DC power system grounding is an abnormal occurrence which may lead to system damage. If the DC system is grounding when the positive electrode anode system is grounding, the power system protection relay device may falsely trip or switch off the DC power supply. When the negative electrode of the DC system is grounding, the DC system may short circuit and the switch closing function may not trigger which will cause a protection relay failure. This in turn may cause a relay or fuse to burn out and possible other failures.

This portable DC ground fault locator uses advanced computation methods and fuzzy logic to rapidly and accurately display the insulation level of a tested circuit branch providing an insulation index and waveform. It is specially designed for use in power generation, distribution, and industrial applications where lines have high capacitive reactance, electromagnetic, and electrostatic fields.
