Abstract

Degradation diagnosis of XLPE insulated URD cables was accomplished through out new method. which was to be analyzed non-electrical experiments and synthesized by degradation points. To supplement this method, it was also carried out using several electrical analyses. Breakdown voltages were measured and breakdown lifetimes were Predicted appling for Weibull distribution function. As a result, breakdown lifetime in failure cables was shorted up to 1/3 times than that in general cables. It was very available to estimate cable degradation using above method, but it needs further study on XLPE insulated URD cables in order to improve reliability.
