초록

Grounding grid design of substation and power generating plant has been conducted based on IEEE Std 80 or 665, which provides simple formula to estimate grounding performance such as grounding resistance, max. step and touch voltage. Although these formula are applicable for many situations, they contains many assumptions and consequent limits of application. This paper shows the limits of IEEE formula and the virtue of estimating grounding performance of grid using numerical method or computer program.
