Instead of relying only on phase angles and discharge magnitudes accumulated over fixed intervals, PSA evaluates the ordered sequence of individual discharge events. For liquid or solid dielectrics, the externally applied phase angle is not a meaningful parameter; local electric field conditions at the defect govern ignition. Experiments with model defects and commercial apparatuses show characteristic event sequences and correlated parameters that distinguish single and multiple discharge sites.","cbCaioiNZ1R6f0uE","https://ap.wps.com/l/cbCaioiNZ1R6f0uE","pdf",786782,1,9,"English","en","# Abstract\n# 1.
