— Measuring inputs with traditional CTs and VTs
— Measures
• Three phase current inputs and one residual current input,
with nominal currents independently selectable at 1 A or 5 A
through DIP-switches.
• Three phase voltage inputs with programmable nominal voltages within range 50...130 V (UR =100 V) or 200...520 V (UR =400 V)
and one residual voltage input, with programmable nominal
voltage within range 50...130 V (UER =100 V).
NA60 provides metering values for phase and residual currents,
phase and residual voltage, making them available for reading
on a display or to communication interfaces.
The input signals can be acquired through the traditional CTs
and VTs, or through combined sensors ThySensor including current, voltage measures, standardized lamp voltage presence
and isolated in the same component.
For residual current measurement (protection 50N/51N and 67N)
the installation of a balance current transformer is required,
while the residual voltage is derived through vector calculus on
the three phase voltages using the sensors ThySensor, or is selectable from the above calculation and the broken Delta VT in
versions with traditional VT inputs.
Input signals are sampled 24 times per period and the RMS value
of the fundamental component is measured using the DFT (Discrete Fourier Transform) algorithm and digital filtering.
With DFT the RMS value of 2nd, 3rd, 4th and 5th harmonic of
phase current are also measured.
On the basis of the direct measurements, several calculated
(min, max, average,...), phase, sequence, power, harmonic, demand and energy measures are processed.
Measures can be displayed with reference to nominal values or
directly expressed in amperes and volts.
— Measuring inputs with ThySensor devices
• Three phase current inputs, with 630 A nominal current (primary).
• One residual current input, with nominal currents independently selectable at 1 A or 5 A through DIP-switches.
• Three phase voltage inputs with nominal voltage 20/√3 kV (primary); the residual voltage has been obtained by vector calculation measures of phase voltages
— Firmware updating
The use of flash memory units allows on-site firmware updating.
— Construction
According to the hardware configurations, the NA60 protection relay can be shipped in various case styles suitable for the
required mounting options (flush, projecting mounting, rack or
with separate operator panel) and with connections to input signals suitable for traditional VTs and CTs ( screw terminals) or
combined sensors ThySensor (RJ45 connectors for connecting
embedded cables)
— Blocking input/outputs
One output blocking circuit and one input blocking circuit are
provided.
The output blocking circuits of one or several Pro_N relays,
shunted together, must be connected to the input blocking circuit of the protection relay, which is installed upstream in the
electric plant. The output circuit works as a simple contact,
whose condition is detected by the input circuit of the upstream
protection relay.
Use of suitable pilot wire to fiber optic converters (BFO) allows
to perform fast and reliable accelerated logic selectivity on radial and closed ring networks.
— Modular design
In order to extend I/O capability, the NA60 hardware can be customized through external auxiliary modules:
• MRI - Output relays and LEDs
• MID16 - Binary inputs
• MCI - 4...20 mA converter
• MPT - Pt100 probe inputs.
— Output relays
Six output relays are available (two changeover, three make and
one break contacts); each relay may be individually programmed
as normal state (normally energized, de-energized or pulse) and
reset mode (manual or automatic).
A programmable timer is provided for each relay (minimum
pulse width). The user may program the function of each relay
according to a matrix (tripping matrix) structure.
— Communication
— Binary inputs
Two binary inputs are available with programmable active state
(active-ON/active-OFF) and programmable timer (active to OFF/
ON or ON/OFF transitions).
Several presettable functions can be associated to each input.
Multiple communication interfaces are implemented:
• One RS232 local communication front-end interface for communication with ThySetter setup software.
• Two back-end interfaces for communication with remote monitoring and control systems by:
- RS485 port using ModBus® RTU, IEC 60870-5-103 or DNP3
protocol.
- Ethernet port (RJ45 or optical fiber) using ModBus/TCP protocol.

— MMI (Man Machine Interface)
The user interface comprises a membrane keyboard, a backlight
LCD alphanumeric display and eight LEDs.
