FlexAnalog operands to be user-mapped to an IEC 61850 information model
data attribute.
For the value of a FlexAnalog operand to be read via MMS, included in TxGOOSE messages, or included in buffered/
unbuffered reports, the value must be assigned to a data attribute. GGIO4 allows those FlexAnalog operands that have not
yet been factory-assigned to a data attribute to be user-assigned to a generic data attribute, and thus have their values
included in IEC 61850 communications.
Navigate to Settings > Product Setup > Communications > IEC 61850 > GGIO > GGIO4 > GGIO4.AnIn1 to access the
settings for the first GGIO4 value. The settings and functionality for the others are similar.

IEC 60870-5-104 is a transmission protocol for network access, specifically for communication between a control station
and substation over a TCP/IP network.
5
The G60 supports the IEC 60870-5-104 protocol. This protocol is enabled when the SETTINGS  PRODUCT SETUP 
COMMUNICATIONS  PROTOCOL setting is set to IEC 60870-5-104. The G60 can be used as an IEC 60870-5-104 slave device
connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the G60 maintains two
sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the G60 at one
time.
The IEC ------- DEFAULT THRESHOLD settings are used to determine when to trigger spontaneous responses containing
M_ME_NC_1 analog data. These settings group the G60 analog data into types: current, voltage, power, energy, and other.
Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to trigger
spontaneous responses from the G60 when any current values change by 15 A, the IEC CURRENT DEFAULT THRESHOLD
setting is set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of measured
value, short floating point value) points can be used to change threshold values, from the default, for each individual
M_ME_NC_1 analog point. Whenever power is removed and re-applied to the G60, the default thresholds are in effect.
The IEC REDUNDANCY setting decides whether multiple client connections are accepted or not. If redundancy is set to Yes,
two simultaneous connections can be active at any given time.
IEC TCP PORT NUMBER — To close the port, set the port number to 0. Any change takes effect when the G60 is restarted.

The G60 is provided with optional Ethernet Global Data (EGD) communications capability. This feature is
specified as a software option at the time of ordering. See the Order Codes section in chapter 2 for details.
Ethernet Global Data (EGD) is a suite of protocols used for the real-time transfer of data for display and control purposes.
The relay can be configured to ‘produce’ EGD data exchanges, and other devices can be configured to ‘consume’ EGD data
exchanges. The number of produced exchanges (up to three), the data items in each exchange (up to 50), and the
exchange production rate can be configured.
The relay supports one fast EGD exchange and two slow EGD exchanges. There are 20 data items in the fast-produced
EGD exchange and 50 data items in each slow-produced exchange.
EGD cannot be used to transfer data between UR series relays. The relay supports EGD production only. An EGD exchange
is not be transmitted unless the destination address is non-zero, and at least the first data item address is set to a valid
Modbus register address. The default setting value of “0” is considered invalid.
Fast exchanges (50 to 1000 ms) are generally used in control schemes. The G60 has one fast exchange (exchange 1) and
two slow exchanges (exchange 2 and 3).

Slow EGD exchanges (500 to 1000 ms) are generally used for the transfer and display of data items. The settings for the
fast and slow exchanges are as follows.
EXCH 1 DESTINATION — This setting specifies the destination IP address of the produced EGD exchange. This is usually
unicast or broadcast.
EXCH 1 DATA RATE — This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms, the
exchange data is updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data is updated and sent
once per second. EGD exchange 1 has a setting range of 50 to 1000 ms. Exchanges 2 and 3 have a setting range of 500 to
1000 ms.
EXCH 1 DATA ITEM 1 to 20/50 — These settings specify the data items that are part of this EGD exchange. Almost any data
from the G60 memory map can be configured to be included in an EGD exchange. The settings are the starting Modbus
register address for the data item in decimal format. See the Modbus memory map in the UR Series Communications
Guide for details. The Modbus memory map display shows addresses in hexadecimal format. Convert these hex values to
decimal format before entering them as values for these setpoints.
5
To select a data item to be part of an exchange, it is only necessary to choose the starting Modbus address of the item.
That is, for items occupying more than one Modbus register (for example, 32 bit integers and floating point values), only the
first Modbus address is required. The EGD exchange configured with these settings contains the data items up to the first
setting that contains a Modbus address with no data, or 0. That is, if the first three settings contain valid Modbus addresses
and the fourth is 0, the produced EGD exchange contains three data items.

The G60 is provided with optional IEC 60870-5-103 communications capability. This feature is specified as a
software option at the time of ordering. See the Order Codes section in chapter 2 for details.
IEC 60870-5-103 is a companion standard to the IEC 60870-5 suite of standards for transmission protocols. It defines
messages and procedures for interoperability between protection equipment and devices of a control system in a
substation for communicating on a serial line.
The IEC 60870-5-103 protocol is enabled when the SETTINGS  PRODUCT SETUP  COMMUNICATIONS  PROTOCOL setting
is set to IEC 60870-5-103.
The IEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serial communication, exchanging
information with a control system. In the context of this protocol, the protection equipment is the slave and the control
system is the master. The communication is based on a point-to-point principle. The master must be able to interpret the
IEC 60870-5-103 communication messages.

The UR implementation of IEC 60870-5-103 consists of the following functions:
•
Report binary inputs
•
Report analog values (measurands)
•
Commands
•
Time synchronization
The RS485 port supports IEC 60870-5-103.
The UR Family Communications Guide contains more information on the protocol.
IEC103 COMMON ADDRESS OF ASDU — This setting uniquely defines this G60 on the serial line. Select an ID between 0 and
254. This ID does not need to be in sequential order for all stations that communicate with a controller, but it is
recommended. Note that RS485 only allows a maximum of 32 slave stations on a communication line, so the entire range
of 254 addresses is never exhausted.
IEC103 SYNC TIMEOUT — This setting defines the time that the G60 waits for a synchronization message. The G60
synchronizes its clock using all available sources, with the source synching more frequently overwriting the time of the
other sources. Since the synchronization message received from the IEC 60870-5-103 master is less frequent than IRIG-B,
PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs
and none of IRIG-B, PTP, or SNTP is active, the G60 sets the invalid bit in the time stamp of a time-tagged message.
The settings for the remaining menus are outlined as follows.

The binary input points are sent as Class 1 data. They are sent either as a response to a general interrogation received
from the controller or reported spontaneously. Spontaneous transmission occurs as a response to cyclic Class 2 requests.
If the G60 wants to transmit Class 1 data at that time, it demands access for Class 1 data transmission (ACD=1 in the
control field of the response).
For any change to take effect, restart the relay.

The configuration menu allows a maximum of four ASDUs containing measurands.
Measurands are sent as a response to Class 2 requests, which are cyclic requests coming from the master.
TYPE IDENTIFICATION (TYP) — The configuration field TYP indicates how many measurands are present in the corresponding
ASDU. Each ASDU can take either 4 or 9 measurands maximum, depending on the type identification (3 respectively 9). For
any change to take effect, restart the relay.
FUNCTION TYPE (FUN) and INFORMATION NUMBER (INF) — These two fields form the Information Object Identifier of the ASDU
as defined in IEC 60870-103. For any change to take effect, restart the relay.
SCAN TIMEOUT (SCAN TOUT) — This is the cyclic period used by the G60 to decide when a measurand ASDU is included in a
response. The measurand is sent as response to a Class 2 request when the corresponding timeout expires. The default
value 0 means 500 ms.
ANALOG # — This field contains the actual measurand to be sent in the response to the master. The measurands can be
mapped using elements from a list of FlexAnalog operands. The measurands sent are voltage, current, power, power
factor, and frequency. If any other FlexAnalog is chosen, the G60 sends 0 instead of its value. Note that the power is
transmitted in KW, not W. Measurands are transmitted as ASDU 3 or ASDU 9 (type identification value set to measurands I,
respectively measurands II).
Each IEC 60870-5-103 measurands list ends at the first unconfigured ("Off") value. Any measurand assigned after the first
"Off" value is ignored.
At least one measurand per ASDU must be configured in order to configure the following ASDU. For example, the user can
configure only one measurand for each ASDU, but the user is not allowed to skip ASDU 2 and configure measurands in
ASDU 3.
For any change to take effect, restart the relay.
ANALOG # FACTOR and OFFSET — For each measurand included in the ASDU, a factor and offset also can be configured. The
factor and offset allow for scaling to be performed on measurands. The final measurement sent to the IEC 60870-103
master is then "a*x + b," where x is the measurand, a is the multiplying factor and b is the offset. The master has to perform
the reversed operation in order to retrieve the actual value if such scaling is done. By default a = 1 and b = 0, so no scaling
is done if these values are left at their defaults. Examples of when scaling is appropriate are as follows:
•
If the measured value contains decimals and it is important to preserve the resolution. Since the format for
transmitting the measurand does not permit decimals, a factor a>1 can be applied before transmission. For example,
a frequency F=59.9Hz can be transmitted as Ft = 10 * F = 10 * 59.9 = 599. In this case a = 10, b = 0. The master receives
599 and has to divide by 10 to retrieve the real value 59.9.
•
If the measured value is larger than what fits in the format defined in IEC 103. The format defined in the standard
allows for signed integers up to 4095. By offsetting, unsigned integers up to 4096 + 4095 = 8191 are supported.
Scaling using factors <1 can be required in such cases. The calculation is outlined in the IEC 60870-5-103 chapter of
the UR Family Communications Guide. Two examples follow, where you decide factors a and b.
Example 1: Nominal power Pn = 100 MW = 100000 KW (power is transmitted in KW)
Since P can be both positive and negative:
Transmitted power Pt = (4095/(Pn*2.4)) * P = (4095/(100000 * 2.4) ) * P
= 0.017 * P
a = 0.017
b=0

PRODUCT SETUP
CHAPTER 5: SETTINGS
Pt = 0.017 * P
For a max power 100000 KW * 2.4 = 240000 KW, we transmit
Pt = 0.017 * 240000 = 4080
A value above 240 MW is indicated by overflow.
Example 2: Nominal voltage Vn = 500000 V
Since RMS voltage V can be only positive:
Transmitted voltage Vt = (8191/(Vn*2.4)) * V - 4096 =
= (8191/(500000 * 2.4) ) * V - 4096 = 0.0068 * V - 4096
a = 0.0068
Since the step is in increments of 0.001, we round it at:
a = 0.006
b = -4096
Vt = 0.006 * V - 4096
For max voltage 500000 V * 2.4 = 1200000 V, we transmit
Vt = 0.006 * 1200000 - 4096 = 7200 - 4096 = 3104

The relay contains a real time clock (RTC) to create time stamps for communications protocols as well as for historical data,
such as event records and oscillography. When the relay restarts, the RTC initializes from an onboard battery-backed
clock, which has the same accuracy as an electronic watch, approximately ±1 minute per month (~23 ppm). Once the RTC
is synchronized with the Precision Time Protocol (PTP), IRIG-B, or SNTP, its accuracy approaches that of the synchronizing
time delivered to the relay. While the RTC is not synchronized via PTP or IRIG-B, or the relay determines that it has an offset
possibly greater than 10 µs from the international time standard, the CLOCK UNSYNCHRONIZED FlexLogic operand is
activated.
The SYNCHRONIZING SOURCE setting displays in the software when the relay includes the IEEE 1588 software option. The
setting configures the priority sequence of the time synchronization source, to determine which of the available external
time sources to use for time synchronization. A setting of None causes the RTC and the synchrophasor clock to free-run,
and the clock can be changed from the front panel or from communications protocols. A setting of PP/IRIG-B/PTP/Other,
IRIG-B/PP/PTP/Other, or PP/PTP/IRIG-B/Other causes the relay to track the first source named that is enabled and
operational, or free-run if none of these are available. Here, PP means a time source that is strictly compliant with PP, PTP
means a time source that is not strictly compliant with PP, and Other means any less precise source (SNTP, IEC 103, IEC
104, Modbus, or DNP). When a time source fails or recovers, the relay automatically transfers synchronization as required
by this setting.
When the relay does not have the IEEE 1588 software option and this setting does not display, it uses IRIG-B when enabled
and operational, then failing that SNTP when configured and operational, and otherwise it free-runs unless the clock is
changed from the front panel or from communications protocols.
Setup for IRIG-B is illustrated in the Installation chapter.
For the Other protocols, whenever a time synchronization message is received through any of the active protocols, the
G60 clock updates. However, given that IEC 60870-5-103, IEC 60870-5-104, Modbus, and DNP are low-accuracy time
synchronization methods, avoid their use for synchronization when better accuracy time protocols, such as IRIG-B and
PTP, are active in the system. If IRIG-B or PTP is used to update the relay clock, the other protocols (such as SNTP) are not
allowed to update, even if active.
See the COMMANDS  SET DATE AND TIME menu section of this manual to manually set the RTC.
The REAL TIME CLOCK EVENTS setting allows changes to the date and/or time to be captured in the event record. The event
records the RTC time before the adjustment. A Date/Time Changed event is generated when:
•
The real time clock changed from SNTP/PTP/IRIG-B and the time difference is more than one second
•
The real time clock changed from the front panel or via Modbus register. The relay always generates this event
regardless of the time difference.
•
The Daylight Saving Time (DST) setting gets enabled and the current relay time is already in the DST zone
•
The real time clock enters or leaves DST

To enable IRIG-B synchronization, the input IRIG-B SIGNAL TYPE must be set to DC Shift or Amplitude Modulated. IRIG-B
synchronization can be disabled by making this setting None. When IRIG-B is enabled and active, clock synchronization by
communication protocols. (DNP, IEC 60870-5-103, IEC 60870-5-104) is blocked, and clock synchronization from the front
panel and over Modbus is always enabled.
Clocks can be synchronized locally among several relays using the computer time. When using a time source, such as
IRIG-B, the time is overwritten eventually by the time source. To synchronize clocks among UR devices:
1.
In the EnerVista software, expand the main menu in the Online Window area and select the Synchronize Devices
entry. The window opens. The software prompts to acknowledge any offline devices.
2.
Click the Synchronize Devices button at the top of the window, and confirm the action at the prompt. The devices
assume the time of the computer being used.

The G60 is provided with optional Precision Time Protocol capability. This feature is specified as the IEEE 1588
software option at the time of ordering. See the Order Codes section in chapter 2 for details.
The G60 supports the Precision Time Protocol (PTP) specified in IEEE Std 1588 2008 using the Power Profile (PP) specified in
IEEE Std C37.238 2011. This enables the relay to synchronize to the international time standard over an Ethernet network
that implements PP.
The relay can be configured to operate on some PTP networks that are not strictly PP. Time accuracy can be less than
specified for a PP network. Tolerated deviations from strict PP include 1) missing declaration of PP compliance in the
messages, 2) connection to a network device that does not support the PTP peer delay mechanism, 3) jitter substantially
greater than 1 µs in received event messages, and 4) certain non-compliant announce and sync message update rates.
The relay implements PTP according to IEEE Std 1588 2008 and the equivalent IEC 61588:2009(E), sometimes referred to as
version 2 PTP. It does not support the previous version of the standard (version 1).
PTP is a protocol that allows multiple clocks in a network to synchronize with one another. It permits synchronization
accuracies better than 1 ns, but this requires that each and every component in the network achieve very high levels of
accuracy and a very high baud rate, faster than normally used for relay communications. When operating over a generic
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
5-111
PRODUCT SETUP
CHAPTER 5: SETTINGS
Ethernet network, time error can amount to 1 ms or more. PP is a profile of PTP which specifies a limited subset of PTP
suitable for use in power system protection, control, automation, and data communication applications, and thereby
facilitates interoperability between different vendor’s clocks and switches. PP specifies a worst-case delivered time error of
less than 1 µs over a 16-hop network.
In a PTP system and in a PP system, the clocks automatically organize themselves into a master-slave synchronization
hierarchy with the “best” clock available making itself the "grandmaster" at the top of the hierarchy; all others make
themselves “slaves” and track the grandmaster. Typically the grandmaster clock receives its time from GPS satellites or
some other link to the international time standard. If the grandmaster fails, the next “best” clock available in the domain
assumes the grandmaster role. When a clock on start-up discovers that it is “better” than the present grandmaster, it
assumes the grandmaster role and the previous grandmaster reverts to slave. The G60 qualification mechanism accepts a
potential master clock as a new grandmaster, when in a four-second interval it has received three announce messages
from it, all better than the present grandmaster clock and better than any other announce in this interval.
Time messages issued by the grandmaster are delayed as they pass through the network both due to the finite speed of
the signal in the interconnecting fiber or wire, and due to processing delays in the Ethernet switches. Each clock and switch
implementing PP measures the propagation delay to each of its PP neighbors, and compensates for these delays in the
time received. Each network device implementing PP measures the processing delay it introduces in each time message
and compensates for this delay in the time it transmits. As a result, the time delivered to end-devices such as the UR are
virtually identical to the grandmaster time. If one of the network devices in the hierarchy does not fully implement PP, the
associated propagation delay and/or latency may not be compensated for, and the time received at the end-device can be
in error by more than 100 µs.
See the preceding Real Time Clock section for a description of when time values received via PTP are used to update the
relay’s real time clock.

