The term partial discharge (PD) refers to a bridging of insulating material between electrodes that sustain an electric field in high-voltage (HV) systems. Long-term PD activity can lead catastrophic failures HV systems resulting economic, energy and even human life losses. Such losses be avoided by continuously monitoring activity. Existing techniques used for localization including time arrival (TOA) difference (TDOA), are complicated expensive because they require synchronization. In this...
