要約(英語): The surge characteristics of a grounding conductor are quite different from those of an overhead wire. It is difficult to represent the characteristics of a grounding conductor in time domain without numerical simulation. This paper describes approximate formulas for voltage and current in a horizontal grounding conductor. The formulas are derived in time domain on the basis of the lattice diagram method, and are very simple. It is convenient from the engineer's point of view to do rough estimation of surge characteristics of a grounding conductor by the approximate formulas. Some empirical laws on the grounding have been employed without any discussions. The surge characteristics of a grounding conductor are discussed using the approximate formulas.
