Application area also covers protection functions for a large variety of applications, e.g.
frequency and voltage based protection,
motor protection, thermal overload protection, capacitor bank protection and synchrocheck/voltage check function.
In addition to protection, measurement, control and condition monitoring functions, the
feeder terminals are provided with a large
amount of PLC functions allowing several
automation and sequence logic functions
needed for substation automation to be integrated into one unit.
The data communication properties include
the following communications: SPA bus,
LON bus, IEC 60870-5-103, IEC 61850,
Profibus-DPV1, DNP 3.0 or Modbus communication with higher-level equipment. Further, LON communication, together with
PLC functions, minimizes the need for hardwiring between the units.

Distributed protection and control system
based on REF 54_ feeder terminals.
The feeder terminals REF 541, REF 543 and
REF 545 differ from each other regarding the
number of digital inputs and outputs available. Please, refer to section “Ordering” for
more details.
The REF 54_ feeder terminals incorporate a
wide range of feeder terminal functions:
• Protection functions
• Measurement functions
• Disturbance recorder
• Power quality functions
• Control functions
• Fault locator
• Condition monitoring functions
• General functions
• Communication functions
• Standard functions
The function blocks are documented on the
CD-ROM “Technical Descriptions of Functions” (1MRS 750889-MCD).

Protection functions
Protection is one of the most important functions of the REF 54_ feeder terminal. The
protection function blocks (e.g. NOC3Low)
are independent of each other and have e.g.
their own setting groups and data recording.
The non-directional overcurrent protection
includes e.g. the three stages NOC3Low,
NOC3High and NOC3Inst, each with independent protection functions.
Either Rogowski coils or conventional current transformers can be used for protection
functions based on current measurement.
Correspondingly, voltage dividers or voltage
transformers are used for protection functions
based on voltage measurement
For further information about functionality
levels and the protection functions included
in them, refer to the table “Functionality levels, protection functions” in section
“Ordering”.
Measurement functions
The measurement functions include threephase currents, neutral current, three-phase
voltages, residual voltage, frequency, active
Feeder Terminal
REF 541, REF 543, REF 545.
1MRS750443-MBG
and reactive power and power factor. In addition, other measurement functions are available.
As a standard feature the REF 54_ terminal
includes pulse counter inputs. The number of
pulse inputs varies from 7 (REF 541) to 10
(REF 545) according to the REF variant.
Disturbance recorder
The transient disturbance recorder is able to
record 16 current or voltage waveforms and
16 logic digital signals. The sampling frequency of the analogue inputs is 2 kHz at the
rated frequency of 50 Hz and 2.4 kHz at the
rated frequency of 60 Hz.
The user can set the length of a recording
within a range determined by the number of
analogue inputs used. The number of recordings depends on the sampling frequency,
length of recordings and number of analogue
inputs.
The recordings can be uploaded with a DRCollector Tool which converts the data to a
COMTRADE format. The DR-Collector Tool
is supported in CAP501 and CAP505 relay
tools.
MIMIC configuration picture displayed on
the HMI. Position indicators are used to indicate the position of switching devices via the
MIMIC picture and to control them locally.
The status of different objects, e.g. open/
close/undefined, displayed in the MIMIC
view can be freely designed.
Fault locator
The fault locator function for radial distribution systems. Short-circuit localization in all
kind of distribution networks. Earth-fault
localization in effectively earthed networks
and in low reactance/low resistance earthed
networks. Assists fast power restoration after
the fault. Improves system availability and
performance.
Condition monitoring functions
Condition monitoring function blocks such as
supervision of the energizing current and
voltage input circuit, operation time counter,
circuit breaker electric wear, scheduled maintenance, trip circuit supervision and breaker
travel time are available for the REF 54_
feeder terminals.
General functions
Power quality functions
Power quality functions enable measurement
of total harmonic distortion (THD) of voltage
and current, and total demand distortion
(TDD) of current. Individual harmonics are
measured up to 13th.
Power quality functions also include measurement of short duration voltage variations
like sags, swells and short interruptions. Measurements are done according to the IEC standard 61000-4-30.
LIB 510 supports tools for presentation of
harmonics and short duration voltage variations.
Control functions
The control functions are used to indicate the
position of switching devices, i.e. circuit
breakers and disconnectors, and to execute
open and close commands for controllable
switching devices in the switchgear. Furthermore, there are supplementary functions for
control logic purposes, e.g. on/off switches,
MIMIC alarm, LED control, numerical data
for the MIMIC and logic controlled position
selection.
The control functions configured using the
Relay Configuration Tool can be associated
with position indicators that are part of the
Additional functions are available for different general purposes to be used in logics such
as activation of HMI backlight, switchgroups,
and resetting of operation indications, latched
output signals, registers and disturbance
recorder.
Communication functions
The REF 54_ feeder terminal provides the
IEC 60870-5-103, IEC 61850, ProfibusDPV1, Modbus, DNP 3.0, SPA and LON
serial communication protocols.
In a customer-specific feeder terminal configuration, special events can be generated via
an EVENT230 event function.
Standard functions
Standard functions are used for logics such as
interlocking, alarming and control sequencing. The use of logic functions is not limited
and the functions can be interconnected with
each other as well as with protection, measurement, power quality, control, condition
monitoring and general functions. In addition,
the digital inputs and outputs as well as LON
inputs and outputs can be connected to standard functions by using the Relay Configuration Tool.

