We have been analyzed the interference problems already in steady state, especially AC corrosion when the gas pipeline is buried with power cable in the same submarine tunnel. In the next stage, we analyze the induced voltage in a fault condition of 154[kV] underground T/L. This paper presents the results of them which are limitation of safety voltage, modeling of power cables, gas pipeline and grounding systems, analysis of induced voltage in a fault condition, and protection of power line system.
