    GD-2133W Cable Sheath Fault Detector hits:

    General Information

    GD-2133W Cable Sheath Fault Detector is mainly used to pinpoint the sheath fault of single core cable, earth leakage fault of LV cable and prelocate sheath fault of HV cable. Also, it can be used to do withstand voltage test (10kV/1min) for XLPE cable sheath and find major risks of earth fault and leakage current in 10~500kV single core and three core HV and ultra HV cable sheath accurately. Besides, it can do DC hipot test (5~10kV/1min) for high density PE & PVC cable sheath.



    Test principle
    Sheath fault detection of underground cable is generally believed to have two steps: distance measurement and fault location, which is the same as that of power cable. There are two methods in distance measurement: voltage drop method and electric bridge method. For electric bridge method, it has the advantage of accurate measurement and simple operation, but it cannot measure multi point ground fault or test fault of three phase cable chain type ground connection. For voltage drop method, it can achieve both two measurements. Step voltage method is applied in pinpointing the cable sheath ground fault.



    Application

    • Coarse distance measurement of HV cable sheath fault after cable is laid.
    • HV cable sheath fault pinpointing after cable is being laid.
    • DC hipot test of ultra HV cable sheath.
    • Major insulation fault distance measurement of various voltage grades.
    • Cable fault location of buried cable 10kv and below.
