Partial discharge (PD) denotes a localised electrical breakdown within the solid, liquid or gaseous insulation of a high-voltage transformer that does not completely bridge the electrodes. Over time, ...

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 discharges often occur due to impending insulation faults when electrical and acoustic pulses are sent out simultaneously. OMICRON's PDL 650 localizes the acoustic signals using multiple ...

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 ...
