EMTP-Analysis of Sheath Circulating Current on Underground Transmission Cables
EMTP를 이용한 지중 송전 케이블의 시스 순환전류 분석
Abstract
This paper describes an improved analysis method for sheath circulating current on three-underground transmission cables using EMTP(Electromagnetic Transient Program). Author studied diversely the sheath circulating current on three-underground cables depending on the various length rate, the phase arrangement, and the grounding resistance of the sheath in the cross-bonded section. It was clear that very large circulating current is generated in cable systems due to unbalanced length rate and phase arrangement in the cross-bonded section. The analysing method for two or more underground cables will be really Improved for cable system utility.
