GE's generator protection devices provide 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.
Multilin G60The G60, a member of the UR family of protection relays, provides ultimate protection for AC generators. Provides 100% stator ground fault by low frequency injection (GPM-S module required) and field ground fault protection (GPM-F module required). It offers a large color LCD display, integrated PMU and process bus and is on the US Government GSA schedule.
MiCOM P34x Agile
The P34x models, members of the MiCOM P40 Agile family of protection relays, offer cost effective protection for AC generators. They can provide 100% stator ground fault by low frequency injection (P345, GPM-S module required) and field ground fault protection (P391 module required).
Multilin 889 The 889, a member of the 8 series family of protection relays, has been designed for industrial customers and small to medium utility generators. It offers a large color LCD display and Wi-Fi connectivity to configure settings and retrieve records.
Multilin GPM-S The GPM-S is a Stator Ground Protection Module that provide 100% stator ground fault protection during generator start-up, running and stopped conditions. It is based on sub-harmonic injection of a 20Hz voltage to continuously monitor the integrity of the stator windings. The GPM-S can be used with either of the Multilin G60 or the MiCOM Agile P345 relays.
Multilin GPM-F The GPM-F is a Ground Protection Module for monitoring the generator field/rotor windings. Working in combination with the Multilin G60 relay, the GPM-F provides detection of ground faults in the field winding of the generator. The device can be used for either single point or double point injection based on application requirements.
Multilin G30Protection of small to medium sized generators, including unit transformer protection, part of the UR family of protection relays. It offers a large color LCD display, integrated PMU and process bus.
