摘　　要：Recently, a lightning surge is recognized as one of the biggest risks to the society. If the surges induced by lightning invade into low voltage distribution lines, there might be a possibility of giving some severe damages to the systems. Therefore, it is necessary to examine these induced phenomena. FDTD （finite difference time domain） method which treats objects as three-dimensional solid circuits is applied to analyze these induced phenomena. VSTL （Virtual Surge Test Lab.） is the surge analysis simulation program using FDTD method. In this paper, the lightning induced phenomena on the low voltage distribution line in the house are analyzed by using VSTL. In this paper, investigation results about induced surge when a lightning struck the point nearby the house, and about a suppressing effect of surges by comparing the results of analysis with and without SPD （surge protective device） are shown. As a result, it is confirmed that SPD is effective for suppressing lightning surge.
