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 ...

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 ...

As emerging technologies reshape asset management, the electrical testing industry stands at a turning point—yet for decades, it has relied on periodic field testing as the backbone of condition ...

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 ...
