Product Introduction

The lightning impulse generator is mainly used for conducting impulse voltage tests on power equipment and other test samples, including full wave lightning impulse voltage, truncated lightning impulse voltage, and operational impulse voltage waves, to test their insulation performance. As a power supply device that imitates lightning and operating overvoltage and other impulse voltages, it is widely used in insulation impulse withstand voltage and dielectric impulse breakdown, discharge and other tests. We provide complete sets of impulse voltage (current) test devices with various capacities, and can offer various waveform series of complete impulse voltage (current) generators.

The impact test device mainly consists of a generator body, a chopper, a voltage divider, a four component control console (divided into microcomputer and ordinary models), a digital waveform recording system, etc.
