OMICRON's PDL 650 localizes the acoustic signals using multiple sensors spread out over the transformer. Partial discharges often occur due to impending insulation faults when electrical and acoustic ...

Power cables are important assets in electric utility transmission networks for the reliable operation of power systems. To prevent catastrophic failures in underground cables and terminations, it is ...

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 ...

The constant availability of medium- and high-voltage electrical assets used in the generation, transmission and distribution is important for a reliable power supply at both utilities and also ...
