A Case Study on the AC Corrosion Effects of Gas Pipeline by High Voltage Induction in Submarine Tunnel

해저터널내 고전압 유도에 의한 가스배관의 교류전식 영향 사례 연구

This paper analyze the interference problems, especially AC corrosion when the gas pipeline is buried with power cable in the same submarine tunnel. This paper present the results of the study about AC corrosion, limitation of safety voltage, modeling of power cables, gas pipeline and grounding systems, analysis of induction voltage according to various circumstance, soil resistivity, length of tunnel. and so on.
