General information
Impulse Voltage Test System is mainly used to generate lightning impulse voltage, to research and check the ability of lightning impulse ability of electric equipment. It can generate standard lightning waveform and chopping waveform.
The system can be used for impulse voltage test and other scientific research on GIS, cable, insulators, air gap, bushing, transformers etc.
