It is a great challenge to differentiate partial discharge (PD) induced by different types of insulation defects in high-voltage cables. Some types of PD signals have very similar characteristics and are specifically difficult to differentiate, even

Partial discharge (PD) occurs when insulation containing voids is subjected to high voltage (HV). If left untreated, PD can degrade insulation until, eventually, catastrophic insulation failure occurs. The detection of PD current pulses, however, can

Current techniques used for monitoring the levels of contamination on high voltage insulators, such as leakage current and infrared, are not effective in dry conditions since they require the surface of the insulator to be wetted by fog, rain or snow
