Abstract

This paper was studied about the ultra-violet rays(UV) image area and discharge quantity of 22.9kV class polymer insulator using UV camera. The UV image area was begun to observe to 60kV that is about 40% of breakdown voltage of polymer insulator and the area was increased by applied voltage. Also, the discharge quantity was increased at 60kV sharply. If the intensity of breakdown passes over about 40% we can know that need the check on the electrical facility.
