Partial Discharge Tester PD Spot Detector
Artial Discharge Test Instrument, Partial Discharge Test Kit. PD Measuring Device
Applications
A Partial Discharge (PD) Tester, also known as a PD Detector, is a device used to measure and analyze partial discharge activity in electrical insulation systems. Partial discharge is a phenomenon that occurs in insulation materials when there is a breakdown of the dielectric strength, leading to localized electrical discharges. These discharges can degrade the insulation and eventually lead to equipment failure.
