The Study on the Impulse Characteristic of Secondary Arresters in Power Distribution System

배전급 저압피뢰기 임펄스 특성 연구

The overvoltage generated by the lightning strokes has been doing considerable damage to the distribution network as well as the consumer facility until now. Because most of the lightning strokes are accompanied by a storm, the aftermath of damage to the consumer is so serious. Therefore it is very important to survey the optimal operation plan by the field test of distribution lightning facilities. In this paper we have accomplished the field test to verify the impulse characteristic of Secondary Arrester(SA), and analyzed the effect of the SA in power distribution system.
