대지표면상태가 대지저항률의 측정결과에 미치는 영향

초록

In order to determine the actual earth resistivity for design of grounding systems. it is required to consider the earth surface and environmental conditions when measuring the earth resistivity. this paper presents the measured profiles of the earth resistivity associated with the earth surface conditions. The profiles of the earth resistivity are significantly dependent on the earth surface conditions. The curve obtained in disturbed test site is considerably sensitive to the freezing and the moisture present in the earth surface
