Abstract :
This paper deals with partial discharge (PD) causing degradation of XLPE cable joint and interfacial phenomena of XLPE/EPR interface due to artificial defects such as metal particles, needle-like void and fiber soaked with water. We measured aging time dependence of phase-resolved PD (phi-q-n) patterns and PD statistic parameters when such kinds of defects were placed at XLPE/EPR interface. As a result, phi-q-n patterns were found to depend upon the defect type varying with aging time. In order to grasp the degradation mechanisms, we compared a practical XLPE cable joint with a model sample to simulate the real one. Moreover, electron spectroscopy for chemical analysis (ESCA) was also carried out to interpret the degradation mechanism.
