The field of applications is mainly the industrial test facility, university lab and country HV research centers. The system can be used to generate impulse voltages simulating lightning strokes.This Impulse voltage generator suitable for lightning impulse full wave, chopping wave, inspect equipment’s impulse insulation level. The system can also be used for POWER CABLE’s impulse flashover test and POWER CABLE impulse characteristic research under nonuniform pollution.
The impulse voltage generator is the main part of an impulse voltage test system such as  HIVG1200kV120kJ Impulse Voltage Generator Test System.