The following settings are available for configuring the relay for PTP. The PTP menu displays only when the option was
purchased.
STRICT POWER PROFILE — Power profile (IEEE Std C37.238 2011) requires that the relay only select a power profile compliant
clock as a grandmaster, that the delivered time have worst-case error of ±1 µs, and that the peer delay mechanism be
implemented. With the strict power profile setting enabled, the relay only selects as master the clocks displaying the
IEEE_C37_238 identification codes. It uses a port only when the peer delay mechanism is operational. With the strict power
profile setting disabled, the relay uses clocks without the power profile identification when no power profile clocks are
present, and uses ports even if the peer delay mechanism is non-operational. This setting applies to all of the relay’s PTP
capable ports.
PTP DOMAIN NUMBER — Set this setting to the domain number of the grandmaster-capable clock(s) to be synchronized to. A
network can support multiple time distribution domains, each distinguished with a unique domain number. More
commonly, there is a single domain using the default domain number zero.
This setting applies to all of the relay’s PTP capable ports.
PTP VLAN PRIORITY — This setting selects the value of the priority field in the 802.1Q VLAN tag in request messages issued
by the relay’s peer delay mechanism. In compliance with PP the default VLAN priority is 4, but it is recommended that it be
set to 7 in accordance with PTP. Depending on the characteristics of the device to which the relay is linked directly, VLAN
Priority can have no effect.
This setting applies to all of the relay’s PTP capable ports.
PTP VLAN ID — This setting selects the value of the ID field in the 802.1Q VLAN tag in request messages issued by the relay’s
peer delay mechanism. It is provided in compliance with PP. As these messages have a destination address that indicates
they are not to be bridged, their VLAN ID serves no function, and so can be left at its default value. Depending on the
characteristics of the device to which the relay is linked directly, VLAN ID can have no effect. This setting applies to all of
the relay’s PTP capable ports.
PORT 1 ... 3 FUNCTION — While this port setting is selected to disabled, PTP is disabled on this port. The relay does not
generate or listen to PTP messages on this port.
PORT 1 ... 3 PATH DELAY ADDER — The time delivered by PTP is advanced by the time value in this setting prior to the time
being used to synchronize the relay’s real time clock. This is to compensate to the extent practical for time delivery delays
not compensated for in the network. In a fully compliant PP network, the peer delay and the processing delay mechanisms
compensate for all the delays between the grandmaster and the relay. In such networks, make this setting zero.
5-112
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
PRODUCT SETUP
In networks containing one or more switches and/or clocks that do not implement both of these mechanisms, not all
delays are compensated, so the time of message arrival at the relay is later than the time indicated in the message. This
setting can be used to approximately compensate for this delay. However, as the relay is not aware of network switching
that dynamically changes the amount of uncompensated delay, there is no setting that always and completely corrects
for uncompensated delay. A setting can be chosen that reduces the worst-case error to half of the range between
minimum and maximum uncompensated delay, if these values are known.
PORT 1 ... 3 PATH DELAY ASSYMMETRY — This setting corresponds to “delayAsymmetry” in PTP, which is used by the peer delay
mechanism to compensate for any difference in the propagation delay between the two directions of a link. Except in
unusual cases, the two fibers are of essentially identical length and composition, so make this setting zero.
In unusual cases where the length of the link is different in different directions, set this setting to the number of
nanoseconds the Ethernet propagation delay to the relay is longer than the mean of path propagation delays to and from
the relay. For instance, if it is known say from the physical length of the fibers and the propagation speed in the fibers that
the delay from the relay to the Ethernet switch it is connected to is 9000 ns and that the delay from the switch to the relay
is 11000 ns, then the mean delay is 10000 ns, and the path delay asymmetry is 11000 - 10000 = +1000 ns.

The G60 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the G60 can obtain clock time over
an Ethernet network. The G60 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a dedicated
product using a GPS receiver. UR family relays support unicast, broadcast, multicast, and anycast SNTP functionality.
The SNTP FUNCTION setting enables or disables the SNTP feature on the G60.
To use SNTP in unicast mode, set SNTP SERVER IP ADDR to the SNTP/NTP server IP address. Once this address is set and SNTP
FUNCTION is “Enabled,” the G60 attempts to obtain time values from the SNTP/NTP server. Since many time values are
obtained and averaged, it generally takes three to four minutes until the G60 clock is closely synchronized with the SNTP/
NTP server. It takes up to two minutes for the G60 to signal an SNTP self-test error if the server is offline.
To use SNTP in broadcast mode, set the SNTP SERVER IP ADDR setting to “0.0.0.0” and SNTP FUNCTION to “Enabled.” The G60
then listens to SNTP messages sent to the “all ones” broadcast address for the subnet. The G60 waits up to 18 minutes
(>1024 seconds) without receiving an SNTP broadcast message before signaling an SNTP self-test error.
The SNTP UDP PORT NUMBER is 123 for normal SNTP operation. The change takes effect when the G60 is restarted.
After enabling and waiting for the synchronization, verify that there is no SNTP Failure message in the Event Records.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.

The G60 maintains two times: local time and Universal Coordinated Time (UTC). Local time can be provided by IRIG-B
signals. UTC time is provided by SNTP servers.
The real-time clock (RTC) and time stamps reported in historical records and communication protocols can be incorrect if
the Local Time settings are not configured properly.
See the IRIG-B section in the Installation chapter for guidance on these settings when using an IRIG-B source that sets the
IRIG-B control bits according to IEEE Std 1344-1995.
LOCAL TIME OFFSET FROM UTC — Used to specify the local time zone offset from UTC (Greenwich Mean Time) in hours. Time
5
zones in the eastern hemisphere have positive values; time zones in the western hemisphere have negative values. A value
of zero causes the relay to use UTC for local time. This setting has two uses. When the system RTC is synchronized with a
communications protocol providing only local time or it is free-running, the offset setting is used to calculate UTC from the
local time these provide. When the RTC is synchronized with a communications protocol providing only UTC (such as PTP or
SNTP), the time offset setting is used to determine local time from the UTC provided. PTP
ALTERNATE_TIME_OFFSET_INDICATOR TLVs are not used to calculate local time.
DAYLIGHT SAVINGS TIME and DST — Can be used to allow the relay to follow the DST rules of the local time zone. Note that
when IRIG-B time synchronization is active, the local time in the IRIG-B signal contains any daylight savings time offset and
so the DST settings are ignored. Note that the following items do not include the DST: Time of Day Timer Start Time; Time

When enabled, this function monitors the pre-fault trigger. The pre-fault data are stored in the memory for prospective
creation of the fault report on the rising edge of the pre-fault trigger. The element waits for the fault trigger as long as the
pre-fault trigger is asserted, but not shorter than 1 second. When the fault trigger occurs, the fault data is stored and the
complete report is created. If the fault trigger does not occur within 1 second after the pre-fault trigger drops out, the
element resets and no record is created.
The user programmable record contains the following information: the user-programmed relay name, detailed firmware
revision (x.xx, for example) and relay model (G60), the date and time of trigger, the name of pre-fault trigger (a specific
FlexLogic operand), the name of fault trigger (a specific FlexLogic operand), the active setting group at pre-fault trigger, the
active setting group at fault trigger, pre-fault values of all programmed analog channels (one cycle before pre-fault trigger),
and fault values of all programmed analog channels (at the fault trigger).
Each fault report is stored as a file to a maximum capacity of ten files. An eleventh trigger overwrites the oldest file. The
EnerVista software is required to view all captured data. A FAULT RPT TRIG event is automatically created when the report
is triggered.
The relay includes two user-programmable fault reports to enable capture of two types of trips (for example, trip from
thermal protection with the report configured to include temperatures, and short-circuit trip with the report configured to
include voltages and currents). Both reports feed the same report file queue.
The last record is available as individual data items via communications protocols.
PRE-FAULT 1 TRIGGER — Specifies the FlexLogic operand to capture the pre-fault data. The rising edge of this operand stores
one cycle-old data for subsequent reporting. The element waits for the fault trigger to actually create a record as long as
the operand selected as PRE-FAULT 1 TRIGGER is “On.” If the operand remains “Off” for 1 second, the element resets and no
record is created.
FAULT 1 TRIGGER — Specifies the FlexLogic operand to capture the fault data. The rising edge of this operand stores the
data as fault data and results in a new report. The trigger (not the pre-fault trigger) controls the date and time of the
report.
FAULT REPORT 1 # 1 to FAULT REPORT 1 #32 — These settings specify an actual value such as voltage or current magnitude,
true RMS, phase angle, frequency, temperature, and so on, to be stored when the report is created. Up to 32 channels can
be configured. Two reports are configurable to cope with variety of trip conditions and items of interest.

Oscillography records contain waveforms captured at the sampling rate as well as other relay data at the point of trigger.
Oscillography records are triggered by a programmable FlexLogic operand. Multiple oscillography records can be captured
simultaneously.
When EnerVista UR Setup creates a new settings file, a Smart defaults feature automatically enters a basic oscillography
configuration. The basic configuration changes the factory default values to make the number of samples per cycle 32,
adds a selection of digital and analog channels that are often of interest, and adds a FlexLogic equation to trigger
oscillography. Review and update this basic configuration as required for the application at hand.
The NUMBER OF RECORDS is selectable, but the number of cycles captured in a single record varies considerably based on
other factors, such as sample rate and the number of operational modules. There is a fixed amount of data storage for
oscillography; the more data captured, the less the number of cycles captured per record. See the ACTUAL VALUES 

TRIGGER MODE — A new record automatically overwrites an older record when TRIGGER MODE is set to “Automatic
Overwrite.”
TRIGGER POSITION — Set this to a percentage of the total buffer size (for example, 10%, 50%, 75%, and so on). A trigger
position of 25% consists of 25% pre- and 75% post-trigger data.

virtual output, and so on). The relay sampling rate is 64 samples per cycle.
AC INPUT WAVEFORMS — Determines the sampling rate at which AC input signals (that is, current and voltage) are stored.
Reducing the sampling rate allows longer records to be stored. This setting has no effect on the internal sampling rate of
the relay, which is always 64 samples per cycle. That is, it has no effect on the fundamental calculations of the device.

These settings select the metering actual value recorded in an oscillography trace. The length of each oscillography trace
depends in part on the number of parameters selected here. Parameters set to “Off” are ignored. The parameters available
in a given relay depend on
•
the type of relay,
•
the type and number of CT/VT hardware modules installed, and
•
the type and number of analog input hardware modules installed
A list of all possible analog metering actual value parameters is presented in Appendix A: FlexAnalog Parameters. The
parameter index number shown in any of the tables is used to expedite the selection of the parameter on the relay display.
It can be time-consuming to scan through the list of parameters via the relay keypad and display — entering this number
via the relay keypad causes the corresponding parameter to display.
All eight CT/VT module channels are stored in the oscillography file. The CT/VT module channels are named as follows:
<slot_letter><terminal_number>—<I or V><phase A, B, or C, or 4th input>
The fourth current input in a bank is called IG, and the fourth voltage input in a bank is called VX. For example, F2-IB
designates the IB signal on terminal 2 of the CT/VT module in slot F.
If there are no CT/VT modules and analog input modules, no analog traces appear in the file; only the digital traces appear.
The source harmonic indices appear as oscillography analog channels numbered from 0 to 23. These correspond directly
to the to the 2nd to 25th harmonics in the relay as follows:
Analog channel 0 2nd harmonic
Analog channel 1  3rd harmonic

The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data can
be downloaded to EnerVista UR Setup and displayed with parameters on the vertical axis and time on the horizontal axis.
All data is stored in non-volatile memory, so the information is retained when power to the relay is lost.
For a fixed sampling rate, the data logger can be configured with a few channels over a long period or a larger number of
channels for a shorter period. The relay automatically partitions the available memory between the channels in use. The

Changing any setting affecting data logger operation clears data in the log.
DATA LOGGER MODE — This setting configures the mode in which the data logger operates. When set to “Continuous,” the
data logger actively records any configured channels at the rate as defined by the DATA LOGGER RATE. The data logger is
idle in this mode when no channels are configured. When set to “Trigger,” the data logger records any configured channels
at the instance of the rising edge of the DATA LOGGER TRIGGER source FlexLogic operand. The data logger ignores all
subsequent triggers and continues to record data until the active record is full. Once the data logger is full, a CLEAR DATA
LOGGER command is required to clear the data logger record before a new record can be started. Performing the CLEAR
DATA LOGGER command also stops the current record and resets the data logger to be ready for the next trigger.
DATA LOGGER TRIGGER — This setting selects the signal used to trigger the start of a new data logger record. Any FlexLogic
operand can be used as the trigger source. This setting only applies when the mode is set to “Trigger.”

Note: for calculation using method 2a
The relay measures current demand on each phase, and three-phase demand for real, reactive, and apparent power.
Current and Power methods can be chosen separately for the convenience of the user. Settings are provided to allow the
user to emulate common electrical utility demand measuring techniques, for statistical or control purposes. If the CRNT
DEMAND METHOD is set to "Block Interval" and the DEMAND TRIGGER is set to “Off,” Method 2 is used as follows. If DEMAND
TRIGGER is assigned to any other FlexLogic operand, Method 2a is used as follows.
The relay can be set to calculate demand by any of the following three methods.
5.3.11.1 Calculation method 1: Thermal exponential
This method emulates the action of an analog peak-recording thermal demand meter. The relay measures the quantity
(RMS current, real power, reactive power, or apparent power) on each phase every second and assumes that the circuit
quantity remains at this value until updated by the next measurement. It calculates the 'thermal demand equivalent'
based on the following equation:
Eq. 5-6
where
d = demand value after applying input quantity for time t (in minutes)
D = input quantity (constant)
k = 2.3 / thermal 90% response time
The figure shows the 90% thermal response time characteristic of 15 minutes. A setpoint establishes the time to reach
90% of a steady-state value, just as the response time of an analog instrument. A steady state value applied for twice the
response time indicates 99% of the value.

CHAPTER 5: SETTINGS
Figure 5-50: Thermal demand characteristic
5.3.11.2 Calculation method 2: Block interval
This method calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over
the programmed demand time interval, starting daily at 00:00:00 (that is, 12:00 am). The 1440 minutes per day is divided
into the number of blocks as set by the programmed time interval. Each new value of demand becomes available at the
end of each time interval.
5.3.11.3 Calculation method 2a: Block interval (with start demand interval logic trigger)
This method calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over
the interval between successive Start Demand Interval logic input pulses. Each new value of demand becomes available at
the end of each pulse. Assign a FlexLogic operand to the DEMAND TRIGGER setting to program the input for the new
demand interval pulses.
5
If no trigger is assigned in the DEMAND TRIGGER setting and the CRNT DEMAND METHOD is "Block Interval," use
calculation method 2. If a trigger is assigned, the maximum allowed time between two trigger signals is 60 minutes.
If no trigger signal appears within 60 minutes, demand calculations are performed and available, and the algorithm
resets and starts the new cycle of calculations. The minimum required time for trigger contact closure is 20 µs.
5.3.11.4 Calculation method 3: Rolling demand
This method calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over
the programmed demand time interval, in the same way as Block Interval. The value is updated every minute and
indicates the demand over the time interval just preceding the time of update.

When enabled, the LED test can be initiated from any digital input or user-programmable condition, such as a userprogrammable pushbutton. The control operand is configured under the LED TEST CONTROL setting. The test covers all
LEDs, including the LEDs of the optional user-programmable pushbuttons.
For the enhanced and basic front panels, the test consists of the following three stages:
1.
All 62 LEDs on the relay are illuminated. This is a quick test to verify if any of the LEDs is “burned.” This stage lasts as
long as the control input is on, up to a maximum of one minute. After one minute, the test ends.
2.
All the LEDs are turned off, and then one LED at a time turns on for one second, then back off. The test routine starts at
the top left panel, moving from the top to bottom of each LED column. This test checks for hardware failures that lead
to more than one LED being turned on from a single logic point. This stage can be interrupted at any time.
3.
All the LEDs are turned on. One LED at a time turns off for one second, then back on. The test routine starts at the top
left panel moving from top to bottom of each column of the LEDs. This test checks for hardware failures that lead to
more than one LED being turned off from a single logic point. This stage can be interrupted at any time.
For the graphical front panel, the test consists of the following stages:
1.
All 22 LEDs on the relay are illuminated. This is a quick test to verify if any of the LEDs is "burned." This stage lasts as
long as the control input is on, up to a maximum of one minute. After one minute, the test ends.
2.
All the LEDs are turned off, and then one LED at a time turns on with the orange color for one second, then back off.
The test routine starts at the top left panel, moving from the top to bottom for all 14 LEDs. Then the eight pushbutton
LEDs are tested in the same manner. This test checks for hardware failures that lead to more than one LED being
turned on from a single logic point. This stage can be interrupted at any time.
3.
All the LEDs are turned on with the orange color. One LED at a time turns off for one second, then back on. The test
routine starts at the top left panel moving from top to bottom for all 14 LEDs. Then the eight pushbutton LEDs are
tested in the same manner. This test checks for hardware failures that lead to more than one LED being turned off
from a single logic point. This stage can be interrupted at any time.

