Description
The GAI-Tronics GM8950 combined Ground Check Monitor / Ground Fault Relay (GFR) consists of a GM8900 Ground Check Monitor (Ground Sentinel®) and a GFR in a shared housing. They are intended to be used on the same three-phase AC mine electrical circuit. The trip contacts of the Ground Sentinel and GFR are internally pre-wired for series or shunt trip of the mine circuit breaker.
The GAI-Tronics Ground Sentinel along with the associated filters is designed to monitor the continuity of the ground circuit of electrical power circuits in mines. The three-phase wires or the pilot wire are used as a return signal path for the
Ground Sentinel.
