CONSIDERATION INTO ACCELERATED AGING TEST METHODS FOR COMPOSITE INSULATORS

, , and .
(1995)

Abstract

Electrical and mechanical performances of polymer insulators are deteriorating with age. It is desirable to investigate the natural aging performance in the field However, it takes so long and it is not easy to analyze the natural aging characteristics. Various accelerated aging test methods are proposed and evaluated in the world. Evaluation results of typical artificial accelerated aging tests specified in the international standards on representative weathershed materials are introduced. Some considerations into the improvement of accelerated aging test methods are discussed.
