Abstract :
Equations and graphs given in IEEE Std 80 to determine ground resistance are not accurate and give conservative results. More accurate equations and graphs for determining the ground resistance of the human foot in a substation with a thin surface layer of gravel are given. An analysis has been made for models of the foot. In one model the foot is represented by an equivalent circular plate and in the other by an equivalent rectangular plate. Results obtained with these two models and with the IEEE Std 80 method are compared
