摘要：

When lightning strikes an apartment building, transient voltages are generated or induced in electrical and telecommunication wires in the building. The transient voltages may cause malfunctions or failures of electronic or telecommunication appliances. Therefore, it is necessary to know the spatial distribution of voltage, generated by typical lightning, in the building. Although there are several works studying lightning-generated voltages in buildings, they do not consider the presence of concrete that accommodates steel structures. In this paper, lightning-induced voltages between wires in a simplified apartment building struck by lightning are computed using the finite-difference time-domain (FDTD) method, taking into account the presence of reinforced concrete. On the basis of the computed results, the effect of the presence of concrete is discussed. (c) 2022 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
