Typical Leakage Current Cable Testing at Randall Maupin blog

Typical Leakage Current Cable Testing. Any increase of leakage current. When at some local point in a cable, insulation has deteriorated to a degree that a breakdown occurs allowing a surge of current to ground, the cable is referred to as a faulted. Or no breakdown occurs, i.e., there is no sudden and uncontrolled flow of current. The dc hipot is a good choice for pilc cables because pilc cables commonly fail by conduction which can be measured by a test. With good insulation, the conduction or leakage current should build up to a steady value that is constant for the applied voltage, as shown in fig. The total current flow, when a dc voltage is applied, starts at a relatively high value and then drops, settling at a value just slightly above the leakage current. Leakage current is the sum of all ac currents from mains conductors to ground through these resistances and impedances: The leakage current measured is less than the maximum allowable current;