Other functions
Low auxiliary voltage indication
The REF 54_ feeder terminal is provided
with a low auxiliary voltage indication feature. The power supply module issues an
internal alarm signal when a drop in the
power supply voltage is detected (ACFail,
active low). The alarm signal is activated if
the power supply voltage falls about 10%
below the lowest rated DC input voltage of
the power supply module.
The indication of a low auxiliary voltage is
available in the feeder terminal configuration
and can be connected to any signal output of
the REF 54_.
Overtemperature indication
The REF 54_ feeder terminal includes an
internal temperature supervision function.
The power supply module issues an internal
alarm signal when overtemperature has been
detected inside the terminal enclosure. The
alarm signal will be activated once the temperature inside the terminal enclosure
increases to +78°C (+75°...+83°C). Overtemperature indication is available in the
feeder terminal configuration and can be connected to any signal output of the terminal.
Analog channels
The feeder terminal measures the analogue
signals needed for protection, measuring, etc.
via sensors or galvanically separated matching transformers.
Depending on whether sensors are included
or not, REF 54_ feeder terminals have 9
(without sensors) or 10 (with sensors) analogue channels. The number of channels used
depends on the feeder terminal configuration
and the kind of matching transformers or sensor inputs used. Furthermore, the feeder terminal includes virtual analogue channels for
calculating the phase-to-phase voltages, neutral current and residual voltage from phase
currents and voltages.
In addition to 9 conventional matching transformers, sensors developed by ABB can be
used parallel in REF 54_ feeder terminals.
The feeder terminal has 9 sensor inputs. A
current sensor (Rogowski coil) or a voltage
divider can be connected to each sensor input.
Please, see the connection diagram for
details. When ordering, please note the type
of analogue inputs.
6
Each analog channel is separately configured
with the Relay Configuration Tool. Both the
measuring unit for each analog channel and
the type of signal to be measured are to be
configured.
A separate scaling factor can be set for each
analogue channel. The factors enable differences between the ratings of the protected
unit and those of the measuring device (CTs,
VTs etc.). The setting value 1.00 means that
the rated value of the protected unit is exactly
the same as that of the measuring device.
Calculated analogue channels
The REF 54_ feeder terminal includes virtual
channels to obtain phase-to-phase voltages,
neutral current and residual voltage when
sensors are used. Sensors are connected to the
feeder terminal via coaxial cables and therefore a residual connection of phase currents
or an open-delta connection of phase voltages
cannot be made. Both the amplitude and the
phase angle are calculated for the virtual
channels.
Though primarily meant to be used with sensors, the calculated analogue channels can
also be used with conventional current and
voltage transformers.
Note! When sensitive earth-fault protection is
needed, core balance transformers are not
recommended to be replaced with the numerically derived sum of phase currents. Normally, an earth-fault setting below 10% of the
rated value requires the use of a core balance
transformer.
Digital inputs
The digital inputs of the feeder terminals are
voltage-controlled and optically isolated. The
function of a digital input can be inverted.
The programmable filter time removes
debounces and short disturbances on a digital
input. The filter time can be set for each digital input separately.
Some specific digital inputs can be programmed to operate either as digital inputs, as
pulse counters or as used for time synchronization. When a digital input operates as a
pulse counter, pulse counting frequency can
be up to100 Hz.
Oscillation suppression
The feeder terminals have two global parameters for the suppression of digital input oscillation. The settings of these parameters
Feeder Terminal
REF 541, REF 543, REF 545.
1MRS750443-MBG
determine the oscillation level and hysteresis
for all digital inputs. Event is generated in
case oscillation is detected.
Attributes of a digital input for feeder terminal configuration
For each digital input, the status of the input
(value), the time tag for the status change
(time) and the validity of the digital input
(invalidity) can be issued by the attributes.
These attributes are available in the feeder
terminal configuration and can be used for
various purposes.
RTD/analogue inputs
The REF 541 and REF 543 feeder terminals
equipped with an RTD/analogue module
(RTD1) have eight general purpose analogue
inputs for DC measurement. The RTD/analogue inputs are galvanically isolated from
the feeder terminal power supply and enclosure. However, the inputs have a common
ground. The general purpose RTD/analogue
inputs accept voltage-, current- or resistancetype signals. For each measuring mode, a
separate parameter is provided for choosing
between the available measurement ranges.
RTD/analogue inputs can be applied for e.g.
temperature measurement.
Digital outputs
The outputs of the feeder terminal are categorized as follows:
• HSPO: High-speed power output, doublepole contact, preferred for tripping purposes and for circuit breaker and disconnector control
• PO: Power output, either single-pole or
double-pole contact, preferred for circuit
breaker and disconnector control
• SO: Signal output, either NO (Normally
Open) or NO/NC (Normally Open/Normally Closed) contact. The output contact
is a normal-duty contact and cannot be
used for controlling a heavy load such as a
circuit breaker.
Analogue outputs
The REF 541 and REF 543 feeder terminals
equipped with an RTD/analogue module have
four general purpose 0...20 mA analogue current outputs. All outputs are galvanically isolated from the supply and enclosure of the
feeder terminal and from each other.
Analogue outputs can be utilized for transferring any measured or calculated information
to panel meters or e.g. PLCs.
Alarm LED indicators
The feeder terminal offers eight alarm LED
indicators to be configured with the Relay
Mimic Editor. The LED colours (green, yellow, red), their use, and the ON and OFF state
texts can be freely defined. Three basic operation modes are supported: non-latched,
latched-steady and latched flashflashing.
Alarms can be acknowledged remotely,
locally or by using logic of the feeder terminal.
The alarm channels include time tagging for
detected alarms. The time tagging principle
used depends on the operation mode.
Interlocking LED indicator
The interlocking LED indicates that control
operation has been interlocked or that the
interlocking is in bybass mode, e.g. when
control is possible despite of interlocking.
Trip Circuit Supervision
The purpose of this function is to supervise
the tripping circuitry of the circuit breaker.
An alarm will be generated in case a faulty
tripping circuit, e.g. a circuit is not able to
perform a trip, is detected.
The supervision is based on the constant-current injection through the tripping circuitry.
Display panel
The feeder terminal is provided with either a
fixed display or an external display module.
The external display module requires a separate voltage supply from a common source
with the main unit. The display consists of 19
rows divided into two windows: a main window (17 rows) and an assisting window
(2 rows).
The graphic display presents detailed information on MIMIC, objects, events, measurements, control alarms, and parameters. The
assisting window is used for terminal-dependent indications/alarms and help messages.
Additionally, the panel includes the following
HMI items:
• three push-buttons for object control (I, O,
object selection)
• eight freely programmable alarm LEDs
with different colours and modes according to the configuration
• LED indicator for control interlocking
• three protection LED indicators
• HMI push-button section with four arrow
buttons and buttons for clear and enter

