An Analysis of Grounding Methods for Safety of Linemen in Distribution Line

배전선로 작업안전을 위한 최적접지 방법 평가

This paper presents an analysis which compares the effectiveness of different temporary safety grounding methods on working overhead distribution system. The analysis studied direct energization at fault conditions with seven scenarios. The results show that the scenario, single point safety grounding on the working pole with brackets Pairs spaced 2 km apart on both side of a work site is safest grounding method. This can be used to evaluate lineman safety on a overhead distribution systems in Korea.
