Abstract

This paper deals with the transient performance of zero signal reference grid(ZSRG) and insulated/isolated ground(IG) in case of lightning strike or surge currents in buildings. Using HIFREQ, which is a commercial code for electromagnetic field analysis, the difference of transient performances of ZSRG and IG type grounding structure have been presented based on the numerical calculations. It is expected that the quantitative and numerical calculation based analysis, which is adopted in this paper, will attribute to the selection of optimal grounding method in the intelligent buildings.

본 논문은 낙뢰나 스위칭 등에 의해 건물 내에서 발생할 수 있는 과도 현상에 대하여, 기준신호그리드와 절연/독립접지 방식을 비교한 것이다. 전자계 해석프로그램인 HIFREQ을 이용함으로써 정량적인 해석결과에 근거하여 건물내 접지방식의 차이에 따라 접지점에서 어떠한 과도현상이 발생하는지의 고찰이 가능하였다. 본 논문에서 시도한 건축물 내 과도현상 해석방법 및 사례연구 결과는 정보화 건축물에 필요한 접지 방식의 선정을 위한 자료로 활용될 것으로 기대된다.
