HV lightning impulse generator is one of the basic projects of high-voltage test ingress of electric power equipment, which requires impact testing to be verified or tested after design, manufacture and repair. Common power equipment includes power transformers, power transformers, high-voltage switches, combined electrical appliances, lightning protection, power cables and accessories, casings and insulators, etc.
Impact voltage test is also one of the basic projects of high-voltage test research, which needs to be tested in many aspects, such as insulation cooperation research, electromagnetic compatibility research and discharge mechanism research.
Therefore, hv lightning impulse generator has a wide range of applications, in factories, research institutions and universities in the high-voltage laboratory can be seen in different specifications of impact test equipment
