Alstom / GE GPM-S Stator Ground Protection Module

GPM-S Stator Ground Protection, Stator ground module works in combination with GEs Multlin G60 and MiCOM Agile P345 to provide a 100% stator ground fault protection that is operational during generator start-up, running and stopped conditions. In the 100% stator ground fault protection based on sub-harmonic injection, a 20Hz voltage is injected to detect ground faults at any point across 100% of the winding thereby protecting the complete stator winding and allowing early detection of stator ground fault conditions.

Key Benefits
? Detect ground faults through 100% of the stator winding including neutral point
? Sub-harmonic injection based stator ground protection provides early detection of ground fault conditions
? Designed to operate with industry leading G60 and P345 Generator Protection Systems
? Active protection of the generator even under machine shutdown conditions for increased asset life
? Providing a wide range of fault resistance coverage which allows for greater generator protection
? Increase generator life span by easily upgrading your current G60 or P345 generator protection relay with the 100% Stator Ground Protection Module

GE’s generator protection devices provide innovative solutions for the protection, control and monitoring of generator assets.
