GE Multilin 760-P5-G5-HI-A20-R-E Integrated Line Protection Device

GE Multilin 760-P5-G5-HI-A20-R-E Line Integrated Protection Device (SR760 Feeder Management Relay)
I. Basic Description
Brand: GE Grid Solutions (formerly GE Multilin), not Woodward. It is often used in power stations in combination with the DCS system you previously queried from ABB Symphony and the parallel module from Woodward.
Full model: 760-P5-G5-HI-A20-R-E
The complete version of the standard full configuration model is 760-P5-G5-S5-HI-A20-R-E. Your model omits S5, indicating that it does not have a sensitive grounding CT input channel.

II. Complete Explanation of Model Segmentation 760 – P5 – G5 – HI – A20 – R – E
760: SR760 series feeder integrated protection and measurement control device, integrating protection, metering, recording, and communication
P5: Phase current CT secondary rated 5A (P1 = 1A)
G5: Zero-sequence grounding current CT secondary 5A; without S5 = without sensitive grounding circuit
HI: Wide voltage power supply (high-voltage power supply)
AC: 70~265VAC
DC: 88~300VDC, directly powered by the power supply cabinet of the power plant
A20: 8 channels full-range 4-20mA analog output, can be connected to ABB BIO01 / analog input card, DCS acquisition
R: Standard relay output configuration (standard trip, alarm, status contacts)
E: With Ethernet 10BaseT communication port, supports Modbus TCP, DNP3; without E only RS485 serial port

 Core Hardware Specifications
1. Current Input
Three-phase phase current: 5A CT
Zero-sequence grounding current: 5A CT
S5 sensitive grounding channel (compared to the model with S5, there is one less grounding collection channel)
2. Analog Output
8 independent 4–20mA, can upload current, voltage, power, fault signals to DCS system
3. Communication Interface
Standard RS485 (Modbus RTU)
Suffix E: Built-in Ethernet TCP/IP, dual communication redundant networking
4. Human-Machine Interface
Color LCD panel, operation keys, circuit breaker position LED indicator light, local event viewing
5. Mechanical and Environmental
Embedded cabinet-mounted plug-in chassis, can replace modules without power interruption
Operating temperature: -40℃ ~ +60℃
Protection IP20 (installed in the control cabinet)

Complete Protection Functions (High-voltage / Plant Power Feeder)
Phase-to-phase fault protection: time-limited / reverse-time overcurrent, short-circuit instantaneous trip
Grounding protection: zero-sequence overcurrent, grounding fault trip
Voltage protection: overvoltage, undervoltage, loss of voltage, frequency abnormality
Power protection: reverse power, overload, power factor monitoring
Automatic reclosing, circuit breaker failure protection, CT disconnection alarm
SOE event sequence recording, fault recording, electric energy metering (active / reactive / electricity consumption)
