The aim of this paper is to present a grounding system modeling using a circuit network synthesized from its frequency response. This circuital representation allows simulating the grounding system in EMTP/ATP program considering its frequency dependent effects. Also, any electrical component may be included in the simulation, such as power system equipments or electronic devices. The frequency response was obtained by means of both an electromagnetic model based on the moments method (MM) and a hybrid electromagnetic model (HEM). The results were compared with previous works and field measurements, finding a good agreement.

The aim of this paper is to implement different grounding system (GS) models in order to compare its influence on the calculation of overvoltages in transmission lines, produced by direct lightning strikes. The models studied were a lumped DC resistance, a non linear resistance, and a synthesized circuit based on the frequency response of the GS. The latest model is proposed by the authors and takes into account the frequency dependent transient behavior of the GS.

This paper examines the influence of the lightning channel geometry, and the variation of the linear charge density with height, in a model for the first return stroke. The tortuous geometry of the discharge channel is simulated by means of statistical characterizations of natural lightning reported in the literature. The linear charge density for a channel with a tortuous geometry is modeled by means of a regression analysis of simulated data. Finally, the results presented, show a comparison between the spatio-temporal distribution of currents along a straight and vertical channel with those of a tortuous channel with non-homogeneous linear charge density.
