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. Generator protection is critical to maintaining maximum uptime in the generating facility and providing vital protection of the generating unit.
