11 kV Underground Cable Fault Locator

It is used to produce high voltage surges, perform DC high voltage testing and provide burning facility
Inbuilt Pressure Testing (Hi-pot Test):-
Perform DC high voltage testing up to 16 kV to find out which phase is faulty and determine its breakdown voltage and the leakage current
Inbuilt Burn down facility:-
In case of high resistive faults, burning is required. Burning will reduce the breakdown voltage of the fault and it will be easy to pre-locate and pinpoint. Hence, burning facility of at least 575 mA is provided
Thumper:-
It produces high voltage surges up to 16 kV with 2000 Joules energy. With Reflectometer the high voltage surge produced by the Surge Generator are used to find the distance to the underground cable fault. These high voltage surges will create an electromagnetic signal along the cable and a flash over will occur at the fault point leading an acoustic signal, Digipoint will identify these signals and indicate the route of the cable to pinpoint the exact location of the fault
ARC Reflection Filter:-
High resistive cable faults and intermittent faults can easily be located with the ARM Method - if the cable fault resistance is too high for direct measurement with pulse echo method, a surge generator provides a low resistance arc at the fault, which is then clearly located by the Reflectometer like a low resistance fault via an ARC Reflection Filter. The Reflectometer shows a comparison of the traces with and without the arc - it is an easy, clear and precise method and therefore the most commonly used cable fault locating procedure today