Additionally, stages 2 and 3 are repeated twice for the five device status LEDs and nine event cause LEDs, one time
with green color on and the other with red color on.

PRODUCT SETUP
CHAPTER 5: SETTINGS
When testing is in progress, the LEDs are controlled by the test sequence, rather than the protection, control, and
monitoring features. However, the LED control mechanism accepts all the changes to LED states generated by the relay
and stores the actual LED states (on or off) in memory. When the test completes, the LEDs reflect the actual state resulting
from relay response during testing. The reset pushbutton does not clear any targets when the LED Test is in progress.
A dedicated FlexLogic operand, LED TEST IN PROGRESS, is set for the duration of the test. When the test sequence is initiated,
the LED TEST INITIATED event is stored in the event recorder.
The entire test procedure is user-controlled. In particular, stage 1 can last as long as necessary, and stages 2 and 3 can be
interrupted. The test responds to the position and rising edges of the control input defined by the LED TEST CONTROL
setting. The control pulses must last at least 250 ms to take effect. The following diagram explains how the test is
executed.

For the enhanced and basic front panels, there are 48 amber LEDs across the relay LED panels. Each of these indicators
can be programmed to illuminate when the selected FlexLogic operand is in the logic 1 state.
For the basic front panel, the LEDs are located as follows:
•
LED Panel 2 — User-programmable LEDs 1 through 24
•
LED Panel 3 — User programmable LEDs 25 through 48
For the enhanced front panel, the LEDs are located as follows:
•
LED column 2 — User-programmable LEDs 1 through 12
•
LED column 3 — User-programmable LEDs 13 through 24
•
LED column 4 — User-programmable LEDs 25 through 36
•
LED column 5 — User-programmable LEDs 37 through 48
See the LED Indicators section in chapter 4 for information on the location of these indexed LEDs.
The user-programmable LED settings select the FlexLogic operands that control the LEDs. If the LED 1 TYPE setting is “SelfReset” (the default setting), the LED illumination tracks the state of the selected LED operand. If the LED 1 TYPE setting is
“Latched,” the LED, once lit, remains so until reset by the front panel RESET button, from a remote device via a
communications channel, or from any programmed operand, even if the LED operand state de-asserts.

All major self-test alarms are reported automatically with their corresponding FlexLogic operands, events, and targets.
This settings menu allows enabling and disabling of most minor self-test alarms.
When in the Disabled mode, minor alarms do not assert a FlexLogic operand, write to the event recorder, or display target

Control pushbuttons are not typically used for critical operations and are not protected by the control password. However,
by supervising their output operands, the user can dynamically enable or disable control pushbuttons for security reasons.
Each control pushbutton asserts its own FlexLogic operand. Each operand need to be configured appropriately to perform
the required function. Each operand remains asserted as long as the pushbutton is pressed and resets when the
pushbutton is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton manipulation is recognized
by various features that can use control pushbuttons as inputs.
An event is logged in the event record (as per user setting) when a control pushbutton is pressed. No event is logged when
the pushbutton is released. The front panel keys (including control keys) cannot be operated simultaneously—a given key
must be released before the next one can be pressed.

CHAPTER 5: SETTINGS
PRODUCT SETUP
Each pushbutton asserts its own “On” and “Off” FlexLogic operands (for example, PUSHBUTTON 1 ON and PUSHBUTTON 1 OFF).
These operands are available for each pushbutton and are used to program specific actions. If any pushbutton is active,
the ANY PB ON operand is asserted.
Each pushbutton has an associated LED indicator. By default, this indicator displays the present status of the
corresponding pushbutton (on or off). However, each LED indicator can be assigned to any FlexLogic operand through the
PUSHBTN 1 LED CTL setting.
The activation and deactivation of user-programmable pushbuttons depends on whether latched or self-reset mode is
programmed.
•
Latched mode — In latched mode, a pushbutton can be set (activated) by asserting the operand assigned to the
PUSHBTN 1 SET setting, by directly pressing the associated front panel pushbutton, or with the graphical front panel
interface. The state of each pushbutton is stored in non-volatile memory and maintained through a loss of control
power.
The pushbutton is reset (deactivated) in latched mode by asserting the operand assigned to the PUSHBTN 1 RESET
setting, by directly pressing the active front panel pushbutton, or with the graphical front panel interface.
It can also be programmed to reset automatically through the PUSHBTN 1 AUTORST and PUSHBTN 1 AUTORST DELAY
settings. These settings enable the autoreset timer and specify the associated time delay. The autoreset timer can be
used in select-before-operate (SBO) breaker control applications, where the command type (close/open) or breaker
location (feeder number) must be selected prior to command execution. The selection must reset automatically if
control is not executed within a specified time period.
•
Self-reset mode — In self-reset mode, a user-programmable pushbutton can be set (activated) by asserting the
operand assigned to the PUSHBTN 1 SET setting, by pressing the front panel pushbutton, or by the graphical front panel
interface. A pushbutton remains active for the time it is pressed physically or pressed in the graphical front panel
interface, plus the dropout time specified in the PUSHBTN 1 DROP-OUT TIME setting. If the pushbutton is activated via
FlexLogic, the pulse duration is specified by the PUSHBTN 1 DROP-OUT TIME only. The time the operand assigned to the
PUSHBTN 1 SET setting remains On has no effect on the pulse duration.
The pulse duration of the remote set or local front panel pushbutton must be at least 56 ms for a 60 Hz system or
60 ms for a 50 Hz system to operate the pushbutton. This allows the user-programmable pushbuttons to properly
operate during power cycling events and various system disturbances that can cause transient assertion of the
operating signals.
The local and remote operation of each user-programmable pushbutton can be inhibited through the PUSHBTN 1 LOCAL
and PUSHBTN 1 REMOTE settings. If local inhibit is applied, the pushbutton ignores set and reset commands executed
through the front panel pushbuttons. If remote inhibit is applied, the pushbutton ignores set and reset commands
executed through FlexLogic operands.
The inhibit functions are not applied to the autoreset feature. The inhibit function can be used in SBO control operations to
prevent user-programmable pushbutton activation and ensuring “one-at-a-time” select operation.
The inhibit functions can also be used to prevent pushbutton activation from the accidental pressing of the front panel
pushbuttons. The separate inhibit of the local and remote operation simplifies the implementation of local/remote control
supervision.
Pushbutton states can be logged by the event recorder. User-defined messages can also be associated with each
pushbutton and displayed on basic and enhanced front panels when the user-programmable pushbutton is activated, and
when in the latched mode when the user-programmable pushbutton is deactivated. With the graphical front panel
interface, instead of messages, the status of user-programmable pushbuttons can display on a single-line diagram and
can also display in annunciator page windows and in actual values page cells.
For the graphical front panel, the pushbuttons 1 to 8 are linked to the eight physical pushbuttons, and pushbuttons 9 to 16
are mapped to the graphical interface pushbuttons. To set the buttons for pushbuttons 9 to 16, access Settings > Product
Setup > Graphical Panel > Single Line Diagram Editor, click the PB symbol in the toolbox, then configure pushbuttons 9 to
16.
PUSHBUTTON 1 FUNCTION — This setting selects the mode of the pushbutton (Self-Reset, Latched, Disabled). If set to
“Disabled,” the pushbutton is not active and the corresponding FlexLogic operands (both “On” and “Off”) are de-asserted. If
set to "Latched," the pushbutton remains on until reset.

CHAPTER 5: SETTINGS
PUSHBTN 1 ID TEXT — This setting specifies the top 20-character line of the user-programmable pushbutton message and is
intended to provide ID information of the pushbutton. For example, the text displays in the Event Record. See the Userdefinable Displays section in this chapter for instructions on how to enter alphanumeric characters from the keypad. On a
graphical front panel, this setting instead controls the label of the user-programmable pushbutton component on singleline diagrams.
PUSHBTN 1 ON TEXT — This setting specifies the bottom 20-character line of the user-programmable pushbutton message
and is displayed when the pushbutton is in the “on” position. See the User-definable Displays section for instructions on
entering alphanumeric characters from the keypad. On a graphical front panel, this setting instead controls the on status
text of the user-programmable pushbutton component on single-line diagrams. This setting is not applied to the physical
pushbuttons on the graphical front panel.
PUSHBTN 1 OFF TEXT — This setting specifies the bottom 20-character line of the user-programmable pushbutton message
and displays when the pushbutton is deactivated and the PUSHBUTTON 1 FUNCTION is “Latched.” A message does not
display when the PUSHBUTTON 1 FUNCTION is “Self-reset” as the pushbutton operand status is implied to be “Off” upon its
release. The length of the “Off” message is configured with the PRODUCT SETUP  DISPLAY PROPERTIES  FLASH MESSAGE
TIME setting. On a graphical front panel, this setting instead controls the off status text of the user-programmable
pushbutton component on single-line diagrams. This setting is not applied to the physical pushbuttons on the graphical
front panel.
PUSHBTN 1 HOLD — This setting specifies the time required for a front panel pushbutton to be pressed before it is deemed
active. This timer is reset upon release of the pushbutton. Note that user-programmable pushbutton operation requires the
front panel pushbutton to be pressed a minimum of 56 ms for a 60 Hz system or 60 ms for a 50 Hz system. This minimum
time is required prior to activating the user-programmable pushbutton hold timer.
PUSHBTN 1 SET — This setting assigns the FlexLogic operand serving to activate the user-programmable pushbutton
element. The duration of the incoming set signal must be at least 56 ms for a 60 Hz system or 60 ms for a 50 Hz system.
5
PUSHBTN 1 RESET — This setting assigns the FlexLogic operand serving to deactivate the user-programmable pushbutton
element. This setting is applicable only if the user-programmable pushbutton is in "Latched" mode.
PUSHBTN 1 AUTORST — This setting enables the user-programmable pushbutton autoreset feature. This setting is applicable
only if the pushbutton is in “Latched” mode.
PUSHBTN 1 AUTORST DELAY — This setting specifies the time delay for automatic reset of the pushbutton when in "Latched"
mode.
PUSHBTN 1 REMOTE — This setting assigns the FlexLogic operand serving to inhibit user-programmable pushbutton
operation from the operand assigned to the PUSHBTN 1 SET or PUSHBTN 1 RESET settings.
PUSHBTN 1 LOCAL — This setting assigns the FlexLogic operand serving to inhibit user-programmable pushbutton operation
from the front panel pushbuttons. This inhibit functionality is not applicable to pushbutton autoreset.
PUSHBTN 1 DROP-OUT TIME — This setting applies only to “Self-Reset” mode and specifies the duration of the userprogrammable pushbutton active status after the front panel pushbutton or graphical front panel interface pushbutton
has been released. When activated remotely, this setting specifies the entire activation time of the pushbutton; the length
of time the operand selected by PUSHBTN 1 SET remains on has no effect on the pulse duration.
PUSHBTN 1 LED CTL — This setting assigns the FlexLogic operand serving to drive the front panel pushbutton LED. If this
setting is “Off,” then LED operation is directly linked to the PUSHBUTTON 1 ON operand. This setting is not applied to
Pushbuttons 9 to 16 on the graphical front panel, where the label background shows the orange glow color for the "on"
state.
PUSHBTN 1 MESSAGE — This setting controls the behavior of the user-programmable pushbutton on message that is
programmed in the PUSHBTN 1 ID and PUSHBTN 1 ON TEXT settings, and the behavior of the user-programmable pushbutton
off message that is programmed in the PUSHBTN 1 ID and PUSHBTN 1 OFF TEXT settings. This settings has no effect on the
graphical front panel.
When set to "Disabled", user-programmable pushbutton messages do not display. Otherwise the on message displays
when the user-programmable pushbutton becomes activated, and if in the "Latched" mode the off message displays
when the user-programmable pushbutton becomes deactivated.
When set to "Normal", the duration the message displays is as specified by the FLASH MESSAGE TIME setting.

When set to "High Priority", the duration of the off message is as specified by the FLASH MESSAGE TIME setting, but the on
message is displayed as long as the user-programmable pushbutton is activated. While activated, target and other
messages are suppressed. To allow front panel keypad operation, when a keypad button is pressed the message is
supressed for 10 seconds.
PUSHBUTTON 1 EVENTS — If this setting is enabled, each user-programmable pushbutton state change is logged as an event

facilitate text entry and Modbus register data pointer options for defining the user display content.
This feature is not supported with the optional graphical front panel.
Once programmed, the user-definable displays can be viewed in two ways.
•
Keypad — Use the MENU key to select the USER DISPLAY menu item to access the first user-definable display (note that
only the programmed screens are displayed). The screens can be scrolled using the up and down arrow keys. The
display disappears after the default message time-out period specified by the PRODUCT SETUP  DISPLAY PROPERTIES

•
User-programmable control input — The user-definable displays also respond to the INVOKE AND SCROLL setting. Any
FlexLogic operand (in particular, the user-programmable pushbutton operands), can be used to navigate the
programmed displays.
On the rising edge of the configured operand (such as when the pushbutton is pressed), the displays are invoked by
showing the last user-definable display shown during the previous activity. From this moment onward, the operand
acts exactly as the down key and allows scrolling through the configured displays. The last display wraps up to the
first one. The INVOKE AND SCROLL input and the down arrow key operate concurrently.
When the default timer expires (set by the DEFAULT MESSAGE TIMEOUT setting), the relay starts to cycle through the user
displays. The next activity of the INVOKE AND SCROLL input stops the cycling at the currently displayed user display, not
at the first user-defined display. The INVOKE AND SCROLL pulses must last for at least 250 ms to take effect.

CHAPTER 5: SETTINGS
This menu is used to enter user-defined text and user-selected Modbus-registered data fields into the particular user
display. Each user display consists of two 20-character lines (top and bottom). The tilde (~) character is used to mark the
start of a data field – the length of the data field needs to be accounted for. Up to five separate data fields can be entered
in a user display – the nth tilde (~) refers to the nth item.
A user display can be entered from the front panel keypad or the EnerVista interface (preferred for convenience). The
following procedure shows how to enter text characters in the top and bottom lines from the front panel keypad:
1.
Select the line to be edited.
2.

This option is available when an Inter-Relay Communications card is specified at the time of ordering (see the
Order Code tables). With the option, direct inputs/outputs display by default. When you enable the
teleprotection feature, direct I/O is not visible.
Direct inputs and outputs exchange status information (inputs and outputs) between UR-series relays connected directly
via type 7 digital communications cards. The mechanism is very similar to IEC 61850 GOOSE, except that communications
takes place over a non-switchable isolated network and is optimized for speed. On type 7 cards that support two channels,
direct output messages are sent from both channels simultaneously. This effectively sends direct output messages both
ways around a ring configuration. On type 7 cards that support one channel, direct output messages are sent only in one
direction. Messages are resent (forwarded) when it is determined that the message did not originate at the receiver.
Direct Inputs and Outputs are initiated automatically and start running once at least one Direct Output in the given UR is
set to anything but Off.
For the direct I/Os to function properly, all UR devices sending I/Os using an Inter-Relay Communications card must have
identical firmware revisions.
Teleprotection inputs/outputs and direct inputs/outputs are mutually exclusive. As such, they cannot be used
simultaneously. Once teleprotection inputs and outputs are enabled, direct inputs and outputs are disabled, and
vice versa.
Direct output message timing is similar to GOOSE message timing. Integrity messages (with no state changes) are sent at
least every 1000 ms. Messages with state changes are sent within the main pass scanning the inputs and asserting the
outputs unless the communication channel bandwidth has been exceeded. Two self-tests are performed and signaled by
the following FlexLogic operands:
•
DIRECT RING BREAK (direct input/output ring break). This FlexLogic operand indicates that direct output messages sent
from a UR-series relay are not being received back by the relay.
•
DIRECT DEVICE 1 OFF to DIRECT DEVICE 16 OFF (direct device offline). These FlexLogic operands indicate that direct output
messages from at least one direct device are not being received.
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
5-135
PRODUCT SETUP
CHAPTER 5: SETTINGS
Direct input and output settings are similar to remote input and output settings. The equivalent of the remote device name
strings for direct inputs and outputs is the DIRECT OUTPUT DEVICE ID setting, which identifies the relay in all direct output
messages. All UR-series IEDs in a ring need to have unique numbers assigned. The IED ID is used to identify the sender of
the direct input and output message.
If the direct input and output scheme is configured to operate in a ring (DIRECT I/O CH1 RING CONFIGURATION or DIRECT I/O
CH2 RING CONFIGURATION is “Yes”), all direct output messages are received back. If not, the direct input/output ring break
self-test is triggered. The self-test error is signaled by the DIRECT RING BREAK FlexLogic operand.
Select the DIRECT I/O DATA RATE to match the data capabilities of the communications channel. All IEDs communicating
over direct inputs and outputs must be set to the same data rate. UR-series IEDs equipped with dual-channel
communications cards apply the same data rate to both channels. Delivery time for direct input and output messages is
approximately 0.2 of a power system cycle at 128 kbps and 0.4 of a power system cycle at 64 kbps, per each "bridge."