terminal
• a button for remote/local control
HMI has two main levels, the user level and
the technical level. The user level is for
“everyday” measurements and monitoring
whereas the technical level is intended for
advanced feeder terminal programming.
Serial communication
The feeder terminal has three serial communication ports, one on the front panel and two
on the rear panel.
Front panel optical connection for PC
The front panel is intended for the connection
of a PC for configuring the feeder terminal
with the CAP 50_ tools. The front interface
uses the SPA bus protocol.
The optical connector on the front panel isolates the PC galvanically from the feeder terminal. The front connector for the PC is
standardized for ABB relay products and
requires a specific opto cable. The cable is
connected to the serial RS-232 port of the PC.
The other communication parameters for the
rear RS-485 interface are also set in the Communication menu of the REF 54_ feeder terminal.
SPA/IEC_103 communication on the rear
connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear panel
connects the feeder terminal to the distribution automation system via the SPA bus or the
IEC_103. The fibre-optic interface module
type RER 123 is used for connecting the
feeder terminal to the fibre-optic communication bus for SPA and IEC_103 protocol.
DNP3.0/Modbus communication on the
rear connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear panel
connects the feeder terminal to the distribution automation system via the DNP 3.0 or
the Modbus protocol. The interface between
the feeder terminal and a RS-485 communication bus can be made through the RER 133
Bus Connection Module. The interface
between the feeder terminal and an optical
bus can be made through the RER 123 Bus
Connection Module.
8
IEC 61850 communication using SPA-ZC
400 on the rear connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear panel
connects the feeder terminal to the distribution automation system via the IEC 61850
protocol. In the IEC 61850 mode, the SPAZC 400 Bus Connection Module is needed.
Profibus-DPV1 communication using SPAZC 302 on the rear connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear panel
connects the feeder terminal to the distribution automation system via the Profibus protocol. The interface between the feeder
terminal and Profibus can be made through
the SPA-ZC 302 Gateway.
LON/SPA bus communication on the rear
connector X3.3
The 9-pin D-type subminiature female connector (RS-485 connection) on the rear panel
connects the feeder terminal to the substation
automation system via the SPA bus or the
LON bus. The fibre-optic interface module
type RER 103 is used to connect the feeder
terminal to the fibre-optic communication
bus. The RER 103 module supports both SPA
bus and LON bus communication.
Self-supervision
The feeder terminal REF 54_ is provided
with an extensive self-supervision system.
The self-supervision system handles run-time
fault situations and informs the user of faults
via the HMI and LON/SPA bus communication.
When a fault has been detected, the green
Ready indicator starts flashing, a fault indication text is displayed on the HMI and an
event 0/E57 is generated. The fault indication
text on the HMI consists of two rows: a general message ‘internal fault’, followed by the
generated IRF code of the fault.
The relay will try to recover from a fault
either by restarting the module (I/O module
or HMI) that reported the fault, or by restarting the whole relay. During restarting the IRF
state will remain active until the internal selfsupervision program has determined that the
relay is operating normally. If the fault is still
persistent after restarting three times, the
relay will be in permanent IRF state.

