WebGround relays for these systems require high relay sensitivity because the fault current is very low compared to solidly grounded systems. Most ground-fault detection methods use fundamental-frequency voltage and current components. The varmetric method [2] is the traditional ground fault detection solution in ungrounded systems. WebBy continuously monitoring the system's insulation resistance, Bender's ground-fault detectors can provide early indication of both immediate and trending ground faults before leakage current may be of concern. Bender's advanced insulation monitoring technology detects symmetrical and asymmetrical faults on both AC and DC systems, as well as ...
