High  Voltage  testing  equipments   are  necessary   for any  HV substation equipment  testing,  Panel Testing, Cable Testing, rated voltage  test, weak- point  in the insulation  quality  test. HV Breakdown   testing  or High-Voltage Proof  testing   is  one  of  the  most  commonly    used  methods   to  check insulation   levels  that  any  equipment   can  sustain,  without   a  flash-over taking   place.     Hi-pot  Test  equipments    ranging   from   100V  to  100kV, available  in power ratings ranging from 1OOVAto 100KVA.
