Product Description

Partial Discharge Tester

Dari Electric recommends:

When partial discharge occurs in electrical equipment, electromagnetic waves are generated, which create a transient voltage signal to ground as they propagate outward. The magnitude of this signal is directly related to the intensity of the partial discharge and the distance to the discharge point. A specialized detector can be used for detection, and this detector is the partial discharge detector.

Main Technical Specifications
