Abstract
ln most high-voltage switchyards, basic grounding systems are formed by a grid of horizontally buried conductors. A method is developed to determine more accurately the resistance of such grounding systems. The dimensions are those usually encountered in practice with the conductors buried near the surface of the earth. The varying soil resistivity may either increase or decrease with depth according to a certain law, which can represent most of the soil conditions that normally occur in practice. The computed results check well with data obtained from tests in substations which are in service.Keywords
