A Study on the Separation Distance to Protection of Buried Pipeline from Arc Strikes Caused by Power Line Ground Fault Current

지락사고시 지중금속배관에 대한 아크이격거리에 관한 연구

The demand of the power and gas energy have been rapidly increasing with the industralization, therefore, the area where buried pipelines run parallel with the adjacent power lines and cross them increases in Seoul as well as other cities. These situation cause AC interference from the power lines. However, there aren't any standards to preserve the pipelines from AC interference in Korea. This study introduces the separation distance to protection of buried pipeline from arc strikes caused by power line ground fault current. And this study examines and compares the arc distance through case study.
