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 32 kV to find out which phase is faulty and determine its breakdown voltage and the leakage current.
Inbuilt Burn down facilityIn 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 240 mA is provided on 8kV range.
ThumperIt produces high voltage surges up to 32 kV with 1000 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.
