Fault Locator
Key words:
The cable fault location device uses the principles of vibration sound pickup and electromagnetic induction to accurately locate the cable fault point. The high-voltage pulse generator triggers flashover discharge at the fault point, and the generated vibration waves, sound waves and electromagnetic waves are picked up by a special probe, amplified and processed by the instrument, and output through audio-visual signals, ultimately achieving accurate positioning of the fault point within the rough measurement range directly above the cable. The device is suitable for power cables, high-frequency coaxial cables, street light cables and underground wires of different cross-sections and media. It can detect low-resistance, short-circuit, open-circuit and broken wire faults, as well as high-resistance leakage and high-resistance flashover faults. The technical parameters meet the "DL∕T 849.2 General Technical Conditions for Special Testers for Power Equipment Part 2: Cable Fault Location Device" standard.
