반구형 축소모델을 이용한 접지전극 주변의 전위상승 분석

This paper describes the ground surface potential profiles near the object to be grounded. The hemisphere water tank was used to simulate the scale model. As a result, the ground surface potential near the ground electrode was considerably raised. In particular the ground surface potential at the just upper part of ground rod was higher than other part. The ground surface potential was lowered with increasing the buried depth of ground rod.