The G.703 modules are fixed at 64 kbps. The DIRECT I/O DATA RATE setting is not applicable to these modules.
The DIRECT I/O CHANNEL CROSSOVER setting applies to a G60 with dual-channel communication cards and allows crossing
over messages from channel 1 to channel 2. This places all UR-series IEDs into one direct input and output network
regardless of the physical media of the two communication channels.
The following application examples illustrate the basic concepts for direct input and output configuration. See the Inputs
and Outputs section in this chapter for information on configuring FlexLogic operands (flags, bits) to be exchanged.
Example 1: Extending the input/output capabilities of a UR-series relay
Consider an application that requires additional quantities of contact inputs or output contacts or lines of programmable
logic that exceed the capabilities of a single UR-series chassis. The problem is solved by adding an extra UR-series IED,
such as the C30, to satisfy the additional input and output and programmable logic requirements. The two IEDs are
connected via single-channel digital communication cards as shown in the figure.

For UR-series IED 2:

The message delivery time is about 0.2 of power cycle in both ways (at 128 kbps); that is, from device 1 to device 2, and
from device 2 to device 1. Different communications cards can be selected by the user for this back-to-back connection
(for example: fiber, G.703, or RS422).
Example 2: Interlocking busbar protection
A simple interlocking busbar protection scheme could be accomplished by sending a blocking signal from downstream
devices, say 2, 3, and 4, to the upstream device that monitors a single incomer of the busbar, as shown.

Message delivery time is approximately 0.2 of power system cycle (at 128 kbps) times number of ‘bridges’ between the
origin and destination. Dual-ring configuration effectively reduces the maximum ‘communications distance’ by a factor of
two.
In this configuration the following delivery times are expected (at 128 kbps) if both rings are healthy:
IED 1 to IED 2: 0.2 of power system cycle
IED 1 to IED 3: 0.4 of power system cycle
IED 1 to IED 4: 0.2 of power system cycle
IED 2 to IED 3: 0.2 of power system cycle
IED 2 to IED 4: 0.4 of power system cycle
IED 3 to IED 4: 0.2 of power system cycle
If one ring is broken (say TX2-RX2) the delivery times are as follows:
IED 1 to IED 2: 0.2 of power system cycle
IED 1 to IED 3: 0.4 of power system cycle
IED 1 to IED 4: 0.6 of power system cycle
IED 2 to IED 3: 0.2 of power system cycle
IED 2 to IED 4: 0.4 of power system cycle
IED 3 to IED 4: 0.2 of power system cycle
A coordinating timer for this bus protection scheme could be selected to cover the worst case scenario (0.4 of a power
system cycle). Upon detecting a broken ring, the coordination time is adaptively increased to 0.6 of a power system cycle.
The complete application requires addressing a number of issues, such as failure of both the communications rings, failure
or out-of-service conditions of one of the relays, and so on. Self-monitoring flags of the direct inputs and outputs feature
primarily are used to address these concerns.

IED 1 to IED 3: 0.5 of power system cycle
IED 2 to IED 3: 0.2 of power system cycle
In this scheme, IEDs 1 and 3 do not communicate directly. IED 2 must be configured to forward the messages as explained
in the Inputs and Outputs section. Implement a blocking pilot-aided scheme with more security and, ideally, faster
message delivery time. This is accomplished using a dual-ring configuration as shown here.

adds up messages that failed the CRC check. When the failed CRC counter reaches the user-defined level specified by the

•
Message count and length of the monitoring window — To monitor communications integrity, the relay sends 1
message per second (at 64 kbps) or 2 messages per second (at 128 kbps) even if there is no change in the direct
outputs. For example, setting the CRC ALARM CH1 MESSAGE COUNT to “10000,” corresponds a time window of about 160
minutes at 64 kbps and 80 minutes at 128 kbps. If the messages are sent faster as a result of direct outputs activity,
the monitoring time interval shortens. Take this into account when determining the CRC ALARM CH1 MESSAGE COUNT
setting. For example, if the requirement is a maximum monitoring time interval of 10 minutes at 64 kbps, then the CRC
ALARM CH1 MESSAGE COUNT is set to 10  60  1 = 600.
•
Correlation of failed CRC and bit error rate (BER) — The CRC check can fail if one or more bits in a packet are
corrupted. Therefore, an exact correlation between the CRC fail rate and the BER is not possible. Under certain
assumptions an approximation can be made as follows. A direct input and output packet containing 20 bytes results
in 160 bits of data being sent and therefore, a transmission of 63 packets is equivalent to 10,000 bits. A BER of 10–4
implies 1 bit error for every 10000 bits sent or received. Assuming the best case of only 1 bit error in a failed packet,
having 1 failed packet for every 63 received is about equal to a BER of 10–4.

This option is available when an Inter-Relay Communications card is specified at the time of ordering (see the
Order Code tables). With the option, direct inputs/outputs display by default. When you enable the
teleprotection feature, direct I/O is not visible.
Digital teleprotection transfers protection commands between two or three relays in a secure, fast, dependable, and
deterministic way. Possible applications are permissive or blocking pilot schemes and direct transfer trip (DTT).
Teleprotection can be applied over any analog or digital channels and any communications media, such as direct fiber,
copper wires, optical networks, or microwave radio links. A mixture of communication media is possible.
Once teleprotection is enabled and the teleprotection input/outputs are configured, data packets are transmitted
continuously every 1/4 cycle (3/8 cycle if using C37.94 modules) from peer-to-peer. Security of communication channel
data is achieved by using CRC-32 on the data packet.

Teleprotection inputs/outputs and direct inputs/outputs are mutually exclusive. As such, they cannot be used
simultaneously. Once teleprotection inputs and outputs are enabled, direct inputs and outputs are blocked, and
vice versa.
NUMBER OF TERMINALS — Specifies whether the teleprotection system operates between two peers or three peers.
NUMBER OF CHANNELS — Specifies how many channels are used. If the NUMBER OF TERMINALS is “3” (three-terminal system),

LOCAL RELAY ID NUMBER, TERMINAL 1 RELAY ID NUMBER, and TERMINAL 2 RELAY ID NUMBER — In installations that use
multiplexers or modems, it is desirable to ensure that the data used by the relays protecting a given line is from the correct
relays. The teleprotection function performs this check by reading the message ID sent by transmitting relays and
comparing it to the programmed ID in the receiving relay. This check is also used to block inputs if inadvertently set to
loopback mode or data is being received from a wrong relay by checking the ID on a received channel. If an incorrect ID is
found on a channel during normal operation, the TELEPROT CH1 ID FAIL or TELEPROT CH2 ID FAIL FlexLogic operand is set, driving the
event with the same name and blocking the teleprotection inputs. For commissioning purposes, the result of channel
identification is also shown in the STATUS  CHANNEL TESTS  VALIDITY OF CHANNEL CONFIGURATION actual value. The
default value of “0” for the LOCAL RELAY ID NUMBER indicates that relay ID is not to be checked. On two- terminals twochannel systems, the same LOCAL RELAY ID NUMBER is transmitted over both channels; as such, only the TERMINAL 1 ID

REMOTE RESOURCES
5.4 Remote resources
5.4.1 Remote resources configuration
When the G60 is ordered with a process card module as a part of HardFiber system, an additional Remote Resources
menu tree is available in the EnerVista software to allow configuration of the HardFiber system.
Figure 5-66: Remote Resources configuration menu
5
The remote resources settings configure a G60 with a process bus module to work with HardFiber Bricks. Remote
resources configuration is only available through the EnerVista software, and is not available through the G60 front panel.
A Brick provides eight AC measurements, along with contact inputs, DC analog inputs, and contact outputs, to be the
remote interface to field equipment such as circuit breakers and transformers. The G60 with a process bus module has
access to all of the capabilities of up to eight Bricks. Remote resources settings configure the point-to-point connection
between specific fiber optic ports on the G60 process card and specific Brick. The relay is then configured to measure
specific currents, voltages and contact inputs from those Bricks, and to control specific outputs.
The configuration process for remote resources is straightforward and consists of the following steps.
•
Configure the field units. This establishes the point-to-point connection between a specific port on the relay process
bus module, and a specific digital core on a specific Brick. This is a necessary first step in configuring a process bus
relay.
•
Configure the AC banks. This sets the primary and secondary quantities and connections for currents and voltages. AC
bank configuration also provides a provision for redundant measurements for currents and voltages, a powerful
reliability improvement possible with process bus.
•
Configure signal sources. This functionality of the G60 has not changed other than the requirement to use currents
and voltages established by AC bank configuration under the remote resources menu.
•
Configure field contact inputs, field contact outputs, RTDs, and transducers as required for the application's
functionality. These inputs and outputs are the physical interface to circuit breakers, transformers, and other
equipment. They replace the traditional contact inputs and outputs located at the relay to virtually eliminate copper
wiring.
•
Configure shared inputs and outputs as required for the application's functionality. Shared inputs and outputs are
distinct binary channels that provide high-speed protection quality signaling between relays through a Brick.
For additional information on how to configure a relay with a process bus module, see the HardFiber Process Bus System
Instruction Manual.

5
See the Introduction to AC Sources section at the beginning of this chapter for details.
These settings are critical for all features that have settings dependent on current measurements. When the relay is
ordered, the CT module must be specified to include a standard or sensitive ground input. As the phase CTs are connected
in wye (star), the calculated phasor sum of the three phase currents (IA + IB + IC = neutral current = 3I0) is used as the input
for the neutral overcurrent elements. In addition, a zero-sequence (core balance) CT which senses current in all of the
circuit primary conductors, or a CT in a neutral grounding conductor can also be used. For this configuration, the ground
CT primary rating must be entered. To detect low level ground fault currents, the sensitive ground input can be used. In this
case, the sensitive ground CT primary rating must be entered. See chapter 3 for more details on CT connections.
Enter the rated CT primary current values. For both 1000:5 and 1000:1 CTs, the entry would be 1000. For correct operation,
the CT secondary rating must match the setting (which must also correspond to the specific CT connections used).
The following example illustrates how multiple CT inputs (current banks) are summed as one source current. Given the
following current banks:
•
F1: CT bank with 500:1 ratio
•
F5: CT bank with 1000:1 ratio
•
M1: CT bank with 800:1 ratio
The following rule applies:
SRC 1 = F1 + F5 + M1
Eq. 5-7
1 pu is the highest primary current. In this case, 1000 is entered and the secondary current from the 500:1 and 800:1 ratio
CTs are adjusted to that created by a 1000:1 CT before summation. If a protection element is set up to act on SRC 1
currents, then a pickup level of 1 pu operates on 1000 A primary.
The same rule applies for current sums from CTs with different secondary taps (5 A and 1 A).

With VTs installed, the relay can perform voltage measurements as well as power calculations. Enter the PHASE VT F5
CONNECTION made to the system as “Wye” or “Delta.” An open-delta source VT connection is entered as “Delta.”
The nominal PHASE VT F5 SECONDARY voltage setting is the voltage across the relay input terminals when nominal
voltage is applied to the VT primary.
For example, on a system with a 13.8 kV nominal primary voltage and with a 14400:120 volt VT in a delta
connection, the secondary voltage is 115; that is, (13800 / 14400) × 120. For a wye connection, the voltage value
entered must be the phase to neutral voltage, which is 115 
= 66.4.
On a 14.4 kV system with a delta connection and a VT primary to secondary turns ratio of 14400:120, the voltage

safe period of time while waiting for the signals to reappear or for the distortions to decay. After changing this setting,
restart the relay using Maintenance > Reboot Relay Command.

SYSTEM SETUP
CHAPTER 5: SETTINGS
The phase sequence of the power system is required to properly calculate sequence components and power parameters.
The PHASE ROTATION setting matches the power system phase sequence and informs the relay of the actual system phase
sequence, either ABC or ACB. CT and VT inputs on the relay, labeled as A, B, and C, must be connected to system phases A,
B, and C for correct operation.
The REVERSE PH ROTATION setting allows the user to dynamically change the phase rotation used for phasor calculations.
This allows the G60 to follow the current phase rotation of the protected generator. For example, if the PHASE ROTATION
setting is “ABC” but the condition defined for opposite phase rotation is true, then the phase rotation used for phasor
calculation switches to “ACB.” This feature is only intended for use in special applications, such as pumped storage
schemes.
Typical application of using Reverse Phase Rotation is the pumped-storage hydroelectricity application. Water is pumped
from a lower elevation reservoir to a higher elevation (pumping or motor mode) during the off-peak period when low-cost
surplus electricity is available, and during periods of high electrical demand, the stored water is released through turbines
to produce electricity (generator mode), where pump operation is realized through phase rotation reversal operation
because the hydraulic units are designed to operate as turbines when rotating in one direction and as pumps when
rotating in the opposite direction.
When the operand assigned to the REVERSE PH ROTATION setting is logical "0," the phase rotation is matching the one
defined by the PHASE ROTATION setting, ABC for example. When this operand is logical "1," the phase rotation changes to
the opposite, ACB for the same example. Note that after successful rotation switching, the next switching is allowed only
after nine power cycles.
Typically, different relay setting groups are used to protect pumping operation mode and generating operation mode of
the hydraulic units respectively, therefore the logic for switching setting groups can be directly used to control the REVERSE
PH ROTATION.
Every time rotation change is performed, protection is blocked for three power cycles.
5
The FREQUENCY AND PHASE REFERENCE setting determines which signal source is used (and hence which AC signal) for
phase angle reference. The AC signal used is prioritized based on the AC inputs configured for the signal source. Phase
voltages takes precedence, followed by auxiliary voltage, then phase currents, and finally ground current.
For three phase selection, phase A is used for angle referencing (VANGLE REF = VA), while Clarke transformation of the phase
signals is used for frequency metering and tracking (VFREQUENCY = (2VA - VB - VC) / 3) for better performance during fault,
open pole, and VT and CT fail conditions.
The phase reference and frequency tracking AC signals are selected based upon the source configuration, regardless of
whether or not a particular signal is actually applied to the relay.
Phase angle of the reference signal always displays zero degrees and all other phase angles are relative to this signal. If
the pre-selected reference signal is not measurable at a given time, the phase angles are not referenced.
The phase angle referencing is done via a phase locked loop, which can synchronize independent UR-series relays if they
have the same AC signal reference. This results in very precise correlation of phase angle indications between different URseries relays.
FREQUENCY TRACKING is set to “Disabled” only in unusual circumstances; consult GE Grid Solutions for special variable-
frequency applications.
The frequency tracking feature functions only when the G60 is in the “Programmed” mode. If the G60 is “Not
Programmed,” then metering values are available but can exhibit significant errors.

“5” in a particular CT/VT module. See the Introduction to AC Sources section at the beginning of this chapter for details.
It is possible to select the sum of all CT combinations. The first channel displayed is the CT to which all others are referred.
For example, the selection “F1+F5” indicates the sum of each phase from channels “F1” and “F5,” scaled to whichever CT
has the higher ratio. Selecting “None” hides the associated actual values.
The approach used to configure the AC sources consists of several steps; first step is to specify the information about each
CT and VT input. For CT inputs, this is the nominal primary and secondary current. For VTs, this is the connection type, ratio
and nominal secondary voltage. Once the inputs have been specified, the configuration for each source is entered,
including specifying which CTs are summed together.
5.5.3.1 User selection of AC parameters for comparator elements
CT/VT modules automatically calculate all current and voltage parameters from the available inputs. Users must select the
specific input parameters to be measured by every element in the relevant settings menu. The internal design of the
element specifies which type of parameter to use and provides a setting for source selection. In elements where the
parameter can be either fundamental or RMS magnitude, such as phase time overcurrent, two settings are provided. One
setting specifies the source, the second setting selects between fundamental phasor and RMS.
5.5.3.2 AC input actual values
The calculated parameters associated with the configured voltage and current inputs are displayed in the current and

5.5.3.3 Disturbance detectors (internal)
The disturbance detector (ANSI 50DD) element is a sensitive current disturbance detector that detects any disturbance on
the protected system. The 50DD function is used directly in some elements in the relay, for example VT Fuse Failure
detector or Fault Report. It can also be used to supervise current-based elements to prevent maloperation as a result of
the wrong settings or external CT wiring problem. A disturbance detector is provided for each source.
The 50DD function responds to the changes in magnitude of the sequence currents. The disturbance detector logic is as
follows.

