Product Overview
Overview:
The 600 kV/30 kJ Lightning Impulse Generator is a high-voltage testing system that simulates the effects of lightning strikes on electrical equipment by generating extremely short-duration, high-power electrical pulses. This device is used to verify whether high-voltage components such as transformers, insulators, and surge arresters can withstand these transient overvoltages without failure.
