Application: 
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 and switching surges. This Impulse voltage generator suitable for lightning impulse full wave, chopping wave, switching impulse test, inspect equipment’s impulse insulation level. The system can also be used for insulator’s impulse flashover test and insulator impulse characteristic research under nonuniform pollution.
The impulse voltage generator is the main part of an impulse voltage test system such as HIVG2400kV240kJ Impulse Voltage Generator Test System.
