Ground Fault Current Detection Systems
Model GFL ( S e n s o r )
Trip Currents 5 - 60 , 3 0 - 360 , or 10 0 -1 2 0 0 A
Ground Fault Current Sensors, type GFL, are available in three different styles, a variety of sizes and current ranges - to
match the BGFL relay ranges. The physical size of the sensor window should be carefully determined by the physical size and
conf iguration of the power conductors. The Ground Fault Sensor will respond only to ground faults which occur between the
position of the sensor and the load. Each sensor has two sets of windings one for test and one for normal operation.
