The Point Ground Electrode in Vicinity of the Semi-Spherical Inhomogenity

Abstract

Characterisation of the point ground electrode placed in the surroundings or inside of the semi-spherical earth inhomogenity and fed by low frequency (LF) current using isolated earthing conductor, is presented in this paper. The ground impedance (resistance and reactance) and potential distribution on the ground surface are determined. Image theory for two-layer semiconducting media, as well as for the one point electrode placed nearby or inside of the spherical body is used during the analysis.
