Main Features and Advantages
Comprehensive Feeder Protection
The 760-P1-G1-S1-LO-A20-R provides protection and control functions for distribution feeders and can also provide backup protection for equipment such as transformers and transmission-line feeders.
1 A Current-Transformer Inputs
This order code uses 1 A phase, zero-sequence and sensitive-ground current inputs, making it suitable for installations using 1 A CT secondaries. The CT rating should be carefully matched when replacing an existing relay.
760-P1-G1-S1-LO-A20-R
Eight 4–20 mA Analog Outputs
The A20 option provides eight 4–20 mA analog outputs, allowing measured or calculated electrical parameters to be transmitted to PLC, DCS, SCADA or other monitoring equipment.
Low-Voltage Control Power
The LO configuration supports 20–60 VDC or 20–48 VAC at 48–62 Hz, making the relay appropriate for control cabinets with low-voltage auxiliary supplies.
Reclosing and Feeder Management
The 760 platform provides feeder management functions including automatic reclosing and protection logic. This can help restore feeder service after transient faults while maintaining protection against persistent faults.
Communication and Data Recording
The relay supports Modbus RTU and DNP 3.0, enabling integration with supervisory control systems. Event records and waveform capture assist with post-fault analysis, commissioning and maintenance.
Drawout Construction
The relay uses a drawout construction, allowing the electronic relay unit to be removed from its case for maintenance or replacement. Note that the SR760 case is normally separate from the relay unit.
Application Fields
Electrical Distribution
The primary application is medium- and low-voltage feeder protection. The relay monitors feeder current and provides protection and control functions for distribution circuits.
Industrial Plants
The relay is suitable for industrial power-distribution systems supplying motors, transformers, pumps, compressors and other process loads.
Power Generation
In generating facilities, the 760 can protect auxiliary distribution feeders and provide backup protection for transformers and related electrical equipment.
Oil & Gas and Petrochemical
Refineries and petrochemical plants can use the relay for feeder protection, breaker monitoring, fault recording and integration with plant SCADA systems.
Infrastructure and Utilities
Water-treatment plants, transportation infrastructure and utility distribution systems can use the 760 for feeder monitoring and automated protection.
Retrofit and Maintenance
The 760-P1-G1-S1-LO-A20-R is especially useful when maintaining existing GE Multilin 760 installations. The complete order code is important because the 760 family contains numerous variants with different CT ratings, power supplies, analog outputs and communication/display options. GE Multilin product listings continue to identify this exact configuration as part of the 750/760 feeder relay family.
