Cable Fault Finder

Cable Fault Finder
Cable Fault Finder

To test the HV arcing fault of cable, earthing high &low resistance, short circuit and breakage of the cable, poor contact, etc. If equipped with cable fault finder / locator, it can decide the exact broken position of the cable ,applies to power cable in various type, voltage and communication cable  

Cable fault finder Features

  1. Multi functional, safe, fast speed and accurate. It uses LV impulse method and HV flashover method to test, can test kinds of fault of the cable, if equipped with sound locator, can accurately the position of the fault point

  2. High precision, adopts high-speed sampling technique, A/D sampling speed is 100MHz, resolution is 1m, detection blind area is 1m.

  3. High degree of intelligence, test results auto displayed by LCD.

  4. Can store and review the waveform and parameters, these information will not loss after power off.

  5. Dual display, compare the measured waveform and normal waveform of the fault cable, benefit to further detection of the fault.

  6. With function of wave form expansion ratio, change the proportion of the waveform, expand the waveform to test.

  7. Directly display the direct distance or relative distance between fault point and measured point.

  8. Can modify the speed according different measured cable.

  9. Portable design , small in volume , with rechargeable battery, easy to carry and operate.  

Product Technical Parameter




This cable fault finder/ detector can test all types power

cable (voltage class 1kV~35kV) , local cable, FM

communication cable, coaxial cable, short

circuit, earth, high resistance leakage, high

resistance flashover fault of the metal overhead

lines, and the broken & poor contact of the

cable. It also can test the length of the cable and

the speed of the electric wave on the cable.
