Formulas for Calculating Grounding Resistance ...

Solution of ground enhancement material application for decreasing resistance of grounding system is a current problem that is interested by scientists [1]-[2], especially, a grounding system is installed in small area or high resistivity of Soil. In order to determine the grounding resistances of simple forms (horizontal rod or vertical rod) we can use the given software [3] or the calculating formulas [4]. This paper presents some other formulas for calculating a grounding resistance of simple forms with ground enhancement material. Calculated results from the formulas of this paper were verified by the results of [4] and the results from the grounding calculating software of ERICO Company.
