Study on Evaluating the Transient Electromagnetic Field Caused by Different Lightning Stroke Modes Using FEM Method and Circuit Method
In order to solve the problem that it is difficult to predict the transient electromagnetic field of lightning, this paper attempts to use the circuit method to estimate the current of each branch of metal structure when lightning strikes, and realizes the simulation of space transient electromagnetic field by finite element method (FEM). In this paper, the lightning protection methods of a metal frame are comprehensively analyzed, and the lightning stroke simulation of various lightning protection modes of a metal frame is carried out by using the above methods, and the indoor transient electromagnetic field is evaluated, and its spatial distribution characteristics are analyzed.
