Journal of the Korean Institute of Illuminating and Electrical Installation Engineers. 18:69-73
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 analy
