Insulator, polymer, leakage current, waveform, hydrophobicity
Polymer coated insulators are used to suppress the pollution phenomenon on high voltage insulators. In order to investigate surface activity, which is directly linked to insulation performance and lifecycle, leakage current waveforms are used. In this paper field measurements are used in order to correlate leakage current waveforms to certain surface activity directly linked with hydrophobicity.
