Knowledge sharing: Methods for determining the nature of power cable faults

2025-07-28

Latest company news about Knowledge sharing: Methods for determining the nature of power cable faults

There are generally three ways to judge the nature of cable faults:

(1) Judge by insulation resistance meter or multimeter;

(2) Judge by cable pre-test results;

(3) Judge by "cable fault tester";

Generally, low resistance and open circuit faults (high resistance) can be directly judged by the "low voltage pulse method" test waveform of a multimeter or "cable fault tester".
