Select the appropriate test method, and use the cable instrument host for rough testing of cable faults. Different methods should be used for different cable faults. Low-resistance faults (open circuit, short-circuit, etc.) should be tested by low-voltage pulse method; while high-resistance faults (leakage, flashover, etc.) etc.), you need to use the flash to select the appropriate test method, use the cable instrument host to perform a rough measurement of cable faults, and use different methods for different cable faults. Faults (leakage, flashover, etc.) are tested by the flashover method. After the method is selected, the approximate location of the cable fault is measured. Select an appropriate test method, and use the tracer host to perform a rough measurement of the fault distance of the cable.
Low-resistance faults are measured by low-voltage pulse method, and high-resistance faults are measured by high-voltage flashover method.