The disturbance detector responds to the change in currents of twice the current cut-off level. The default cut-off threshold

(PRODUCT SETUP  DISPLAY PROPERTIES  CURRENT CUT-OFF LEVEL) controls the sensitivity of the disturbance detector

There are two breaker control elements for each CT/VT module installed. The following settings are available for each
breaker control element.
BREAKER 1 FUNCTION — This setting enables and disables the operation of the breaker 1 control feature.
BREAKER1 PUSH BUTTON CONTROL — Set to “Enable” to allow front panel pushbutton open/close control operations.
BREAKER1 TAGGING — Set to "Enable" to allow the graphical front panel to tag breaker 1. When tagged, the following
operations are disabled: pushbutton open/close, IEC 61850 open/close, and close command initiated by BREAKER 1 CLOSE
setting. The trip command issued by the Trip Out element or BREAKER 1 OPEN setting is not affected.
BREAKER1 SUBSTITUTN — Set to "Enable" to allow the graphical front panel to substitute breaker 1 status. When substituted,
breaker 1 control open/close status is forced to the substituted value.
BREAKER1 BYPASS — Set to "Enable" to allow the graphical front panel to bypass breaker 1 interlocking. When asserted,
BREAKER 1 BLK OPEN and BREAKER 1 BLK CLOSE settings are bypassed.
BREAKER 1 NAME — Assign a user-defined name (up to six characters) to the breaker. This name is used in flash messages
related to breaker 1.
BREAKER 1 MODE — Selects “3-Pole” mode, where all breaker poles are operated simultaneously, or “1-Pole” mode where all
breaker poles are operated either independently or simultaneously.
BREAKER 1 OPEN — Selects an operand that when activated, and unless blocked, initiates the Breaker 1 open and individual
phase trip commands.
BREAKER 1 BLK OPEN — Selects an operand that prevents initiation of Breaker 1 open and individual phase trip commands.
This setting can be used for blocking circuit breaker tripping for instance when breaker monitoring detects conditions such
as low SF6 gas density during which breaker opening can cause damage.
BREAKER 1 CLOSE — Selects an operand that when activated, and unless blocked, initiates the Breaker 1 close commands.
BREAKER 1 BLK CLOSE — Selects an operand that prevents initiation of Breaker 1 close commands. This setting can be used
for blocking circuit breaker closing, for instance to prevent closing into a closed ground switch.
BREAKER1 A/3P CLSD — Selects an operand, usually a contact input connected to a breaker auxiliary position tracking
mechanism. This input is for a normally-open 52/a status input that creates a logic 1 when the breaker is closed. If the
BREAKER 1 MODE setting is selected as "3-Pole," this setting selects a single 52/a input as the operand used to track the
breaker open or closed position. If the mode is selected as "1-Pole," the input mentioned is used to track phase A and the
BREAKER 1 B and BREAKER 1 C settings select operands to track phases B and C, respectively.
BREAKER1 A/3P OPND — Selects an operand, usually a contact input, that is for a normally-closed 52/b status input that
creates a logic 1 when the breaker is open. If a separate 52/b contact input is not available, then the inverted 52/a status
signal or the inverted BREAKER 1 CLOSED status signal can be used.
BREAKER 1 B CLOSED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as singlepole, this input is used to track the breaker phase B closed position as outlined for phase A.
BREAKER 1 B OPENED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase B opened position as outlined for phase A.
BREAKER 1 C CLOSED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase C closed position as outlined for phase A.
BREAKER 1 C OPENED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase C opened position as outlined for phase A.
BREAKER 1 TOPERATE — This setting specifies the required interval to overcome transient disagreement between the 52/a
and 52/b auxiliary contacts during breaker operation. If transient disagreement still exists after this time has expired, the
BREAKER 1 BAD STATUS FlexLogic operand is asserted for alarm or blocking purposes.
BREAKER 1 EXT ALARM — This setting selects an operand, usually an external contact input connected to a breaker alarm
reporting contact. While the selected operand is active, the BREAKER 1 TROUBLE operand is activated.
BREAKER 1 ALARM DELAY — This setting specifies the delay interval during which a disagreement of status among the threepole position tracking operands does not declare a pole disagreement. This allows for non-simultaneous operation of the
poles.
BREAKER 1 OPEN SEAL-IN — This setting specifies the seal-in time of the three-pole open command initiated by either the
Trip Out element or a manual open command to the circuit breaker.

CHAPTER 5: SETTINGS
MANUAL CLOSE RECAL1 TIME — This setting specifies the seal-in time of the close commands due to an operator-initiated
manual close command to the circuit breaker.
BREAKER 1 OUT OF SV — Selects an operand indicating that breaker 1 is out-of-service.
BREAKER 1 RACKED-IN — This setting selects a contact input to show whether the breaker is racked-in or racked-out. The
racked-in or racked-out status is used to indicate dynamically the status of breaker symbol, only applied in the single-line
diagram in the graphical front panel. If this setting is set to Off, the racked status is not considered.
IEC 61850 functionality is permitted when the G60 device is in "Programmed" mode and not in local control mode.

The breaker element has direct hard-coded connections to the IEC 61850 model as shown in the logic diagram. This allows
remote open/close operation of each breaker, using either CSWI or XCBR IEC 61850 logical nodes. IEC 61850 select-beforeoperate functionality, local/remote switch functionality, along with blocking of open/close commands are provided. Note
that the dwell time for the IEC 61850 trip and close commands shown is one protection pass only. To maintain the close/
open command for a certain time, do so by setting the seal-in timers BREAKER 1 OPEN SEAL-IN and MANUAL CLOSE RECAL1

The disconnect switch control element contains the auxiliary logic for status and serves as the interface for opening and
closing of disconnect switches from SCADA or through the front panel interface. The disconnect switch control element
can be used to create interlocking functionality. For greater security in determination of the switch pole position, both the
89/a and 89/b auxiliary contacts are used with reporting of the discrepancy between them. There are eight disconnect
switch control elements for each CT/VT module installed.
To use this element, configure the contact outputs that open and close the disconnect switch to use FlexLogic operands
SWITCH 1 OFF CMD and SWITCH 1 ON CMD, and configure the disconnect switch control element's inputs as outlined here.
SWITCH 1 FUNCTION — This setting enables and disables operation of the disconnect switch element.
SWITCH 1 NAME — Assign a user-defined name (up to six characters) to the disconnect switch. This name is used in flash
messages related to disconnect switch 1.
SWITCH 1 MODE — This setting selects “3-Pole” mode, where disconnect switch poles have a single common auxiliary
switch, or “1-Pole” mode where each disconnect switch pole has its own auxiliary switch.

The relay using a given FlexCurve applies linear approximation for times between the user-entered points. Take
care when setting the two points that are close to the multiple of pickup of 1; that is, 0.98 pu and 1.03 pu. It is
recommended to set the two times to a similar value, otherwise the linear approximation can result in undesired
behavior for the operating quantity that is close to 1.00 pu.
5.5.6.2 FlexCurve configuration with EnerVista software
The EnerVista software allows for easy configuration and management of FlexCurves and their associated data points.
Prospective FlexCurves can be configured from a selection of standard curves to provide the best approximate fit, then
specific data points can be edited afterwards. Alternately, curve data can be imported from a specified file (.csv format) by
selecting the EnerVista Import Data From setting (Settings > System Setup > FlexCurves > FlexCurve).
Curves and data can be exported, viewed, and cleared by clicking the appropriate buttons. FlexCurves are customized by
editing the operating time (ms) values at pre-defined per-unit current multiples. Note that the pickup multiples start at zero
(implying the "reset time"), operating time below pickup, and operating time above pickup.
5.5.6.3 Recloser curve editing
Recloser curve selection is special in that recloser curves can be shaped into a composite curve with a minimum response
time and a fixed time above a specified pickup multiples. There are 41 recloser curve types supported. These definite
operating times are useful to coordinate operating times, typically at higher currents and where upstream and
downstream protective devices have different operating characteristics. The recloser curve configuration window shown
here appears when the Initialize From setting in the EnerVista software is set to “Recloser Curve” and the Initialize
FlexCurve button is clicked.

5.5.6.4 Example
A composite curve can be created from the GE_111 standard with MRT = 200 ms and HCT initially disabled and then
enabled at eight times pickup with an operating time of 30 ms. At approximately four times pickup, the curve operating
time is equal to the MRT and from then onwards the operating time remains at 200 ms.

The G60 is provided with an optional Phasor Measurement Unit (PMU) feature. This feature is specified as a
software option at the time of ordering. The number of PMUs available also depends on this option. Using the

5.5.7.2 UR synchrophasor implementation
Phasors are used in protection relays. When these phasors are referenced to a common time base, they are referred to as
synchrophasors. A vastly improved method for tracking power system dynamic phenomena for power system monitoring,
protection, operation, and control can be realized when synchrophasors from different locations within the power system
are networked to a central location.
The G60 offers PMU features over two communication standards, IEC 61850-90-5 and IEEE C37.118. The figure shows
complete synchrophasor implementation.

Synchrophasor data as measured and calculated by PMUs is used to assess the condition of the electrical power network.
The IEEE C37.118 standards define synchrophasors and related message formats to transmit synchrophasor data.
Synchrophasor streaming via IEEE C37.118 has proven to work but the need to have a communication mechanism that is
compliant with the concept of IEC 61850 has led to the development of IEC 61850-90-5. The IEC 61850-90-5 technical
report defines the packet structure for multicast routing of streamed Sampled Value (SV) known as R-SV.
UR firmware versions 7.0 and above have a 90-5 based R-SV implementation equivalent in structure and configuration to
that of the existing IEEE C37.118 implementation of firmware version 6.0, that is, synchrophasor data at rates up to 60 Hz
for metering and 120 Hz for protection class synchrophasors. The following two figures depict the general data flow for the
generation of synchrophasor data for IEC 61850-90-5. In the first figure, when IEC 61850-90-5 is selected all real and
virtual sources are available for the IEC 61850-90-5 PMUs.

Precise time input to the relay from the international time standard, via either IRIG-B or PTP, is vital for correct
synchrophasor measurement and reporting. For IRIG-B, a DC level shift IRIG-B receiver must be used for the PMU to
output proper synchrophasor values.
Depending on the applied filter, the synchrophasors that are produced by PMUs are classified as either P (protection) or M
(Measurement) class synchrophasors. Synchrophasors available within the UR that have no filtering applied are classified
as NONE, which within the standard is classified as PRES OR UNKNOWN under the Calculation Method - ClcMth. Each
Logical Device PMU supports one MxxMMXU, MxxMSQI, PxxxMMXU , PxxxMSQI, NxxMMXU, and one NxxMSQI logical node.

IEEE C37.118 Class (P or M) of that PMU. The value of the SmpRate DO in the Report Control Block is set based on the value
of the Sample Rate in the PMU. The Class of the Dataset are mapped into the MSVID of the Dataset (see text that follows for
the overall name of the MSVID). If other PMUs are mapped into the same aggregator with different Sample Rates or from
different classes, then a Self-Test error (DatSetErr) is set and dataset transmission is blocked.
A setting value — MSVID — is created with a maximum input range of 56 characters (=64 less 6 for the IDCode less 2 for the
Class).
The value of MSVID in the dataset is a concatenation of the aggregator IDCode and the MSVID setting value in the format:
MSVID-AggregatorIDCode-CLASS where CLASS is P, M, or N (for None) – depending on the Class of the first PMU included in
the Aggregator.
Synchrophasor Rectangular Format and Integer data types are NOT supported in IEC 61850-90-5 (only supported
with IEEE C37.118) and not to set — GGIO1 that contains 16 digital status indication points — aggregated as a 16 bit
bitstring and 16 analog points. The Analog GGIO values are selectable from any FlexAnalog value in the UR. For
firmware versions 7.0 and later, the description fields for the phasors, analog, and digital channels are populated
with the 16 character name field provided within the Basic Configuration menu. Additionally, the names of the 16
binary points are implemented as numbered descriptions — d1, d2, d3, and so on. The number of descriptions are
equal to the number of bits configured in the 16 bit digital status word.
5
All bitstrings less than or equal to 32 bits in length map into a 32 bit bitstring in an IEC 61850-90-5 dataset.
The Value of the Nominal Frequency of the chassis is instantiated as a DO in LPHD of LD1. The value is named
HzNom and is an Integer Status (INS).
The UR also supports the option to apply no filtering to the synchrophasors. If no filtering is applied (PMU Class = None),
according to the standard, the ClcMth attribute is PRES. The semantic of the ClcMth used is not carried in the individual DO
and so it is recommended that one of letters of the prefix on the instantiated LNs be set to “P” or “M” accordingly in order
to differentiate. For firmware versions 7.0 and later, only FCDA data is supported. The PMU Implementation by UR Device
table earlier indicates the maximum size of each PMU data set for version 7.2 and later using FCDA data (non-structured
data).
5.5.7.4 Example: Protection synchrophasors data set with reporting rate 60 frames/second
This example gives the protection synchrophasors data set with a reporting rate of 60 frames per second (P60MMXU1). See
the figure earlier, Logical Nodes Supported in Each Logical Device. This data or list of items, as shown in the following
figure, is not available to the UR setup program but is available to be mapped by the user into a selected aggregator or
aggregators dataset. The logical device name (LDName) of each PMU LD is a 64 character user setting. The IEEE C37.118
STN and IDCode is to be mapped as a concatenated value in the (d)escription field of LPL CDC of the NamPlt DO in LLN0.
The mapping is implemented as STN-IDCode (text string).
From each PMU, the user selects the phasor information of interest that is mapped into the selected aggregator datset(s).
For version 7.0 and later, only FCDA data is supported.

5.5.7.6 Configuration example: CFG-2 based configuration (using IEC 61850-90-5)
The G60 is expected to send the CFG-2 file (IEEE C37.118 config. file) upon request from the upstream synchrophasor
devices (for example, P30) without stopping R-SV multicasting, as shown in the following figure. The primary domain
controller (PDC) does not need to use a stop/start data stream command if the UR protocol is set to IEC 61850-90-5 prior to
requesting the configuration via CFG-2 (IEEE C37.118 config. file). The CFG-2 request from the P30 can be on TCP/IP or
UDP/IP, however, R-SV data streaming is only UDP multicasts (not TCP).

 90-5 PMU 1
 CONFIGURATION
See below
This section contains basic Phasor Measurement Unit (PMU) data, such as functions, source settings, and names.
PMU 1 FUNCTION — This setting enables the LOGICAL Device PMU 1 functionality. Use this setting to permanently enable or
disable the feature.
PMU 1 IDCODE — This setting assigns a numerical ID to the PMU. It corresponds to the IDCODE field of the data,
configuration, header, and command frames of the IEEE C37.118 protocol. The PMU uses this value when sending data,
configuration, and header frames; and it responds to this value when receiving the command frame. This is used when
only data from one PMU is present.
PMU 1 STN — This setting assigns an alphanumeric ID to the PMU station. It corresponds to the STN field of the
configuration frame of the IEEE C37.118 protocol. This value is a 16-character ASCII string as per the IEEE C37.118
standard.
PMU 1 SIGNAL SOURCE — This setting specifies one of the available G60 signal sources for processing in the PMU. Any
combination of voltages and currents can be configured as a source. The current channels can be configured as sums of
physically connected currents. This facilitates PMU applications in breaker-and-a-half, ring-bus, and similar arrangements.
The PMU feature calculates voltage phasors for actual voltage (A, B, C, and auxiliary) and current (A, B, C, and ground)
channels of the source, as well as symmetrical components (0, 1, and 2) of both voltages and currents. When configuring
communication and recording features of the PMU, the user can select, from the above superset, the content to be sent
out or recorded. When one source is selected by one PMU, it cannot be selected by another PMU.
PMU 1 CLASS (Range P, M, None) — This setting selects the synchrophasor class. A reporting rate of 100 or 120 can only be
5
selected for class P synchrophasors and if the system frequency is 50 or 60 Hz, respectively.
PMU 1 NETWORK REPORTING FORMAT — This setting selects between reporting synchrophasors as 16-bit integer or 32-bit
IEEE floating point numbers. This setting complies with bit-1 of the FORMAT field of the C37.118 configuration frame. Note
that this setting applies to synchrophasors only; the user-selectable FlexAnalog channels are always transmitted as 16-bit
integer values.
PMU 1 NETWORK REPORTING STYLE — This setting selects between reporting synchrophasors in rectangular (real and
imaginary) or in polar (magnitude and angle) coordinates. This setting complies with bit-0 of the FORMAT field of the
C37.118 configuration frame.
PMU 1 RATE — This setting specifies the reporting rate for the network (Ethernet) port. This value applies to all PMU streams
of the device that are assigned to transmit over this aggregator. For a system frequency of 60 Hz (50 Hz), the G60
generates a reporting mismatch message if the selected rate is not set as 10 Hz, 12 Hz, 15 Hz, 20 Hz, 30 Hz, 60 Hz, or 120
Hz (or 10 Hz, 25 Hz, 50 Hz, or 100 Hz when the system frequency is 50 Hz) when entered via the keypad or software; and
the G60 stops the transmission of reports. Note that 4 Hz is not allowed for an M-class 50 Hz system.
PMU 1 f & df/dt FILTER — This setting allows applying post-filtering to the frequency and rate-of-change of-frequency to
avoid reporting erroneous values, which can possibly happen during fault, switching, and other system disturbances. For
example, choosing 20Hz/s <10Hz setting ensures that if rate-of-change of-frequency between current reporting instance
and previous one exceeds 20Hz/s or frequency deviation from the nominal frequency exceeds 10Hz, then new frequency
and rate-of-change of-frequency value are invalidated. If this happens, the previous valid value of the frequency is
maintained and rate-of-change of-frequency value is forced to 0 at this reporting instance.
PMU 1 PHS-1 to PMU 1 PHS-14 — These settings specify synchrophasors to be transmitted from the superset of all
synchronized measurements. The table outlines available synchrophasor values.

