What is the correct way to open the cable fault tester, then we need to understand some common problems of cable faults, and then effectively solve the fault problems according to different problems. With the development of my country's power system, the laying of high-voltage cables has become more and more common. Basically, the cables connected between substations and stations are very long. As long as the cables are faulty, it is very difficult to troubleshoot, and most of them are buried in the ground. Cables are difficult to judge by human beings. At this time, a cable fault tester is needed to judge the correct fault point for us so that we can quickly restore the power supply. Then we analyze the problem according to several common cable faults. Cable faults are commonly divided into high-resistance short-circuit faults, phase-to-phase short-circuit faults, low-resistance faults, and flashover faults.
