The Current and Magnetic Field Distribution Generated by Direct Lightning Strikes on Buildings Using FEM Analysis
Author: Hitoshi Kijima
Abstract: As a building becomes higher, a direct lightning strike to the building has been increased. When a direct lightning strikes the building, lightning surge current flow through the steel frames installed in the building. It is important to estimate the lightning surge current distribution inside the building in order to select appropriate SPDs (Surge Protective Devices) which have current capability depending on the size and the material. And also, it is necessary to analyze the magnetic field caused by the lightning surge current in order to find out the appropriate location of equipment taking into account of its immunity level against the magnetic field. In this paper, the analyzed results on direct striking lightning surge current and magnetic field distributions inside the buildings using finite element method were shown.
