GE GPM-S Complete Generator System Protection

GE GPM-S Complete Generator System Protection

Stator ground module works in combination with GE’s Multilin 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

Applications

Medium to large sized generators

Generators with high impedance grounding

Deployable with redundant generator protection systems

Suitable for unit transformer connected systems
