Abstract

We propose an algorithm of analytical measurement which can separate conductive and dry-band arc components of leakage current flowing on the surface of polymer insulating materials according to the waveform distortion considered. The waveform distortion gives useful information to distinguish discharge types and evaluate the degree of degradation of the polymer surface. We have also developed a measurement system capable of separating the leakage current into the two components. We confirmed effectiveness of the measurement system by applying it to an artificial aging test based on Rotating Wheel Dip Test method.
