Impulse Voltage Generator

Impulse voltage generator can be used to generate impulse voltages simulating lightning impulse (1.2±30%/50±20%μs), chopped lightning impulse (chopped time between 2~6μs to test power transformers, instrument /voltage transformers and bushings), switching impulse (250±10%/2500±10% μs) and steep front waveforms (to test glass insulator, composite insulators or ceramic insulators) .
