Description
Product Overview
The GE 760-P5-G5-S5-HI-A20-R-E is a digital multifunction feeder protection relay from the GE 760 series. It acts as an integrated protection and monitoring device for medium-voltage distribution feeders in power plants and utility substations. This relay combines multi-segment fault protection, high-precision electrical measurement, event logging and local human-machine interface. It continuously tracks feeder operating conditions and executes rapid tripping actions once electrical faults are detected.
Medium voltage feeders face constant hazards such as short-circuit, overload and earth faults. These faults can destroy power assets and trigger widespread power outages. Many generic protective relays cannot match the original protection curves and communication register mapping. They introduce hidden risks for feeder protection loops after replacement. To resolve these safety risks, the GE 760-P5-G5-S5-HI-A20-R-E adopts mature digital signal processing architecture. Every unit passes protection logic verification, sampling calibration and full-load aging testing before shipment. It serves as original spare equipment for substation renovation and feeder protection upgrade, and fully supports global industrial e-commerce procurement.
