Wire Grounding Electrode near Vertical Cylindrical Non-homogeneity

Satisfactorily accurate approximation of soil inhomogeneity providing simple determination of the soil structure influence on grounding system characteristics is important part of the procedure for grounding system analysis. Very often, ground non-homogeneity can be approximated as vertical cylinder tube (wells, various tubes, pillar foundation etc.). The method based on using of Method on Moments and Green's function, applicable for analysis of grounding systems placed in the surrounding soil of this type non-homogeneity is presented in the paper.
