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.
