Product Description

300kv Impulse Voltage Generator Lightning Impulse Test Machine
 

I. Brief introduction

Multistage impulse generator is a test equipment to simulate the high voltage of pulse. In real life, pulse high voltage is often encountered. For example, in nature, lightning strikes, the lightning will appear very high pulse current and voltage, the surrounding will also sense a very high pulse voltage, and in the power system, the switching equipment in the joint operation will also lead to transient pulse voltage. These transient pulse voltage amplitudes are often in the tens of thousands of kV or more, which will cause equipment damage and endanger personal safety, so it is necessary to conduct test studies on shock voltage. On the other hand, it is very meaningful to simulate the natural lightning phenomenon to carry out the study of discharge mechanism.
