The trolley-type cable fault locating system highly integrates traditional and independent cable fault testers, integrated high-frequency and high-voltage power supplies, multiple pulse generators, path transmitters, insulation resistance testers, and other independent units. The system is used for rough testing of various fault distances, path finding, and precise fault location of power cables. The testing software automatically recognizes the card position and reads the fault distance, truly making the testing of cable faults light, simple, efficient, and safe. Provide convenience for rapid testing of power cable faults.
