Grid-Ground Electrode in Two Layered Non-Homogeneous Ground
In this paper, a procedure including using of the Green’s functions for a point source in multilayered media for the electric scalar potential and the Method of Moments-MoM for analyzing described problem is adopted. The approach provides generating Green’s function of the point source for arbitrary number of homogeneous layers. Also, it is possible to

Impulse Efficiency of Ground Electrodes [PDF]
The lightning current waveform has a major influence on the dynamic performance of ground electrodes. While high lightning current intensity improves the dynamic grounding performance due to ionization of the soil, very fast fronted pulses might worsen the performance in case of inductive behavior.