The green ON LED indicates auxiliary power supply and self diagnostics, two LEDs are dedicated to the Start and Trip (yellow
for Start, red for Trip) and five red LEDs are user assignable.
as a warning for a possible short circuit in the pilot wire or in the
output circuit of the downstream protection.
The logic selectivity function can be realized through any combination of binary inputs, output relays and/or committed pilot
wires circuits.
— Self diagnostics
All hardware and software functions are repeatedly checked
and any anomalies reported via display messages, communication interfaces, LEDs and output relays. Anomalies may refer to:
• Hw faults (auxiliary power supply, output relay coil interruptions, MMI board...).
• Sw faults (boot and run time tests for data base, EEPROM
memory checksum failure, data BUS,...).
• Pilot wire faults (break or short in the wire).
• Circuit breaker faults.
— Event storage
— Control and monitoring
Several predefined functions are implemented:
• Activation of two set point profiles
• Phase CTs and VTs monitoring (74CT and 74VT)
• Logic selectivity
• Cold load pickup (CLP) with block or setting change
• Trip circuit supervision (74TCS)
• Second harmonic restraint (inrush)
• Remote tripping
• Circuit Breaker commands and diagnostic
User defined logic may be customized according to IEC 61131-3
standard protocol (PLC).
Circuit Breaker commands and diagnostic
Several diagnostic, monitoring and control functions are provided:
• Health thresholds can be set; when the accumulated duty
(ΣI or ΣI2t), the number of operations or the opening time exceeds the threshold an alarm is activated.
• Breaker failure (BF); breaker status is monitored by means
52a-52b and/or through line current measurements.
• Trip Circuit Supervision (74TCS).
• Breaker control; opening and closing commands can be carried out locally or remotely.
Cold Load Pickup (CLP)
The Cold Load Pickup feature can operate in two following
modes:
• Each protective element can be blocked for a adjustable time.
• Each threshold can be increased for a programmable time.
It is triggered by the circuit breaker closing.
Several useful data are stored for diagnostic purpose; the events
are stored into a non volatile memory.
They are graded from the newest to the older after the “Events
reading”command (ThySetter) is issued:
• Sequence of Event Recorder (SER).
The event recorder runs continuously capturing in circular
mode the last three hundred events upon trigger of binary input/output.
• Sequence of Fault Recorder (SFR).
The fault recorder runs continuously capturing in circular
mode the last twenty faults upon trigger of binary input/output
and/or element pickup (start-trip).
• Settings recording
Following some setting changes the last eight changes are recorded in circular mode (Data Logger CEI 0-16)
• Trip counters.
— Digital Fault Recorder (Oscillography) [1]
Upon trigger of tripping/starting of each function or external signals, the relay records in COMTRADE format:
• Oscillography with instantaneous values for transient analysis.
• RMS values for long time periods analysis.
• Logic states (binary inputs and output relays).
Note - A license for Digital Fault Recorder function is required, for purchase
procedure please contact Thytronic.
The records are stored in nonvolatile memory
— Programming and settings
All relay programming and adjustment operations may be performed through MMI (Keyboard and display) or using a Personal
Computer with the aid of the ThySetter software.
The same PC setup software is required to set, monitor and configure all Pro_N devices.
Two session level (User or Administrator) with password for sensible data access are provided.
ThySetter
Second harmonic restraint
To prevent unwanted tripping of the protective functions on
transformer inrush current, the protective elements can be
blocked when the ratio between the second harmonic current
and the relative fundamental current is larger than a user programmable threshold.
The function can be programmed to switch an output relay so
as to cause a blocking protection relays lacking in second harmonic restraint.
Logic selectivity
With the aim of providing a fast selective protection system
some protective functions may be blocked (pilot wire accelerated logic). To guarantee maximum fail-safety, the relay performs a
run time monitoring for pilot wire continuity and pilot wire shorting. Exactly the output blocking circuit periodically produces a
pulse, having a small enough width in order to be ignored as an
effective blocking signal by the input blocking circuit of the upwards protection, but suitable to prove the continuity of the pilot
wire. Furthermore a permanent activation (or better, with a duration longer than a preset time) of the blocking signal is identified,
