Abstract
A model, by which why ac charging current of water-treed insulation contains higher harmonics is explained, has been developed by the authors. The aim of this paper is to discuss the ac loss current of a penetrated water-treed XLPE by using the model because the sample without a healthy region more directly tells us the dynamic behavior of interconnecting channels between water-filled voids. It has been found that the conductive region where channels are filled with water from voids grows under voltage application and the length of it reaches the whole penetrated water-treed region.
