Abstract
This study describes the results of aging characteristics of polymer insulators through the tracking wheel test. In order to evaluate the reliability of polymer insulators, 4 polymer insulators which used in the field were selected. Electrical tests such as power frequency voltage test, steep-front impulse voltage test were performed after tracking wheel test. Chemical structure and contact angle were measured for investigating an aging characteristics. Although some changes have occurred on the surface of insulator, there are no critical changes between new and tracking wheel tested insulator.