1MRS750443-MBG
Feeder terminal configuration
Lon network configuration
The Relay Configuration Tool, based on the
IEC 61131-3 standard, is used for configuring
the basic terminal, protection and logic function blocks, control and measurement functions, timers and other functional elements
included in the logic functions category.
The LON Network Tool is used for binding
network variables between RED 500 terminals. Typically, LON is used for transferring
object status data (open, close, undefined)
between units for interlocking sequences running in the units.
The programmable system of REF 54_ feeder
terminals allows the output contacts to be
operated in accordance with the state of the
logic inputs and the outputs of the protection,
control, measurement and condition monitoring functions. The PLC functions (e.g. interlocking and alarm logic) are programmed
with Boolean functions, timers, counters,
comparators and flip-flops. The program is
written in a function block diagram language
by using the configuration software.
DNP 3.0 and Modbus configuration
Mimic configuration
The control functions configured using the
Relay Configuration Tool can be associated
with position indicators that are part of the
MIMIC configuration picture displayed on
the graphic LCD of the HMI. The MIMIC
configuration picture is designed with the
Relay Mimic Editor. In addition, the editor is
used to define the eight programmableLED
indicators and the corresponding alarm texts
on the front panel, the alarm modes, and the
interlocking LED texts.
The MIMIC picture may include a single-line
diagram, measured values with units, free
texts, etc. The position indicators (open,
closed, undefined) are drawn according to the
customer's requirements. Note that the operation of the objects themselves is determined
by means of the Relay Configuration Tool.
All of the eight alarm function blocks can be
configured in the same alarm view of the
mimic editor. ON and OFF state texts (only
one language version at a time can be supported for the alarm) and LED colours can be
defined. Three different colours can be used
to define the ON and OFF state. Three basic
modes are available:
• non-latched
• latched-steady
• latched flashing
Interlocking LED texts can also be defined in
the same alarm view but the colour of the
interlocking LED cannot be changed.
The Protocol Mapping Tool included in the
CAP 505 is used for configuring the DNP 3.0
and Modbus interfaces of the feeder terminal.
Feeder terminal
parameterization
The parameters of the feeder terminal units
can be set either locally over the HMI or
externally via the serial communication.
Local parameterization
When the parameters are set locally via the
HMI, the setting parameters can be chosen
from the hierarchical menu structure. The
desired language for parameter description
can be selected.
External parameterization
The Relay Setting Tool is used for parameterizing and setting the feeder terminals externally. The parameters can be set off-line on a
PC and downloaded to the feeder terminal
over a communication port. The menu structure of the setting tool, including views for
parameterization and settings, is the same as
the menu structure of the feeder terminal.
Terminal connections
All external circuits are connected to the terminal blocks on the rear panel. The terminal
block for the measuring transformers consists
of fixed screw terminals.
ABB sensors (Rogowski coil or voltage
divider) are connected to the feeder terminal
with special type of shielded twin BNC connectors. This type of connectors are used to
improve reliability and protection against disturbances. Unused sensor inputs must be
short-circuited with special connectors, type
1MRS 120515.
The RS232 serial interface on the rear panel
is used to connecting the feeder terminal to
the SPA, the IEC_103, Modbus, DNP 3.0,
Profibus, or IEC 61850 bus. The SPA,
IEC_103, Modbus and DNP 3.0 bus is connected through RER 123 Bus Connection
Module. DNP 3.0/Modbus can also be connected through the RER 133 Bus Connection
Module.

