This paper describes the using of software programming for the substation grounding system which is designed for worker’s safety. This grounding system presents new method to increase grounding resistance of Human Foot. The new method can decrease the number of conductors of an unequally space grid and it is a supplement to ANSIDEEE std. 80 - 1986. It also uses 10 - 30 percents less grounding grid material for safe and economical design. This paper also presents touch and step voltage for a safety design.
