Abstract
Excessive step and touch potentials near high voltage transmission line structures due to severe ground faults present a hazard to anyone in proximity to a structure when a fault occurs. This paper extends the probabilistic analysis of step and touch potentials near transmission line structures reported at the 1982 IEEE Summer Power Meeting [1] and presents a complete computerized methodology for assessing the overall effectiveness of grounding for any given network and right-of-way conditions. The paper also illustrates some applications of the method in the Ontario Hydro system.Keywords
