Lightning impulse voltage generator test device

Product Introduction

Lightning impulse voltage generator test deviceThe system is a test equipment that simulates high pulse voltage. In real life, pulse high voltage is often encountered. For example, in natural lightning strikes, very high pulse currents and voltages will appear at the lightning location, and high pulse voltages will also be induced in the surrounding area; For example, the switching operation of switchgear in the power system can also cause transient pulse voltage. These transient pulse voltage amplitudes often exceed tens or hundreds of kilovolts, which can cause equipment damage and endanger personal safety. Therefore, it is necessary to conduct experimental research on impulse voltage. On the other hand, it is also meaningful to study the discharge mechanism by simulating natural lightning phenomena.

Lightning impulse voltage generator test deviceIt is one of the basic items for high-voltage testing of power equipment. After the design, manufacturing, and repair of power equipment, impact testing is required to verify or inspect. Common power equipment, including power transformers, power transformers, high-voltage switches, combination devices, lightning arresters, power cables and accessories, bushings and insulators, all require impact testing.

The impulse voltage test is also one of the basic projects in high-voltage testing research. It is necessary to conduct impulse voltage tests in many aspects such as insulation coordination research, electromagnetic compatibility research, and discharge mechanism research. Therefore, impulse voltage testing equipment has a wide range of applications, and different specifications of impulse testing equipment can be seen in high-voltage testing laboratories in factories, research institutions, and universities.
