Sažetak
This paper presents an analysis of transient behavior of grounding electrode under the soil ionization effect. The proposed numerical model offers the new approach to the transmission line modeling of a grounding system. The numerical model is based on the finite element method (FEM) applied to the transmission line equations in the time domain. The effect of the soil ionization on the dynamic resistance has been taken into account by dynamic change of the radius of the grounding conductor. Besides the soil ionization effect it will be shown the effect of soil permitivity to the dynamic resistance. The obtained results have been compared to the available experimental results from the literature.
