Abstract
Degradation diagnosis of XLPE insulated URD cables was accomplished through out new method which was to be analyzed by non-electrical experiments and synthesized by degradation points. To supplement this method, It was also carried out using several electrical analyses PD-q increased generally in proportion to the applied voltage and showed no uniform patterns in relation to the thickness of insulator. Leakage current was unequal according to the thickness of insulator and its range was from 20[nA] to 50[nA].
