SPD(Surge Protective Device) is very important in LPS(Lightning Protection System) to protect vulnerable electrical and electronics devices from surges caused by lightning strokes or switching. Also SPD should be installed with shot lead line to protect electronic installations. But this paper finds the fact that almost SPDs have been installed with lead line exceeding 0.5m in apartments. This paper suggests the improvement of SPD installation method with equipotential bonding bar to eliminate voltage caused by lead line impedance. Suggested method was certified by experiment with excellent performance.
