Electrical Characteristics Evaluation of Transmission Line Arresters

송전선로용 피뢰기의 전기적 특성 평가

It has been reported that more than 50% of breakdown in transmission line for 154kV and above is due to lightning stroke. The flashover failure due to lightning stroke causes outage, voltage drop and instantaneous outage, Therefore line arrestors have been used in transmission line for protection from lightning stroke. In this paper, we describes electrical characteristics and performance test of line arrestor for transmission line.
