초록

This paper presents the ground surface potential rises caused by a counterpoise buried in two-layered soils. To propose fundamental data relevant to the risk reduction of electric shock of human beings, the ground surface potential rises near the counterpoise were computed by CDEGS program. Touch and step voltages are calculated on the basis of the distribution of the ground surface potential rises. As a result, touch and step voltages, ground surface potential rises depend on the soil resistivity of installation point of counterpoise in the two-layered soil structure.
