For more than 50 years, companies have performed partial discharge (PD) testing on electrical assets as part of ongoing predictive maintenance programs. Data obtained through PD testing and monitoring ...

Partial discharge (PD) is defined as a localized, high-frequency arcing that only partially bridges the insulation between multiple conductors or between conductors and the ground wall of an ...

Partial discharge (PD) measurement has been used for several decades to assess the condition of high voltage (HV) and medium voltage (MV) electrical apparatus. In the past, the application was mostly ...

What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

The oscillating wave test system from HDW Electric can be used to identify, evaluate, and locate partial discharge (PD) faults in a cable insulation and in joints and terminations. The system can be ...
