This system consists of two parts: cable fault prelocotor and high-voltage pulse generator. It is used to test the main insulation fault of medium and low voltage power cables of 35kV and below and calibrate the cable length.
Cable fault prelocotor----adopts a simple system operation interface, touch operation mode, built-in large-capacity lithium-ion battery, stable and reliable, easy to use. It has an independent charging power supply and power supply system to prevent power supply interference during impact discharge.
High-voltage pulse generator----powered by AC220V, including DC withstand voltage, single pulse, and periodic pulse output functions, including a signal feedback device, which is convenient for cable fault tester sampling; and is equipped with zero protection, shutdown automatic discharge and other functions.
This cable fault testing system is suitable for low-resistance, short-circuit, open-circuit and broken wire faults of power cables, high-frequency coaxial cables, street light cables, and underground wires of various materials with different cross-sections and different media, as well as high-resistance leakage and high-resistance flashover faults.