These settings allow for optimizing the frame size and maximizing transmission channel usage, depending on a given
application. Select “Off” to suppress transmission of a given value.
PMU 1 PHS-1 NM to PMU 1 PHS-14 NM — These settings allow for custom naming of the synchrophasor channels. Sixteencharacter ASCII strings are allowed as in the CHNAM field of the configuration frame. These names are typically based on
station, bus, or breaker names.
PMU 1 A-CH-1 to PMU 1 A-CH-16 — These settings specify any analog data measured by the relay to be included as a user-
selectable analog channel of the data frame. Up to eight analog channels can be configured to send any FlexAnalog value
from the relay. Examples include frequency, rate of frequency change, active and reactive power, per phase or threephase power, power factor, temperature via RTD inputs, and THD. The configured analog values are sampled concurrently
with the synchrophasor instant and sent as 32-bit floating-point values scaled to Engineering units.
PMU 1 A-CH-1 NM to PMU 1 A-CH-16 NM — These settings allow for custom naming of the analog channels. Sixteen-character
ASCII strings are allowed as in the CHNAM field of the configuration frame.
PMU 1 D-CH-1 to PMU 1 D-CH-16 — These settings specify any digital flag measured by the relay to be included as a user-
selectable digital channel of the data frame. Up to 16 digital channels can be configured to send any FlexLogic operand
from the relay. The configured digital flags are sampled concurrently with the synchrophasor instant. These values are
mapped into a two-byte integer number, with byte 1 LSB corresponding to the digital channel 1 and byte 2 MSB
corresponding to digital channel 16.
PMU 1 D-CH-1 NM to PMU 1 D-CH-16 NM — These settings allow for custom naming of the digital channels. Sixteen-character
ASCII strings are allowed as in the CHNAM field of the configuration frame.
PMU 1 D-CH-1 NORMAL STATE to PMU 1 D-CH-16 NORMAL STATE — These settings allow for specifying a normal state for each
digital channel. These states are transmitted in configuration frames to the data concentrator.

This menu contains user angle and magnitude calibration data for the Phasor Measurement Unit (PMU). This data is
combined with the factory adjustments to shift the phasors for better accuracy.
PMU 1 VA... IG CALIBRATION ANGLE — These settings recognize applications with protection class voltage and current
sources, and they allow the user to calibrate each channel (four voltages and four currents) individually to offset errors
introduced by VTs, CTs, and cabling. The setting values are effectively added to the measured angles. Therefore, enter a
positive correction when the secondary signal lags the true signal and a negative value when the secondary signal leads
the true signal.
PMU 1 VA... IG CALIBRATION MAGNITUDE — These settings recognize applications with protection class voltage and current
sources, and they allow the user to calibrate each channel (four voltages and four currents) individually to offset errors
introduced by VTs, CTs. The setting values are effectively a multiplier of the measured magnitudes. Therefore, entering a
multiplier greater than 100% of the secondary signal increases the true signal, and a multiplier less than 100% value of the
secondary signal reduces the true signal.
PMU 1 SEQ VOLT SHIFT ANGLE — This setting allows correcting positive- and negative-sequence voltages for vector groups of
power transformers located between the PMU voltage point and the reference node. This angle is effectively added to the
positive-sequence voltage angle and subtracted from the negative-sequence voltage angle. Note that:
•
When this setting is not “0°”, the phase and sequence voltages do not agree. Unlike sequence voltages, the phase
voltages cannot be corrected in a general case and therefore are reported as measured.
•
When receiving synchrophasor data at multiple locations, with possibly different reference nodes, it can be more
beneficial to allow the central locations to perform the compensation of sequence voltages.
•
This setting applies to PMU data only. The G60 calculates symmetrical voltages independently for protection and
control purposes without applying this correction.
•
When connected to line-to-line voltages, the PMU calculates symmetrical voltages with the reference to the AG
voltage and not to the physically connected AB voltage (see the Metering Conventions section in Chapter 6).
PMU 1 SEQ CURR SHIFT ANGLE — This setting allows correcting positive and negative-sequence currents for vector groups of
power transformers located between the PMU current point and the reference node. The setting has the same meaning for
currents as the PMU 1 SEQ VOLT SHIFT ANGLE setting has for voltages. Normally, the two correcting angles are set identically,
except rare applications when the voltage and current measuring points are located at different windings of a power
transformer.

Each Phasor Measurement Unit (PMU) contains five triggering mechanisms to facilitate triggering of the associated PMU
recorder, or cross-triggering of other PMUs in the system. They are
•
Overfrequency and underfrequency
•
Overvoltage and undervoltage
•
Overcurrent
•
Overpower
•
High rate of change of frequency
The pre-configured triggers can be augmented with a user-specified condition built freely using programmable logic of the
relay. The entire triggering logic is refreshed once every two power system cycles.
All five triggering functions and the user-definable condition are consolidated (ORed) and connected to the PMU recorder.
Each trigger can be programmed to log its operation into the event recorder and to signal its operation via targets. The five
triggers drive the STAT bits of the data frame to inform the destination of the synchrophasor data regarding the cause of
trigger. The following convention is adopted to drive bits 11, 3, 2, 1, and 0 of the STAT word.

The trigger reset (drop-off) timer is available for all five triggering functions (FREQ, ROCOF, VOLT, CURR, POWER) in individual
trigger settings under the TRIGGER DPO TIME setting. This asserts individual trigger operand and overall PMU x TRIGGERED
operand with stat bits 3 and 11 for a fixed interval defined by this setting. If it is required that PMU x TRIGGERED operand with
stat bits 3 and 11 stay longer than the individual reset timer, then use the PMU x USER TRIGGER setting assigned with

The trigger responds to the frequency signal of the Phasor Measurement Unit (PMU) source. The frequency is calculated
from among phase voltages, auxiliary voltage, phase currents, and ground current, in this hierarchy, depending on the
source configuration as per G60 standards. This element requires that the frequency be above the minimum measurable
value. If the frequency is below this value, such as when the circuit is de-energized, the trigger drops out.
PMU 1 FREQ TRIGGER LOW-FREQ — Specifies the low threshold for the abnormal frequency trigger. The comparator applies a

This element responds to abnormal voltage. Separate thresholds are provided for low and high voltage. In terms of
signaling its operation, the element does not differentiate between the undervoltage and overvoltage events. The trigger
responds to the phase voltage signal of the Phasor Measurement Unit (PMU) source. All voltage channels (A, B, and C or AB,
BC, and CA) are processed independently and can trigger the recorder. A minimum voltage supervision of 0.1 pu is
implemented to prevent pickup on a de-energized circuit, similarly to the undervoltage protection element.
PMU 1 VOLT TRIGGER LOW-VOLT — Specifies the low threshold for the abnormal voltage trigger, in per-unit of the PMU

FLEXLOGIC
CHAPTER 5: SETTINGS
5.6 FlexLogic
5.6.1 FlexLogic operands
For flexibility, the arrangement of internal digital logic combines fixed and user-programmed parameters. Logic upon
which individual features are designed is fixed, and all other logic, from contact input signals through elements or
combinations of elements to contact outputs, is variable. The user has complete control of all variable logic through
FlexLogic. In general, the system receives analog and digital inputs that it uses to produce analog and digital outputs. The
figure shows major subsystems of a generic UR-series relay involved in this process.
Figure 5-99: UR architecture overview
5
The states of all digital signals used in the G60 are represented by flags (or FlexLogic operands, which are described later in
this section). A digital “1” is represented by a set flag. Any external contact change-of-state can be used to block an
element from operating, as an input to a control feature in a FlexLogic equation, or to operate a contact output. The state
of the contact input can be displayed locally or viewed remotely via the communications facilities provided. If a simple
scheme where a contact input is used to block an element is wanted, this selection is made when programming the
element. This capability also applies to the other features that set flags: elements, virtual inputs, remote inputs, schemes,
and human operators.
If more complex logic than shown in the figure is required, it is implemented via FlexLogic. For example, to have the closed
state of contact input H7a and the operated state of the phase undervoltage element block the operation of the phase
time overcurrent element, the two control input states are programmed in a FlexLogic equation. This equation ANDs the
two control inputs to produce a virtual output that is then selected when programming the phase time overcurrent to be
used as a blocking input. Virtual outputs can only be created by FlexLogic equations.
5-188
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
FLEXLOGIC
Traditionally, protective relay logic has been relatively limited. Any unusual applications involving interlocks, blocking, or
supervisory functions had to be hard-wired using contact inputs and outputs. FlexLogic minimizes the requirement for
auxiliary components and wiring while making more complex schemes possible.
The logic that determines the interaction of inputs, elements, schemes, and outputs is field-programmable through the use
of logic equations that are sequentially processed. The use of virtual inputs and outputs in addition to hardware is
available internally and on the communication ports for other relays to use (distributed FlexLogic).
FlexLogic allows users to customize the relay through a series of equations that consist of operators and operands. The
operands are the states of inputs, elements, schemes, and outputs. The operators are logic gates, timers, and latches (with
set and reset inputs). A system of sequential operations allows any combination of operands to be assigned as inputs to
specified operators to create an output. The final output of an equation is a numbered register called a virtual output.
Virtual outputs can be used as an input operand in any equation, including the equation that generates the output, as a
seal-in or other type of feedback.
A FlexLogic equation consists of parameters that are either operands or operators. Operands have a logic state of 1 or 0.
Operators provide a defined function, such as an AND gate or a Timer. Each equation defines the combinations of
parameters to be used to set a Virtual Output flag. Evaluation of an equation results in either a 1 (=ON, or flag set) or 0
(=OFF, or flag not set). Each equation is evaluated at least four times every power system cycle.
Some types of operands are present in the relay in multiple instances, for example contact and remote inputs. These types
of operands are grouped together (for presentation purposes only) on the front panel display. The table lists characteristics
of the different types of operands.

Notes
A ‘one shot’ refers to a single input gate that
generates a pulse in response to an edge on
the input. The output from a ‘one shot’ is
True (positive) for only one pass through the
FlexLogic equation. There is a maximum of
64 ‘one shots.’
5.6.2 FlexLogic rules
When forming a FlexLogic equation, the sequence in the linear array of parameters must follow these general rules:
1.
Operands must precede the operator that uses the operands as inputs.
2.
Operators have only one output. The output of an operator must be used to create a virtual output if it is to be used as
an input to two or more operators.
3.
Assigning the output of an operator to a virtual output terminates the equation.
4.
A timer operator (for example, "TIMER 1") or virtual output assignment (for example, " = Virt Op 1") can be used once

CHAPTER 5: SETTINGS
FLEXLOGIC
only. If this rule is broken, a syntax error is declared.
5.6.3 FlexLogic evaluation
Each equation is evaluated in the ascending order in which the parameters have been entered.
FlexLogic provides built-in latches that by definition have a memory action, remaining in the set state after the set
input has been asserted. These built-in latches are reset dominant, meaning that if logical "1" is applied to both set
and reset entries simultaneously, then the output of the latch is logical "0." However, they are volatile, meaning that
they reset upon removal of control power.
When making changes to FlexLogic entries in the settings, all FlexLogic equations are re-compiled whenever any
new FlexLogic entry value is entered, and as a result of the re-compile all latches are reset automatically.
To implement FlexLogic using a graphical user interface, see the FlexLogic Design and Monitoring using Engineer
section in the previous chapter.
5.6.4 FlexLogic example
This section provides an example of logic implementation for a typical application. The sequence of steps is important to
minimize the work to develop the relay settings. Note that the example in the following figure demonstrates the procedure,
not to solve a specific application situation.
Note that there is also a graphical interface with which to draw logic and populate FlexLogic equation entries. See the
Engineer content at the end of the previous chapter.
In the example, it is assumed that logic has already been programmed to produce virtual outputs 1 and 2, and is only a
part of the full set of equations used. When using FlexLogic, it is important to make a note of each virtual output used; a
virtual output designation (1 to 96) can be assigned only once.
Figure 5-100: Logic example
1.
Inspect the example logic diagram to determine if the required logic can be implemented with the FlexLogic
operators. If this is not possible, the logic must be altered until this condition is satisfied. Once done, count the inputs
to each gate to verify that the number of inputs does not exceed the FlexLogic limits, which is unlikely but possible. If
the number of inputs is too high, subdivide the inputs into multiple gates to produce an equivalent. For example, if 25
inputs to an AND gate are required, connect Inputs 1 through 16 to AND(16), 17 through 25 to AND(9), and the outputs
from these two gates to AND(2).
Inspect each operator between the initial operands and final virtual outputs to determine if the output from the
operator is used as an input to more than one following operator. If so, the operator output must be assigned as a
virtual output.

CHAPTER 5: SETTINGS
For the example shown, the output of the AND gate is used as an input to both OR#1 and Timer 1, and must therefore
be made a virtual output and assigned the next available number (that is, Virtual Output 3). The final output must also
be assigned to a virtual output as virtual output 4, which is programmed in the contact output section to operate relay
H1 (that is, contact output H1).
Therefore, the required logic can be implemented with two FlexLogic equations with outputs of virtual output 3 and
virtual output 4, shown as follows.
Figure 5-101: Logic example with virtual outputs

Prepare a logic diagram for the equation to produce virtual output 3, as this output is used as an operand in the virtual
output 4 equation (create the equation for every output that is used as an operand first, so that when these operands
are required they already have been evaluated and assigned to a specific virtual output). The logic for virtual output 3
is shown as follows with the final output assigned.

Program the FlexLogic equation for virtual output 3 by translating the logic into available FlexLogic parameters. The
equation is formed one parameter at a time until the required logic is complete. It is generally easier to start at the
output end of the equation and work back towards the input, as shown in the following steps. It is also recommended
to list operator inputs from bottom to top. For demonstration, the final outputs are arbitrarily identified as parameter
99, and each preceding parameter decremented by one in turn. Until accustomed to using FlexLogic, it is suggested
that a worksheet with a series of cells marked with the arbitrary parameter numbers be prepared shown as follows.
Figure 5-104: FlexLogic worksheet

Following the procedure outlined, start with parameter 99, as follows:
–
99: The final output of the equation is virtual output 3, which is created by the operator "= Virt Op n". This
parameter is therefore "= Virt Op 3".
–
98: The gate preceding the output is an AND, which in this case requires two inputs. The operator for this gate is a
2-input AND so the parameter is “AND(2)”. Note that FlexLogic rules require that the number of inputs to most
types of operators must be specified to identify the operands for the gate. As the 2-input AND operates on the
two operands preceding it, these inputs must be specified, starting with the lower.
–
97: This lower input to the AND gate must be passed through an inverter (the NOT operator) so the next
parameter is “NOT”. The NOT operator acts upon the operand immediately preceding it, so specify the inverter
input next.
–
96: The input to the NOT gate is to be contact input H1c. The ON state of a contact input can be programmed to
be set when the contact is either open or closed. Assume for this example that the state is to be ON for a closed
contact. The operand is therefore “Cont Ip H1c On”.

CHAPTER 5: SETTINGS
95: The last step in the procedure is to specify the upper input to the AND gate, the operated state of digital
element 2. This operand is "DIG ELEM 2 OP".
Writing the parameters in numerical order forms the equation for virtual output 3:
[95] DIG ELEM 2 OP
[96] Cont Ip H1c On
[97] NOT
[98] AND(2)
[99] = Virt Op 3
It is now possible to check that this selection of parameters produces the required logic by converting the set of
parameters into a logic diagram. The result of this process is shown in the figure, which is compared to the logic for
virtual output 3 diagram as a check.

