2. Description
• The 7SR157 Argus is a combined check and system synchronising relay which can carry
out controlled closing of a circuit breaker using measurements of the line and bus
voltages.
• The relay will prevent closure of the circuit breaker if the differences in phase angle,
slip frequency or magnitude of the voltages fall outside prescribed limits. If the
parameters are within limits, the relay will issue an output which can be used to close
the circuit breaker directly or in conjunction with an auto-reclose scheme.
• Housed in a 4U high, size E4 or E6 (Optional IEC61850 model) case, the relay provides
instrumentation and fault data with integrated input and output logic, data logging &
fault reports.
• Communication access to the relay functionality is via a front USB port for local PC
connection or rear electrical RS485 port for remote connection & optional IEC61850
communication through two rear Ethernet ports (Electrical or Optical)..
3. Function Overview
• Independent check, system synchronising and close on zero
settings.
• Adjustable slip frequency, phase angle, voltage blocking and
Differential voltage blocking.
• Split system detection.
• Configurable dead/live bus and dead/live line voltage settings,
(2 State and 3 State).
• Synchronising bypass logic is provided to connect a dead line
or bus to a live line or bus.
• For manual synchronising the relay includes a circuit breaker
close guard feature, which is used to prevent the control
switch being held closed during a synchronising operation.
Features:
• Four Settings Groups
• Password Protection – 2 levels
• User Programmable Logic
• Self Monitoring
4. Data Storage and Communication
• Standard Communications Ports
Communication access to relay functionality is via a front USB port for local PC connection
or rear electrical RS485 port for remote connection
• Additional Optional Communication Ports
2x Electrical RJ45 Ethernet ports
2x LC Fibre Optic Ethernet ports
• Standard Protocols
IEC60870-5-103, Modbus RTU, DNP3.0. User selectable with programmable data points
• Optional Protocols
IEC61850 (E6 Case)
• Ethernet Redundancy Protocols:
Standard in all IEC61850 models:
PRP (Parallel Redundancy Protocol)
RSTP (Rapid Spanning Tree Protocol)
HSR (High-availability Seamless Redundancy)
5. Application
• Check or system synchronising is required whenever two parts of a power system
network, each containing generation, have to be connected or re-connected
together.To avoid shock loading and possible damage to primary electrical plant the
voltage, frequency and phase angle difference between the two systems should be
within acceptable limits relative to one another.
• Where two systems have been previously interconnected, the frequencies of the
two systems will drift apart slowly following circuit breaker tripping and the phase
angle difference will increase. Here the slip rate will be small and the circuit breaker
can be closed using check synchronising settings as the limiting parameters.
• However, if the two systems become asynchronous so one system is an ‘island’ of
generation then a high rate of slip may result causing the two systems to pass
through anti-phase conditions.The relay will detect this system split condition,
inhibit the check synchronising algorithms and apply system synchronising settings
as limiting parameters.Typically in this mode the slip rate will be much higher and
so there will be a narrower allowable phase angle difference before closing. In
addition, closure of the circuit breaker will only be allowed under conditions of
decreasing difference in phase angle.
6. Functional Diagram
Ethernet Communications
• IEC61850 communication is available through an optional EN100 communication module.
The EN100 Module can be ordered with either 2x Electrical RJ45 or 2x Fibre optic LC
Ethernet ports.
• Information on IEC61850 functionality can be found in the following 7SR157 documents:
Model Implementation Conformance Statement (MICS)
Protocol Implementation Conformance Statement (PICS)
Protocol Implementation Extra Information forTesting (PIXIT)
7. Serial Communications
• The relay offers a USB serial port as standard on the front of all units.All of the relays
functions can be set on a PC using Reydisp Evolution via the USB port.The connection is
made with a USB cable and operates with a ‘plug and play’ connection, so no pre-setting of
the relay is required.The front port can be switched off or set to use either the DNP3.0,
MODBUS-RTU, IEC60870-5-103 or ASCII protocols for testing purposes.
• A rear RS485 electrical connection is available on all units for system interface connections.
An internal terminating resistor is provided, which can be connected into the circuit by
adding a wire loop between the relevant terminals.
The rear RS485 can be user selected to be OFF, IEC60870-5- 103, MODBUS RTU or DNP3.0
protocol.
8. Data Acquisition -Via Communication Interface
Sequence of event records
Up to 1000 events are stored and time tagged to 1ms resolution.
Fault Records
The last 10 fault records are displayed on the relay fascia and are also available through the
communication interface, with time and date of trip, measured quantities and type of fault.
Waveform recorder
The waveform recorder stores analogue data for all poles and the states of protection
functions, binary inputs, LEDs and binary outputs with user settable pre & post trigger data.
Demand Metering
The Demand Metering Calculates the maximum, minimum and mean values of Line and Bus
voltages and displays it as instruments which can be read in the relay INSTRUMENTS MENU
or via Reydisp.
RealTime Clock
The time and date can be set and are maintained while the relay is de-energised by a back up
storage capacitor.The time can be synchronized from a binary input pulse or the data
communication channel.
9. User Interface

menus, entering settings and retrieving data from the relay. Five buttons are provided for
navigation around the menu structure.
LCD
A 4 line by 20 character liquid crystal display
with power save operation indicates the relay
identifier, settings, instrumentation, fault data and
