要約(英語): Household appliances and information equipment with electrical circuits have come into wide use. These appliances and equipment seem sensitive to an electrical surge. In addition, a lightning might affect electrical systems not only on the lightning point but also on the systems at vicinity of the point. If the induced surges invade into low voltage distribution systems, it might cause severe damages to the appliances and the equipment. Therefore, it is necessary to investigate these induced phenomena. FDTD (Finite Difference Time Domain) method is often applied to analyze surge phenomena, which can treat analysis objects as three-dimensional circuits. For simulating these phenomena, we adopt VSTL rev. (Virtual Surge Test Lab. rev.) which is the surge analysis simulation program based on the FDTD method. In this paper, we discuss the investigation results regarding the lightning induced surge phenomena on low voltage distribution lines in a house and the relationship between lightning surges and a soil resistivity, and the effect on the surge phenomena by SPD (Surge Protective Device) on the low voltage distribution lines.