Repeating the process described for virtual output 3, select the FlexLogic parameters for Virtual Output 4.
–
99: The final output of the equation is virtual output 4, which is parameter “= Virt Op 4".
–
98: The operator preceding the output is timer 2, which is operand “TIMER 2". Note that the settings required for
the timer are established in the timer programming section.
–
97: The operator preceding timer 2 is OR #2, a 3-input OR, which is parameter “OR(3)”.
–
96: The lowest input to OR #2 is operand “Cont Ip H1c On”.
–
95: The center input to OR #2 is operand “TIMER 1".
–
94: The input to timer 1 is operand “Virt Op 3 On".
–
93: The upper input to OR #2 is operand “LATCH (S,R)”.
–
92: There are two inputs to a latch, and the input immediately preceding the latch reset is OR #1, a 4-input OR,
which is parameter “OR(4)”.
–
91: The lowest input to OR #1 is operand “Virt Op 3 On".
–
90: The input just above the lowest input to OR #1 is operand “XOR(2)”.
–
89: The lower input to the XOR is operand “DIG ELEM 1 PKP”.
–
88: The upper input to the XOR is operand “Virt Ip 1 On".
–
87: The input just below the upper input to OR #1 is operand “Virt Op 2 On".
–
86: The upper input to OR #1 is operand “Virt Op 1 On".
–
85: The last parameter is used to set the latch, and is operand “Virt Op 4 On".
The equation for virtual output 4 is:
[85] Virt Op 4 On
[86] Virt Op 1 On
[87] Virt Op 2 On
[88] Virt Ip 1 On

Now write the complete FlexLogic expression required to implement the logic, making an effort to assemble the
equation in an order where Virtual Outputs that are used as inputs to operators are created before needed. In cases
where a lot of processing is required to perform logic, this can be difficult to achieve, but in most cases does not cause
problems as all logic is calculated at least four times per power frequency cycle. The possibility of a problem caused
by sequential processing emphasizes the necessity to test the performance of FlexLogic before it is placed in service.
In the following equation, virtual output 3 is used as an input to both latch 1 and timer 1 as arranged in the following
order:

In this expression, the virtual output 4 input to the four-input OR is listed before it is created. This is typical of a form of
feedback, in this case, used to create a seal-in effect with the latch, and is correct.

Always test the logic after it is loaded into the relay, in the same way as has been used in the past. Testing can be
simplified by placing an "END" operator within the overall set of FlexLogic equations. The equations are evaluated up
to the first "END" operator.
The "On" and "Off" operands can be placed in an equation to establish a known set of conditions for test purposes, and
the "INSERT" and "DELETE" commands can be used to modify equations.

A FlexElement is a universal comparator used to monitor any analog actual value calculated by the relay or a net
difference of any two analog actual values of the same type. The effective operating signal can be treated as a signed
number or its absolute value can be used.
FlexElements run every half power cycle (every four protection passes).
The element can be programmed to respond either to a signal level or to a rate-of-change (delta) over a pre-defined period
of time. The output operand is asserted when the operating signal is higher than a threshold or lower than a threshold, as
per your choice.

FLEXELEMENT 1 +IN — This setting specifies the first (non-inverted) input to the FlexElement. Zero is assumed as the input if
this setting is set to “Off.” For proper operation of the element, at least one input must be selected. Otherwise, the element
does not assert its output operands.
FLEXELEMENT 1 –IN — Specifies the second (inverted) input to the FlexElement. Zero is assumed as the input if this setting is
set to “Off.” For proper operation of the element, at least one input must be selected. Otherwise, the element does not
assert its output operands. This input is used to invert the signal if needed for convenience, or to make the element
respond to a differential signal, such as for a top-bottom oil temperature differential alarm. The element does not operate
if the two input signals are of different types, for example if one tries to use active power and phase angle to build the
effective operating signal.
The element responds directly to the differential signal if the FLEXELEMENT 1 INPUT MODE setting is set to “Signed” The
element responds to the absolute value of the differential signal if this setting is set to “Absolute.” Sample applications for
the “Absolute” setting include monitoring the angular difference between two phasors with a symmetrical limit angle in
both directions, monitoring power regardless of its direction, or monitoring a trend.
The element responds directly to its operating signal—as defined by the FLEXELEMENT 1 +IN, FLEXELEMENT 1 –IN and
FLEXELEMENT 1 INPUT MODE settings—if the FLEXELEMENT 1 COMP MODE setting is set to “Level.” The element responds to the
rate of change of its operating signal if the FLEXELEMENT 1 COMP MODE setting is set to “Delta.” In this case, the FLEXELEMENT
1 dt UNIT and FLEXELEMENT 1 dt settings specify how the rate of change is derived.
FLEXELEMENT 1 DIRECTION — Enables the relay to respond to either high or low values of the operating signal. The following

FLEXELEMENT 1 PICKUP — This setting specifies the operating threshold for the effective operating signal of the element. If

element picks up when the operating signal falls below the FLEXELEMENT 1 PICKUP value.
When using FlexElements for Voltage Elements, 1 pu is always equal to phase to ground voltage nominal secondary
voltage, even if you select a phase to phase voltage as an operating quantity.
FLEXELEMENT 1 HYSTERESIS — This setting controls the element dropout. Notice that both the operating signal and the
pickup threshold can be negative, facilitating applications such as reverse power alarm protection. The FlexElement can be

change protection settings for different operating situations (for example, altered power system configuration or season of

The following common settings are available for distance protection.
The DISTANCE SOURCE identifies the signal source for all distance functions. The mho distance functions use a dynamic
characteristic; the positive-sequence voltage—either memorized or actual—is used as a polarizing signal. The memory
voltage is also used by the built-in directional supervising functions applied for both the mho and quad characteristics.
The MEMORY DURATION setting specifies the length of time that a memorized positive-sequence voltage is used in the
distance calculations. After this interval expires, the relay checks the magnitude of the actual positive-sequence voltage. If
it is higher than 10% of the nominal, the actual voltage is used, and if lower the memory voltage continues to be used.
The memory is established when the positive-sequence voltage stays above 80% of its nominal value for five power
system cycles. For this reason, it is important to ensure that the nominal secondary voltage of the VT is entered correctly
under the SETTINGS  SYSTEM SETUP  AC INPUTS  VOLTAGE BANK menu.
Set MEMORY DURATION long enough to ensure stability on close-in reverse three-phase faults. For this purpose, consider the
maximum fault clearing time (breaker fail time) in the substation. On the other hand, the MEMORY DURATION cannot be too
long as the power system can experience power swing conditions rotating the voltage and current phasors slowly while
the memory voltage is static, as frozen at the beginning of the fault. Keeping the memory in effect for too long can
eventually lead to incorrect operation of the distance functions.

The distance zones can be forced to become self-polarized through the FORCE SELF-POLAR setting. Any user-selected
condition (any FlexLogic operand) can be configured to force self-polarization. When the selected operand is asserted
(logic 1), the distance functions become self-polarized regardless of other memory voltage logic conditions. When the
selected operand is de-asserted (logic 0), the distance functions follow other conditions of the memory voltage logic as
shown in the following logic diagram.
The distance zones can be forced to become memory-polarized through the FORCE MEM-POLAR setting. Any user-selected
condition (any FlexLogic operand) can be configured to force memory polarization. When the selected operand is asserted
(logic 1), the distance functions become memory-polarized regardless of the positive-sequence voltage magnitude at this
time. When the selected operand is de-asserted (logic 0), the distance functions follow other conditions of the memory
voltage logic.
Never let the FORCE SELF-POLAR and FORCE MEM-POLAR settings to be asserted simultaneously. If this happens, the logic
gives higher priority to forcing self-polarization as indicated in the logic diagram. This is consistent with the overall
philosophy of distance memory polarization.
The memory polarization cannot be applied permanently but for a limited time only. The self-polarization can be
applied permanently and therefore takes higher priority.
FAST DISTANCE enables the fast distance algorithm in phase and ground zone 1 and zone 2. Disable fast distance for
distance protection applications on a series compensated line.
PH DIST PH SELECT SUPV enables phase selection supervision on phase distance zone 1 to zone 3.

The phase mho distance function uses a dynamic 100% memory-polarized mho characteristic with additional reactance,
directional, and overcurrent supervising characteristics. When set to “Non-directional,” the mho function becomes an
offset mho with the reverse reach controlled independently from the forward reach, and all the directional characteristics
removed.
Each phase distance zone is configured individually through its own setting menu. All of the settings can be independently
modified for each of the zones except:
•
The SIGNAL SOURCE setting (common for the distance elements of all zones as entered under SETTINGS  GROUPED
ELEMENTS  SETTING GROUP 1(6)  DISTANCE)
•
The MEMORY DURATION setting (common for the distance elements of all zones as entered under SETTINGS 
GROUPED ELEMENTS  SETTING GROUP 1(6)  DISTANCE)
The common distance settings described earlier must be chosen properly for correct operation of the phase distance
elements.
Ensure that the Phase VT Secondary Voltage setting (see the SETTINGS  SYSTEM SETUP  AC INPUTS
 VOLTAGE BANK menu) is set correctly to prevent improper operation of associated memory
action.
PHS DIST Z1 DIR — All phase distance zones are reversible. The forward direction is defined by the PHS DIST Z1 RCA setting,
whereas the reverse direction is shifted 180° from that angle. The non-directional zone spans between the forward reach
impedance defined by the PHS DIST Z1 REACH and PHS DIST Z1 RCA settings, and the reverse reach impedance defined by
PHS DIST Z1 REV REACH and PHS DIST Z1 REV REACH RCA as illustrated in the following figures.

PHS DIST Z1 XFMR VOL CONNECTION — The phase distance elements can be applied to look through a three-phase delta-wye
or wye-delta power transformer. In addition, VTs and CTs can be located independently from one another at different
windings of the transformer. If the potential source is located at the correct side of the transformer, set this setting to
“None.”
This setting specifies the location of the voltage source with respect to the involved power transformer in the direction of
the zone. The following figure illustrates the usage of this setting. In section (a), zone 1 is looking through a transformer
from the delta into the wye winding. Therefore, the Z1 setting is set to “Dy11.” In section (b), Zone 3 is looking through a
transformer from the wye into the delta winding. Therefore, the Z3 setting is set to “Yd1.” The zone is restricted by the
potential point (location of the VTs) as illustrated in (e).
PHS DIST Z1 XFMR CUR CONNECTION — This setting specifies the location of the current source with respect to the involved
power transformer in the direction of the zone. In section (a) of the following figure, zone 1 is looking through a transformer
from the delta into the wye winding. Therefore, the Z1 setting is set to “Dy11.” In section (b), the CTs are located at the same
side as the read point. Therefore, the Z3 setting is set to “None.”

PHS DIST Z1 REACH — This setting defines the zone reach for the forward and reverse applications. In the non-directional
applications, this setting defines the forward reach of the zone. The reverse reach impedance in non-directional
applications is set independently. The reach impedance is entered in secondary ohms. The reach impedance angle is
entered as the PHS DIST Z1 RCA setting.
To achieve specified operating speed of distance elements, the relay internally calculates source to line impedance ratio
(SIR) from fault phasors. In these calculations, line impedance is estimated based on the zone 1 reach setting. Therefore, in
order to calculate the SIR value properly and to maintain the optimal operating speed of the distance elements, set zone 1
reach with a regular 80 to 85% of the line impedance reach setting, even when zone 1 is disabled.
PHS DIST Z1 RCA — This setting specifies the characteristic angle (similar to the "maximum torque angle" in previous
technologies) of the phase distance characteristic for the forward and reverse applications. In the non-directional
applications, this setting defines the angle of the forward reach impedance. The reverse reach impedance in the nondirectional applications is set independently. The setting is an angle of reach impedance as shown in the distance
characteristic figures earlier. This setting is independent from PHS DIST Z1 DIR RCA, the characteristic angle of an extra
directional supervising function.
PHS DIST Z1 REV REACH — This setting defines the reverse reach of the non-directional zone (PHS DIST Z1 DIR setting). The
value must be entered in secondary ohms. This setting does not apply when the zone direction is set to "Forward" or
"Reverse."
PHS DIST Z1 REV REACH RCA — This setting defines the angle of the reverse reach impedance of the non-directional zone
(PHS DIST Z1 DIR setting). This setting does not apply when the zone direction is set to "Forward" or "Reverse."

PHS DIST Z1 COMP LIMIT — This setting specifies the shape the operating characteristic, producing the lens-type
characteristic of the mho function. The same limit angle applies to both the mho and supervising reactance comparators.
This setting improves loadability of the protected line.
PHS DIST Z1 DIR RCA — This setting selects the characteristic angle (or maximum torque angle) of the directional supervising
function. The directional function is an extra supervising function as the dynamic mho characteristic itself is a directional
one. The directional function uses the memory voltage for polarization. This setting typically equals the distance
characteristic angle PHS DIST Z1 RCA.
PHS DIST Z1 DIR COMP LIMIT — Selects the comparator limit angle for the directional supervising function.
PHS DIST Z1 SUPV — The phase distance elements are supervised by the magnitude of the line-to-line current (fault loop
current used for the distance calculations). For convenience,
is accommodated by the pickup (that is, before being
used, the entered value of the threshold setting is multiplied by ).
If the minimum fault current level is sufficient, set the current supervision pickup above maximum full load current
preventing maloperation under VT fuse fail conditions. This requirement can be difficult to meet for remote faults at the
end of zones 2 and above. If this is the case, set the current supervision pickup below the full load current, but this can
result in maloperation during fuse fail conditions.
PHS DIST Z1 VOLT LEVEL — This setting is relevant for applications on series-compensated lines, or in general, if series
capacitors are located between the relaying point and a point where the zone does not overreach. For plain (noncompensated) lines, set to zero. Otherwise, the setting is entered in per unit of the phase VT bank configured under the
DISTANCE SOURCE. Effectively, this setting facilitates dynamic current-based reach reduction. In non-directional
applications (PHS DIST Z1 DIR set to “Non-directional”), this setting applies only to the forward reach of the non-directional
zone. See the Application of Settings chapter for information on calculating this setting for series compensated lines.
PHS DIST Z1 DELAY — This setting allows the user to delay operation of the distance elements and implement stepped
5
distance protection. The distance element timers for zones 2 and higher apply a short dropout delay to cope with faults
located close to the zone boundary when small oscillations in the voltages or currents can inadvertently reset the timer.
Zone 1 does not need any drop-out delay since it is sealed-in by the presence of current.
PHS DIST Z1 BLK — This setting enables the user to select a FlexLogic operand to block a given distance element. VT fuse fail
detection is one of the applications for this setting.

The power swing detect element provides both power swing blocking and out-of-step tripping functions. The element
measures the positive-sequence apparent impedance and traces its locus with respect to either two or three userselectable operating characteristic boundaries. Upon detecting appropriate timing relations, the blocking and/or tripping
indications are given through FlexLogic operands. The element incorporates an adaptive disturbance detector. This
function does not trigger on power swings, but is capable of detecting faster disturbances—faults in particular—that can
occur during power swings. Operation of this dedicated disturbance detector is signaled via the POWER SWING 50DD
operand.
The power swing detect element asserts two operands intended for blocking selected protection elements on power
swings: POWER SWING BLOCK is a traditional signal that is safely asserted for the entire duration of the power swing, and
POWER SWING UN/BLOCK is established in the same way, but resets when an extra disturbance is detected during the power
swing. The POWER SWING UN/BLOCK operand can be used for blocking selected protection elements if the intent is to
respond to faults during power swing conditions.
Different protection elements respond differently to power swings. If tripping is required for faults during power swing
conditions, some elements can be blocked permanently (using the POWER SWING BLOCK operand), and others can be
blocked and dynamically unblocked upon fault detection (using the POWER SWING UN/BLOCK operand).
5
View the operating characteristic and logic figures along with the following discussion to understand the operation of the
element.
The power swing detect element operates in three-step or two-step mode, as follows:
•
Three-step operation — The power swing blocking sequence essentially times the passage of the locus of the
positive-sequence impedance between the outer and the middle characteristic boundaries. If the locus enters the
outer characteristic (indicated by the POWER SWING OUTER FlexLogic operand) but stays outside the middle
characteristic (indicated by the POWER SWING MIDDLE FlexLogic operand) for an interval longer than POWER SWING
PICKUP DELAY 1, the power swing blocking signal (POWER SWING BLOCK FlexLogic operand) is established and sealed-in.
The blocking signal resets when the locus leaves the outer characteristic, but not sooner than the POWER SWING RESET
DELAY 1 time.
•
Two-step operation — If the two-step mode is selected, the sequence is identical to the three-step operation, but it is
the outer and inner characteristics that are used to time the power swing locus.
The out-of-step tripping feature operates as follows for three-step and two-step power swing detection modes:
•
Three-step operation — The out-of-step trip sequence identifies unstable power swings by determining if the
impedance locus spends a finite time between the outer and middle characteristics and then a finite time between
the middle and inner characteristics. The first step is similar to the power swing blocking sequence. After timer POWER
SWING PICKUP DELAY 1 times out, latch 1 is set as long as the impedance stays within the outer characteristic.
If afterwards, at any time (given the impedance stays within the outer characteristic), the locus enters the middle
characteristic but stays outside the inner characteristic for a period of time defined as POWER SWING PICKUP DELAY 2,
latch 2 is set as long as the impedance stays inside the outer characteristic. If afterwards, at any time (given the
impedance stays within the outer characteristic), the locus enters the inner characteristic and stays there for a period
of time defined as POWER SWING PICKUP DELAY 3, latch 2 is set as long as the impedance stays inside the outer
characteristic; the element is now ready to trip.
If the "Early" trip mode is selected, the POWER SWING TRIP operand is set immediately and sealed-in for the interval set
by the POWER SWING SEAL-IN DELAY. If the "Delayed" trip mode is selected, the element waits until the impedance locus
leaves the inner characteristic, then times out for the POWER SWING PICKUP DELAY 2 and sets latch 4; the element is
now ready to trip. The trip operand is set later, when the impedance locus leaves the outer characteristic.
•
Two-step operation — Similar to the three-step mode with two exceptions. First, the initial stage monitors the time
spent by the impedance locus between the outer and inner characteristics. Second, the stage involving the POWER
SWING PICKUP DELAY 2 timer is bypassed. It is up to the user to integrate the blocking (POWER SWING BLOCK) and tripping

operand triggers on faults occurring during power swing conditions. This includes both three-phase and single-poleopen conditions.

