earth-leakage protection relay / panel-mount
Stator ground module combines with UR G60 to work for ensuring 100% stator ground fault protection that is operational during generator start-up, running and stopped conditions. 100% stator ground fault protection is esnured by sub-harmonic injection. The ground faults at any point across 100% of the winding is detected through injection of 20Hz voltage to completely protect the stator winding. The stator ground faults are also detected earlier.
