Overview

The GE Multilin 760-P5-G5-D5-HI-AI-R is part of the 750/760 series of digital feeder protection relays developed by GE Vernova. This relay is engineered to provide comprehensive protection, control, and monitoring for medium-voltage distribution feeders. It supports high-speed fault detection, breaker control, and backup protection for transformers, buses, and transmission lines.

Moreover, the 760 relay features a draw-out construction for simplified maintenance and replacement. It includes built-in metering, waveform capture, event logging, and IRIG-B time synchronization, which help reduce troubleshooting time and improve system reliability. Therefore, it is widely used in substations, industrial plants, and utility networks where uptime and fault resilience are critical.

For instance, in a manufacturing facility, the 760 relay can isolate feeder faults within milliseconds, protecting equipment and maintaining operational continuity.

Technical Data

Typical Applications

• Distribution Feeder Protection – Provides primary protection and control for medium-voltage feeders in substations and industrial plants.
