要約(英語): With the advent of highly advanced information-oriented society, the appliances connected to the telecommunication line come to be widely used in the house, and it is reported that these appliances are frequently damaged by lightning. The home electric appliances have a built-in SPD (Surge Protective Device), damaged with the excess of the amount of charge passing through. In this paper, the authors estimate the lightning surge on an indoor distribution line by using the VSTL (Virtual Surge Test Lab. ) where the FDTD (Finite Difference Time Domain) method is adopted. The accuracy of the calculated results by the VSTL is verified by comparison with the experimental results. The lightning current resulting in the damage of the SPD of the home electric appliances is investigated in the case of the direct strokes to the concrete pole where not only the 6.6kV distribution line but also the low-voltage line are installed, and it turns out that the estimated damage rate reasonably agrees with the reported rate.
