Pipeline grounding fault diagnosis (optional function) :The traditional high-voltage flashover method can accurately locate ground insulation faults in buried power cables, buried communication cables, buried optical cables, etc. When applied to ground faults in buried cables, the discharge energy of the single-phase metallic ground fault point is directly proportional to the square of the discharge current and the ground resistance. Therefore, the sound of the fault clicking through the gap discharge is light and cannot be accurately located, and even in most outdoor noisy situations, the sound wave cannot be accurately captured, resulting in the inability to locate. Based on path detection instruments and A-frames for cable ground fault positioning, the step voltage method is used for measurement, and the results are stable, simple and easy to use, with accurate positioning. It can be used for accurate fault detection of ground faults in buried cables in multiple scenarios. Arrow direction indication.
