GPM-S Stator Ground Protection Module Continuous monitoring and protection for a generator's stator windings. The Multilin GPM-S Stator Ground Protection Module continuously monitors the integrity of the stator windings during stopped, starting and running conditions. This additional stator protection provides early detection of winding degradation, limiting potentially critical failures, costly asset damage, and costly system downtime.
GPM-F Field Ground Protection Module Continuous monitoring for generator field windings. Working in combination with the Multilin G60 Generator Protection System, the GPM-F provides detection of ground faults in the field winding of the generator. For application flexibility the device can be configured for either single point or double point injection to ensure maximum asset life.
