Abstract :
The authors present some experimental tests and numerical results on the impulsive response of ground systems when nonlinear ionization phenomena take place. The aim of this work is to verify the reliability of the code in the behavior analysis of a ground system excited by high impulsive currents. Experimental tests and numerical results are presented for some typical configurations of ground electrodes
