Lab Equipment Supplier Hv Impulse Voltage Testing Equipment

Impulse voltage test system can be used to generate lightning impulse (1.2±30%/ 50±20%μs), LI (T1:1~5μs, T2: 40~60μs) for cable testing, chopped lightning impulse(chopped time between 2~5μs to test power transformers, instrument / voltage transformersandbushings), switching impulse (250±20%/2500±60%μs)and steep front wave forms(to test glass insulator, composite insulators or ceramicinsulators).

1It is used to test the insulation strength of power equipment (such as transformers, circuit breakers, insulators, etc.) under impulse voltages like lightning and switching overvoltages, ensuring the safe operation of equipment in extreme voltage environments.
2.In the production and manufacturing process of electrical equipment, it tests the impulse voltage tolerance of products, screens out unqualified products, and ensures the quality and reliability of equipment leaving the factory.
