Overview
The GE Multilin G30 Generator Protection System Relay provides comprehensive protection for steam, hydraulic, and combustion-turbine generators. It is especially effective when the generator and transformer share a common protection zone, offering coordinated differential and ancillary protective functions.
Built on GE’s proven Universal Relay (UR) platform, the G30 delivers advanced automation, flexible I/O configuration, and powerful disturbance recording capabilities. These features support fast troubleshooting, improved system visibility, and reduced downtime.
The configuration G30-V03-HKH-F8L-H6D-M8L-P6X-U6T-WXX represents a custom-assembled hardware and firmware option set, including communication interfaces, I/O banks, and specialized protection modules tailored for demanding industrial and utility environments.
