Xzh Test Underground Cable Fault Locator Set 0-35kv Tdr Cable Fault Location System

XZH TEST Underground cable fault locator set 0-35KV TDR cable fault location system can a ccurately and quickly detect the main insulation failure of power cables with voltage levels of 35KV and below; calibrate the cable length; accurately detect the direction and depth of the cable buried.



The system include a TDR cable fault pre locator, a high voltage surge generator and a cable fault pinpointer.
Model number: XHGG501A, XHHV535-2L, XHDD503B

The system can quickly detect low-resistance, short-circuit, open-circuit and disconnection faults of various types of power cables with different cross-sections and different media, high-frequency coaxial cables, local telephone cables, street lamp cables, and buried wires, as well as high-resistance leakage and high-resistance flashover For permanent main insulation faults and outer sheath faults, calibrate the cable length.

1) TDR Cable fault pre locator XHGG501A: With computer control, color display touch operation mode, strong anti-interference ability ;
2 ) System functions: fault distance measurement, fault pinpoint location, propagation speed test.
3)System test methods: low-voltage pulse,Impulse Current Method (ICE-Method = Impulse
Current Equipment), audio method, ARM - Arc Reflection Method (HV-supported reflection
method), acoustic-magnetic synchronization method, electromagnetic induction method, etc.;
4 )TDR T est distance: ≤60 km
5 ) Measurement accuracy: Rough measurement error: ±10m (absolute value) or 1% (relative value), fine measurement error: ±0.2m (fixed point, path, depth); 
6 )TDR  Sampling frequency: 400MHz, minimum resolution 0.5m (100m/us)
7 )TDR  Sampling method: automatic continuous sampling, never miss any discharge waveform.
8 ) Low voltage pulse: Width: Adaptive Amplitude: 400Vpp
