Alternative Approach to “Grounding Resistance of a Hemispherical Electrode Located on the Top of a Finite-Height, Cone-Shaped Mountain”

An alternative approach is proposed for the analysis of the low-frequency response of a small hemispheric grounding electrode on the top of a cone-shaped mountain with finite height. This article revisits a subject that was treated in three previous articles with an incremental improvement. The geometric profile of the bottom of the cone is theoretically focused. The crucial influence of the terrain profile is reconfirmed in the evaluation of the grounding resistance for an elevated terrain.
