매설강관에 대한 전파상수는 대지도전율에 의한 매질 영향을 받기 때문에 대기중에서의 해석과 같지 않고 복잡한 초월식을 풀어야 하는 어려움이 있다. 이러한 매설관에 대한 전파상수 해석에 관하여는 Wait의 논문에서 연구되어 있고 이것을 근간으로 일본과 미국에서 각각 전송선 이론에 의한 초월식을 실용적으로 수립하여 제시하고 있다. 본 논문에서는 매설 강관에 대한 몇 가지 다른 형태의 전파상수 계산식에 대하여 시뮬레이션을 통한 값을 다루어 보고 유도전압에 대하여 적절한 산출 적용이 되는 지 검토하여 본 바 정학한 계의 해석에 의한 것과 Wait 근간의 일본 방식에 의한 계산값이 유사한 것으로 도출되었다.
