Abstract

This paper describes the insulation coordination scheme of line in distribution system when the direct lightning surge strikes. The BIL that is applied to distribution system is not properly considered the performance and operation of arresters. Because of that, the high BIL is being used at partial system. This paper variously analyses the lightning overvoltage of line and equipment with earth of overhead grounding wire and installation types of arrester. From these result. authors examine the rationality of BIL.
