Simulation of Lightning Transient Responses of Grounding Grid Using Finite Element Method

Abstract

This paper presents the application of the Finite Element methods to calculating and modeling the lightning transient responses on grounding grid. The uniform and optimized grids are used in this work. The tested results obtained on many different models of the conductor and grids have seen the effectiveness of the proposed method and the influence of conductor compression to the transient values when the lightning current into the grid at the different positions.
