국립전파연구원 고시인 전기통신설비의 기술기준에 관한 표준시험방법에서는 통신 설비에 대한 접지 저항 측정 방법으로 현재 2개의 보조극을 설치하여 측정하는 3점전위강하법을 사용할 것을 권고하고 있다. 하지만 이 방법은 보조극을 설치하기 위한 공간의 확보가 어려운 지역이나 험준한 산악 지역, 암반 지역 등에서는 적용이 불가능하여 현장에서의 어려움이 예상되고 있다. 이에 IEEE와 ITU-T에서 기준이 되는 접지저항값의 만족 여부 확인만을 위하여 제시하고 있는 2극 측정법을 알아보고 테스트베드를 이용한 시험 측정을 통하여 3점전위강하법과 2극 측정법에 의해 측정된 접지저항을 비교 분석하였다.
