抄録

This paper has derived analytical formulas of a voltage and a current on a grounding electrode by adopting a simple model circuit composed of R, L and C elements. Based on the formulas, its transient characteristic is discussed, and approximate formulas of the surge impedance and the propagation velocity are proposed. Also, this paper summarizes measured results of transient responses on grounding electrodes with horizontal and vertical arrangements. The characteristics of the measured results are estimated based on the analytical formulas derived in the paper. It becomes clear that most of the measured results show either an inductive or a resistive characteristic as far as the investigated cases in the paper are concerned. In the capacitive case, the transient resistance is not much different from the steady-state resistance. Also, it has been shown that measured steady-state resistances agree well with those evaluated by Sunde's formula for a horizontal electrode.
