Product Description

HV HIPOT power frequency impulse voltage test impulse voltage generator

 

General information

The impulse voltage generator is a device that generates impulse voltage waves. It is used to check the insulation performance of power equipment withstand atmospheric overvoltage and operating overvoltage. The impulse voltage generator can generate standard lightning impulse voltage waveforms, lightning impulse voltage cutoff, standard operation impulse voltage waveforms, etc. and user-specified non-standard impulse voltage waves (including steep waves).
GDCY series impulse voltage generator can carry out impulse voltage test and other scientific research on insulators, long air gaps, bushings, CT/PT, transformers and other samples.
