Abstract :
A detailed analysis of potential profile at a surface above energized unequally spaced grounding grid has been carried out, for soils with multiple layers. Exact and approximated algorithms are used to obtain the voltage profile and then to calculate the step and touch voltages. The analysis shows that the voltage distribution is highly dependent on soil structure type and characteristics and also the spacing between conductors.
