Alstom / GE 489 Generator Protection System

GE’s 489 Generator Protection System provides innovative solutions for the protection, control and monitoring of generator assets. Generator protection is critical to maintaining maximum uptime in the generating facility and providing vital protection of the generating unit. From the protection and control of utility generators to ensuring safe interconnection of renewable energy sources, to synchronization and load shedding solutions using advanced automation, GE maximizes asset reliability and operational life.

The SR489 Generator Protection System, a member of the SR family of relays, provides protection, control and advanced communications in a cost effective industry leading draw-out construction. Designed for small and medium sized generators, the 489 delivers advanced protection including generator stator differential protection. The 489 also includes detailed diagnostic information allowing for reduced troubleshooting time.
