Influence Of Soil Electrogeological Properties On The Impact Point Of Lightning Discharge
Authors : Mehibel H. . Ferras J. .
Abstract
In this paper, we present some results of investigations carried out on the effect of soil heterogeneity and conductivity on the strike point of lightning discharge using mathematical and experimental model. The mathematical model simulates the propagation of negative downward leader, it shows that the electric field in the soil interface depends on the conductivities ratio of the heterogeneous soil. In the experimental model we observed that the conductivities of the heterogeneous soil and the distance from the interface, affect the discharge attraction to the soil interface. The use of experimental model parameters in the mathematical model, shows a concordance between the two models.
