Calculation of Indoor Electromagnetic Field Induced by Lightning Strike Based on Finite Element Method
Xiaohong Huang · Low Voltage Apparatus · 2010
The distribution of indoor electromagnetic field in a building struck by lightning was analyzed by the finite element method(FEM).For the same building,the comparison between the results by the FEM and the existing circuit method was carried out.It was pointed out that the advantage of FEM was it could consider dispersing current in the earth.The results showed that FEM could be applied to the evaluation of electromagnetic environment in buildings struck by lightning.