Terminal diagram of the RTD/analog module
Auxiliary voltage
For its operation, the REF 54_ terminal,
including the external display module,
requires a secured auxiliary voltage supply.
The feeder terminal’s internal power supply
module forms the voltages required by the
feeder terminal electronics. The power supply
module is a galvanically isolated (fly-back
type) dc/dc converter. A green protection
LED indicator on the front panel is lit when
the power supply module is in operation.
The feeder terminal is provided with a 48hour capacitor back-up protection that
enables the internal clock to keep time in case
of an auxiliary power failure.
Power supply
There are two basic types of power supply
modules available for the REF 54_: type
PS1/_ and type PS2/_. See Tecnical data table
9.The operating range of digital inputs
depends on the type of the power supply
module. See Technical data table 10.

General measurement/ analogue input on RTD/analogue module, MEAI1...8 (AI1...AI8)
The general measurement function blocks can be used to measure general purpose dc or ac voltage
signals with a sensor input. They also include a REAL type input which can be used to monitor any internal
REAL type IEC 61131-3 based signal, e.g. input data from the RTD/analogue module.

Analogue output on RTD/analogue module, MEAO1...4 (AO1...AO4)
The analogue output function blocks handle the scaling of any internal REAL type IEC 61131-3 based
signal to fit a selectable 0…20 mA or 4…20 mA range for use with the outputs on the RTD/analogue
module.
General REAL type input
-10000.00000...10000.00000
The recording can be triggered by any (or several) of the alternatives listed below:
• triggering on the rising or falling edge of any (or several) of the digital inputs
• triggering on overcurrent, overvoltage or undervoltage
• manual triggering via the menu or with the push-button F on the front panel (if configured)
• triggering via serial communication
• periodic triggering
The recording length depends on the number of recordings and inputs used. For example, the following
combination of recording length, number of recordings and number of inputs is available at 50 Hz:

Current waveform distortion measurement, PQCU3H, PQ 3inf (PQ 3inf)
The current waveform distortion measurement PQCU3H is used for measurement and statistical analysis
of current waveform distortion. The standards concerning voltage distortion measurement are applied to
current distortion measurement in PQCU3H. Data collection and analysis is done according to EN 50160.
Measuring principles for individual harmonics and THD are adapted from the International standard IEC
61000-4-7. The American standard IEEE Std 1159 is also partly supported. Analysis can be done for one
selected phase current or most distorted phase current can be tracked.

Short duration voltage variation measurement, PQVO3Sd, PQ3U< > (PQ3U< >)
The PQVO3Sd function block is used for measuring short duration voltage variations. Power quality is
being evaluated in the voltage waveform by measuring voltage swells, sags and interruptions. Power
quality measurements carried out by the function block PQVO3Sd follow the European Standard
EN 50160. Measuring principles are taken from the International standard IEC 61000-4-30.

Software configuration
Each REF 54_ feeder terminal allows various
software configurations based on separate
functions. Functions included in the selected
functionality level can be activated within the
scope of the I/O connections and considering
the total CPU load of the functions.

Parts and assembly
descriptions
To achieve the best possible operation accuracy, all parts of a REF 54_ product have
been calibrated together. Thus, each product
forms a whole for which no separate spare
parts can be supplied. In the event of malfunction, please consult your feeder terminal
supplier.
