RESEARCH ON ELECTRIC POTENTIALS ALIGNMENT ON THE GROUND SURFACE WITHIN THE GROUNDING CONDUCTOR TERRITORY

Abstract

Results of research on distribution of electric potentials on the earth surface in the territory with a grounding conductor are analyzed. It is shown that potential over the center of a square grounding conductor can be higher than that over the electrode. It is suggested to estimate the limit size of the cell of a complex net grounding conductor depending on the depth of its laying. It is found that a two-level design of the grounding conductor reduces touch voltage. Novelty of the results consists in application of a mathematical model to investigating electric characteristics of a two-level grounding conductor versus its laying depth.
