Product introduction
UHV lightning impulse voltage generator is a core equipment in high-voltage electrical testing, specifically designed to simulate high amplitude, short rise time impulse voltage waveforms generated by natural lightning strikes in laboratory environments. It is mainly used to test the insulation performance and tolerance of power equipment (such as transformers, insulators, lightning arresters, cables, gas insulated switchgear, etc.) when subjected to lightning overvoltage.
