EMTP를 이용한 배전계통의 접지시스템에서 직격뢰에 의한 도전성 EMI 영향 분석

This paper presents analysis of conductive EMI by first short stroke on the lightning protection system of the low-voltage distribution system using EMTP(Electro-Magnetic Transient Program). For the analysis, we propose a method for computing the effects of a direct lightning stroke on the lightning protection system of the low-voltage distribution system using EMTP. It has been possible to simulate many case but we selected some basic cases based on typical low-voltage distribution systems.
