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. © 2022 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

钢筋混凝土对公寓楼雷电浪涌影响的 FDTD 模拟

当闪电击中公寓楼时，建筑物中的电线和电信线会产生或感应出瞬态电压。瞬态电压可能导致电子或电信设备的故障或故障。因此，有必要了解典型闪电产生的电压在建筑物中的空间分布。尽管有几项研究建筑物中雷电产生的电压的工作，但他们没有考虑容纳钢结构的混凝土的存在。在本文中，考虑到钢筋混凝土的存在，使用有限差分时域 (FDTD) 方法计算了被雷击的简化公寓楼中电线之间的雷电感应电压。根据计算结果，讨论了混凝土存在的影响。© 2022 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
