Abstract

This paper deals with the seasonal variation of soil resistivity and the special characteristic for ground rods by lapse of time. The ground resistance was changed by humidity, temperature of earth and earth resistance. In this experiment, we studied the resistivity during the period from June 1995 to May 1996 by the soil and the corrosion of the ground rods. As a result, the soil resistivity during the period are appeared minimum in summer and maximum in winter. The loss in weight of Fe rod appeared higher than Cu, Al, Cu-Zn, and St. In the lapse of time, Fe rod was reduced 1.2 % later two years and 1.95 % later three years in weight. Cu rod was defected oxygens of 14.7 % later two years and 30.3 % later three years by EDX.
