Abstract
In this paper, we carried out an comparative analysis on ground impedance of single copper-, three linked copper- and single carbon- electrodes by the application of various current sources such as sine, square, and surge with fast risetime. Impedance of single-copper electrode was the highest among them and was affected as the amplitude and the frequency of applied current. However, impedance characteristics of the three linked copper- and the single carbon- electrodes showed a similar tendency.
