  • Abstract
    PD measurements have been used in the after laying test for high voltage XLPE power cable lines because PD is sensitive to defects in a cable system. However, the PD characteristics for defects in XLPE cables or joints strongly depend-upon the type or the size of defects. They also change with time. Their details are not well understood yet. In this paper, the PD characteristics of a thin void between low-density polyethylene and electrode have been investigated. Especially, the change in PD characteristics with time and the time delay of the PD detection in the after laying test of XLPE cable line were discussed.
