Partial discharge and corona discharge testing service.

basic information

Partial discharge and corona discharge are phenomena where gas ionizes in areas of high electric fields, resulting in the occurrence of sparks. Although still not widely known, they degrade insulation performance and affect lifespan. High-voltage printed circuit boards, connectors, and connecting cables require caution. Inverter control devices, which are increasingly being adopted for energy savings, can also be breeding grounds for partial discharge and corona discharge. For those troubled by unexplained insulation failures, affordable contract testing is recommended. Please contact us for more details.
