What are the detection methods for cable faults? Reason for fault: 1. The insulation resistance has decreased. The breakdown of the cable core or insulation dampness reduces the insulation resistance value of the cable. 2. The DC withstand voltage test voltage is low and cannot meet the rated requirements. 3. During the AC withstand voltage test, excessive leakage current, waveform distortion, etc. caused disqualification. 4. When testing in the case of a short circuit, the measurement results are low due to the inductance effect; 5. Excessive environmental temperature can cause the temperature of the cable to rise and cause aging; 6. Cables laid indoors or in pipelines are subjected to long-term exposure to sunlight or other heat sources, resulting in degraded performance
Function of testing report:
