Industrial Sites—Apply GFD Ground Fault Detectors over cable at ground potential in live-front switchgear to identify faults on circuits feeding mining equipment, medical facilities, and other industrial equipment. The vinyl-coated sensor core and potted circuit components provide an excellent seal against moisture and humidity in challenging industrial environments. The split-core sensor installs on three-phase cables without the need to open the primary or interrupt vital industrial operations.
Underground Cable at Substations—Apply the GFD to an underground cable distribution circuit feeder before the feeder leaves the substation to identify ground faults in the underground section of the circuit.
Low Load Current—Choose a secondary reset option to power and reset the GFD from secondary voltage (120–240 VacL-N) at a transformer. The GFD reset and powering options provide a wide range of compatibility across various applications, especially where feeders are lightly loaded or there is no load present.
