Abstract

A transient grounding grid numerical model is developed. The results are compared with measurements done by other authors. The agreement between the simulations and measured data are completed with the comparison with theoretical results and concepts. Several cases with different soil parameters and grid geometry are presented. The transmission-line modeling method numerical technique was used to model, in time domain, the grounding grid. This model is suitable for practical applications related to lightning, short-circuit, and switching transients.
