    GD-2137H Cable Fault Test System hits:

    Main parts:

    • GD-2133M Cable fault tester (hereinafter referred to ad host machine)
    • GD-2132T Cable path detector (hereinafter referred as to signal generator)
    • GD-2131H Integrated DC HV generator



    Fault distance measurement:

    • LV impulse method: to measure distance of low impedance fault (LIF), short circuit and line breakage accurately.
    • Impulse current method: to measure distance of high impedance fault (HIF) and flash-over. Signals are collected from ground cable via current coupler, which is separated from HV part, safe and reliable.

    GD-2131H Integrated DC HV Generator

    GD-2131H Integrated DC HV Generator serves as the auxiliary HV source when surge flash-over method is used to detect HV impedance fault.

     

    Features

    • Strong burn-out ability, Max. burn-out power is 1000W. Breakdown point is burnt out in short time to reduce resistance.
    • Combined with GD-2133M cable fault comprehensive tester, it will have location method as below: LV impulse method: GD-2133M alone can locate ground faults of open circuit and low impedance, measure cable length and check wave speed on the cable; HV flash-over method: impulse voltage waveform at faulty point discharge is sampled via spark gap to locate faulty point distance.
    • Impulse of a fixed frequency is generated, combined with GD-2132T signal generator for cable route tracing, it has function as below: Audio method is used to pinpoint general high impedance and flash-over point; Trace the route of cable and identify a certain cable; It can also be used in DC hipot test.
