A study for the development of arcing horns in 154kV T/L

154kV 송전선로용(送電線路用) Arcing Horn 개발(開發)에 관한 연구(硏究)

154kV insulator strings are frequently damaged by lightning strokes, overvoltage and contamination. And this insulator damage inflicts a loss on the power company. The purpose of this paper is to develop the arcing horn as a protective device of 154kV insulator strings against lightning flashover and overvoltages. So We have developed the arcing horn which is suitable for 154kV transmission line and estimated the performance of arcing horn by high current arcs and high voltage tests.
