Characteristics of Lightning Impulse Current of ZnO Block for Transmission Line Arrester with External Gap
송전선로에 사용되는 갭형 피뢰기 소자의 뇌임펄스 전류특성
Abstract
This paper describes the characteristics of lightning impulse current of ZnO block for transmission line arrester with external gap. The ageing parameters of lightning arresters are impulse current, moisture ingress, temperature ageing and so on. Especially it is important to estimate the change of electrical characteristics by impulse current. Total energy applied to the ZnO arrester each time is
