Abstract

The back flashover caused by lightning could make serious damage to electrical and electronic systems within the structure under lightning stroke, and international lightning protection codes pay great attention to the problem. In this paper, FDTD method is adopted to calculate waveforms of the transient potential rise in the steel structure when the roof corner struck by lightning. Moreover, the peak distribution of the potential on each floor is discussed. The conclusions will provide theoreticcal reference for EMC design inside a building.