POWER SWING FUNCTION — This setting enables and disables the power swing detection element. The setting applies to
both power swing blocking and out-of-step tripping functions.
POWER SWING SOURCE — The source setting identifies the signal source for both blocking and tripping functions.
POWER SWING SHAPE — This setting selects the shapes (either “Mho” or “Quad”) of the outer, middle, and inner
characteristics of the power swing detect element. The operating principle is not affected. The “Mho” characteristics use
the left and right blinders.

G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS
GROUPED ELEMENTS
POWER SWING MODE — This setting selects between the two-step and three-step operating modes and applies it to both
power swing blocking and out-of-step tripping functions. The three-step mode applies if there is enough space between
the maximum load impedances and distance characteristics of the relay that all three (outer, middle, and inner)
characteristics can be placed between the load and the distance characteristics. Whether the spans between the outer
and middle as well as the middle and inner characteristics are sufficient is determined by analysis of the fastest power
swings expected in correlation with settings of the power swing timers.
The two-step mode uses only the outer and inner characteristics for both blocking and tripping functions. This leaves more
space in heavily loaded systems to place two power swing characteristics between the distance characteristics and the
maximum load, but allows for only one determination of the impedance trajectory.
POWER SWING SUPV — A common overcurrent pickup level supervises all three power swing characteristics. The
supervision responds to the positive-sequence current.
POWER SW I2 SUPV ENAB — This setting is to enable I2 supervision logic through a FlexLogic operand, which is used to
detect the presence of significant unbalance in current signals, such as during fault conditions. Under these conditions, the
POWER SWING BLOCK operand is not asserted.
POWER SWING I2 SUPV — This setting specifies the threshold of the I2 supervision logic.
POWER SWING FWD REACH — This setting specifies the forward reach of all three mho characteristics and the inner
quadrilateral characteristic. For a simple system consisting of a line and two equivalent sources, this reach needs to be
higher than the sum of the line and remote source positive-sequence impedances. Detailed transient stability studies can
be needed for complex systems in order to determine this setting. The angle of this reach impedance is specified by the
POWER SWING FWD RCA setting.
POWER SWING QUAD FWD REACH MID — This setting specifies the forward reach of the middle quadrilateral characteristic.
The angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if the shape
setting is “Mho.”
POWER SWING QUAD FWD REACH OUT — This setting specifies the forward reach of the outer quadrilateral characteristic.
The angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if the shape
setting is “Mho.”
POWER SWING FWD RCA — This setting specifies the angle of the forward reach impedance for the mho characteristics,
angles of all blinders, and both forward and reverse reach impedances of the quadrilateral characteristics.
POWER SWING REV REACH — This setting specifies the reverse reach of all three mho characteristics and the inner
quadrilateral characteristic. For a simple system of a line and two equivalent sources, this reach needs to be higher than
the positive-sequence impedance of the local source. Detailed transient stability studies can be needed for complex
systems to determine this setting. The angle of this reach impedance is specified by the POWER SWING REV RCA setting for
“Mho,” and the POWER SWING FWD RCA setting for inner “Quad.”
POWER SWING QUAD REV REACH MID — This setting specifies the reverse reach of the middle quadrilateral characteristic.
The angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if the shape
setting is “Mho.”
POWER SWING QUAD REV REACH OUT — This setting specifies the reverse reach of the outer quadrilateral characteristic. The
angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if the shape
setting is “Mho.”
POWER SWING REV RCA — This setting specifies the angle of the reverse reach impedance for the mho characteristics. This
setting applies to mho shapes only.
POWER SWING OUTER LIMIT ANGLE — This setting defines the outer power swing characteristic. The convention depicted in
the power swing detect mho operating characteristic diagram are to be observed: values greater than 90° result in an
apple-shaped characteristic; values less than 90° result in a lens-shaped characteristic. This angle must be selected in
consideration of the maximum expected load. If the maximum load angle is known, coordinate the outer limit angle with a
20° security margin. Detailed studies can be needed for complex systems to determine this setting. This setting applies to
mho shapes only.
POWER SWING MIDDLE LIMIT ANGLE — This setting defines the middle power swing detect characteristic. It is relevant only
for the three-step mode. A typical value is close to the average of the outer and inner limit angles. This setting applies to
mho shapes only.

GROUPED ELEMENTS
CHAPTER 5: SETTINGS
POWER SWING INNER LIMIT ANGLE — This setting defines the inner power swing detect characteristic. The inner
characteristic is used by the out-of-step tripping function: beyond the inner characteristic out-of-step trip action is definite
(the actual trip can be delayed as per the TRIP MODE setting). Therefore, this angle must be selected in consideration to the
power swing angle beyond which the system becomes unstable and cannot recover.
The inner characteristic is also used by the power swing blocking function in the two-step mode. In this case, set this angle
large enough so that the characteristics of the distance elements are safely enclosed by the inner characteristic. This
setting applies to mho shapes only.
POWER SWING OUTER, MIDDLE, and INNER RGT BLD — These settings specify the resistive reach of the right blinder. The
blinder applies to both “Mho” and “Quad” characteristics. Set these value high if no blinder is required for the “Mho”
characteristic.
POWER SWING OUTER, MIDDLE, and INNER LFT BLD — These settings specify the resistive reach of the left blinder. Enter a
positive value; the relay automatically uses a negative value. The blinder applies to both “Mho” and “Quad” characteristics.
Set this value high if no blinder is required for the “Mho” characteristic.
POWER SWING PICKUP DELAY 1 — All the coordinating timers are related to each other and need to be set to detect the
fastest expected power swing and produce out-of-step tripping in a secure manner. Set the timers in relation to the power
swing detect characteristics, mode of power swing detect operation, and mode of out-of-step tripping. This timer defines
the interval that the impedance locus must spend between the outer and inner characteristics (two-step operating mode),
or between the outer and middle characteristics (three-step operating mode) before the power swing blocking signal is
established. This time delay must be set shorter than the time required for the impedance locus to travel between the two
selected characteristics during the fastest expected power swing. This setting is relevant for both power swing blocking
and out-of-step tripping.
5
POWER SWING RESET DELAY 1 — This setting defines the dropout delay for the power swing blocking signal. Detection of a
condition requiring a block output sets latch 1 after PICKUP DELAY 1 time. When the impedance locus leaves the outer
characteristic, timer POWER SWING RESET DELAY 1 is started. When the timer times-out, the latch is reset. Select this setting
to give extra security for the power swing blocking action.
POWER SWING PICKUP DELAY 2 — Controls the out-of-step tripping function in the three-step mode only. This timer defines
the interval the impedance locus must spend between the middle and inner characteristics before the second step of the
out-of-step tripping sequence is completed. This time delay must be set shorter than the time required for the impedance
locus to travel between the two characteristics during the fastest expected power swing.
POWER SWING PICKUP DELAY 3 — Controls the out-of-step tripping function only. It defines the interval the impedance locus
must spend within the inner characteristic before the last step of the out-of-step tripping sequence is completed and the
element is armed to trip. The actual moment of tripping is controlled by the TRIP MODE setting. This time delay is provided
for extra security before the out-of-step trip action is executed.
POWER SWING PICKUP DELAY 4 — Controls the out-of-step tripping function in “Delayed” trip mode only. This timer defines
the interval the impedance locus must spend outside the inner characteristic but within the outer characteristic before the
element is armed for the delayed trip. The delayed trip occurs when the impedance leaves the outer characteristic. This
time delay is provided for extra security. Set it considering the fastest expected power swing.
POWER SWING SEAL-IN DELAY — The out-of-step trip FlexLogic operand (POWER SWING TRIP) is sealed-in for the specified
period of time. The sealing-in is crucial in the delayed trip mode, as the original trip signal is a very short pulse occurring
when the impedance locus leaves the outer characteristic after the out-of-step sequence is completed.
POWER SWING TRIP MODE — Selection of the “Early” trip mode results in an instantaneous trip after the last step in the outof-step tripping sequence is completed. The early trip mode stresses the circuit breakers as the currents at that moment
are high (the electromotive forces of the two equivalent systems are approximately 180° apart). Selection of the “Delayed”
trip mode results in a trip at the moment when the impedance locus leaves the outer characteristic. Delayed trip mode
relaxes the operating conditions for the breakers as the currents at that moment are low. Make the selection considering
the capability of the breakers in the system.
POWER SWING BLK — This setting specifies the FlexLogic operand used for blocking the out-of-step function only. The
power swing blocking function is operational all the time as long as the element is enabled. The blocking signal resets the
output POWER SWING TRIP operand but does not stop the out-of-step tripping sequence.
POWER SWING EVENTS — Enables and disables the logging of power swing detect events in the sequence of events
recorder.

The stator differential protection element is intended for use on the stator windings of rotating machinery.
Figure 5-126: Stator differential characteristic
This element has a dual slope characteristic. The main purpose of the percent-slope characteristic is to prevent a
maloperation caused by unbalances between CTs during external faults. CT unbalances arise as a result of the following
factors:
•
CT accuracy errors
•
CT saturation
G60 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL

GROUPED ELEMENTS
CHAPTER 5: SETTINGS
The characteristic allows for very sensitive settings when fault current is low and less sensitive settings when fault current
is high and CT performance can produce incorrect operate signals.
STATOR DIFF LINE END SOURCE — This setting selects the source connected to CTs in the end of the machine stator winding
closest to the load and farthest from the winding neutral point. Wire both line and neutral-side CTs to measure their
currents in the same direction with respect to the neutral point of the winding.
STATOR DIFF NEUTRAL END SOURCE — Selects the source connected to CTs in the end of the machine stator winding farthest
from the load and closest to the winding neutral point. Wire both line and neutral-side CTs to measure their currents in the
same direction with respect to the neutral point of the winding.
STATOR DIFF PICKUP — Defines the minimum differential current required for operation. This setting is based on the amount
of differential current that can be seen under normal operating conditions. A setting of 0.1 to 0.3 pu is generally
recommended.
STATOR DIFF SLOPE 1 — This setting is applicable for restraint currents from zero to STATOR DIFF BREAK 1, and it defines the
ratio of differential to restraint current above which the element operates. This slope is set to ensure sensitivity to internal
faults at normal operating current levels. The criteria for setting this slope is to allow for maximum expected CT mismatch
error when operating at the maximum permitted current. This maximum error is generally in the range of 5 to 10% of CT
rating.
STATOR DIFF BREAK 1 — Defines the end of the Slope 1 region and the start of the transition region. Set it just above the
maximum normal operating current level of the machine.
5
STATOR DIFF SLOPE 2 — This setting is applicable for restraint currents above the STATOR DIFF BREAK 2 setting when the
element is applied to generator stator windings. This slope is set to ensure stability under heavy external fault conditions
that can lead to high differential currents as a result of CT saturation. A setting of 80 to 100% is recommended. The
transition region (as shown on the characteristic plot) is a cubic spline, automatically calculated by the relay to result in a
smooth transition between STATOR DIFF SLOPE 1 and STATOR DIFF SLOPE 2 with no discontinuities.
STATOR DIFF BREAK 2 — This setting defines the end of the transition region and the start of the Slope 2 region. Set it to the
level at which any of the protection CTs are expected to begin to saturate.

5.7.5.1 Saturation detection
External faults near generators typically result in very large time constants of DC components in the fault currents. Also,
when energizing a step-up transformer, the inrush current being limited only by the machine impedance can be
significant and can last for a very long time. In order to provide additional security against maloperations during these

CHAPTER 5: SETTINGS
GROUPED ELEMENTS
events, the G60 incorporates saturation detection logic. When saturation is detected, the element makes an additional
check on the angle between the neutral and output current. If this angle indicates an internal fault, then tripping is
permitted.
The saturation detector is implemented as a state machine (see figure). "NORMAL" is the initial state of the machine. When
in "NORMAL" state, the saturation flag is not set (SAT = 0). The algorithm calculates the saturation condition, SC. If SC = 1
while the state machine is "NORMAL," the saturation detector goes into the "EXTERNAL FAULT" state and sets the saturation
flag (SAT = 1). The algorithm returns to the "NORMAL" state if the differential current is below the first slope, SL, for more
than 200 ms. When in the "EXTERNAL FAULT" state, the algorithm goes into the "EXTERNAL FAULT & CT SATURATION" state if
the differential flag is set (DIF = 1). When in the "EXTERNAL FAULT & CT SATURATION" state, the algorithm keeps the
saturation flag set (SAT = 1). The state machine returns to the "EXTERNAL FAULT" state if the differential flag is reset (DIF = 0)
for 100 ms.

5.7.5.2 Phase comparison principle
The test for direction can be summarized by the following equation:
If (|ITS| > BL or (|ITS| > K x IR and |ITS| > 0.1 pu)) and (|INS| > BL or (|INS| > K x IR and |INS| > 0.1 pu))
Eq. 5-8
Then
If abs (ITS - INS) > 90°, DIR = 1
Otherwise DIR = 0
else DIR = 1
meaning that if there are fault current contributors from both terminal and neutral sides, angles between currents are
checked. If there is just one contributor, angles are not checked and phase comparison check is bypassed (DIR=1).
where
IR = restraining current
DIR = flag indicating that the phase comparison principle is satisfied
BL = breakpoint 1 setting
ITS, INS = current at the terminal and neutral sources, respectively
K = factory constant of 0.25

5.7.6.2 Inverse TOC curve characteristics
The inverse time overcurrent curves used by the time overcurrent elements are the IEEE, IEC, GE Type IAC, and I2t standard
curve shapes. This allows for simplified coordination with downstream devices.
If none of these curve shapes is adequate, FlexCurves can be used to customize the inverse time curve characteristics. The
definite time curve is also an option that can be appropriate if only simple protection is required.

Definite Time
A time dial multiplier setting allows selection of a multiple of the base curve shape (where the time dial multiplier = 1) with
the curve shape (CURVE) setting. Unlike the electromechanical time dial equivalent, operate times are directly proportional
to the time multiplier (TD MULTIPLIER) setting value. For example, all times for a multiplier of 10 are 10 times the multiplier 1
or base curve values. Setting the multiplier to zero results in an instantaneous response to all current levels above pickup.

CHAPTER 5: SETTINGS
GROUPED ELEMENTS
Time overcurrent time calculations are made with an internal energy capacity memory variable. When this variable
indicates that the energy capacity has reached 100%, a time overcurrent element operates. If less than 100% energy
capacity is accumulated in this variable and the current falls below the dropout threshold of 97 to 98% of the pickup value,
the variable must be reduced. Two methods of this resetting operation are available: “Instantaneous” and “Timed.” The
“Instantaneous” selection is intended for applications with other relays, such as most static relays, which set the energy
capacity directly to zero when the current falls below the reset threshold. The “Timed” selection can be used where the
relay must coordinate with electromechanical relays.
The URs calculate operate time corresponding to the values in the range of 1.03 to 20 multiples of the pickup current.
Above 20 multiples of the pickup current, URs clamp the operate time to the value at a multiple of 20, resulting in the flat
part of the characteristics. Reset time is calculated in the range of 0 to 0.97 multiples of the pickup current.
IEEE curves
The IEEE time overcurrent curve shapes conform to industry standards and the IEEE C37.112-1996 curve classifications for
extremely, very, and moderately inverse curves. The IEEE curves are derived from the operate and reset time equations.

IAC curves
The curves for the General Electric type IAC relay family are derived from the formulae:
Eq. 5-11
where
T = operate time (in seconds)
TDM = Multiplier setting
I = Input current
Ipkp = Pickup Current setting
A to E = constants defined in the table
tr = characteristic constant defined in the table
TRESET = reset time in seconds (assuming energy capacity is 100% and RESET is “Timed”)
