Influence of Alternating Current Electrified Railway Stray Current on Buried Pipelines

By setting up test equipment to simulate the actual situation, the interference law of stray current of alternating current (AC) electrified railway on buried pipelines under the condition of parallel and cross was obtained. The formula of pipe-to-soil potential of buried pipelines under different working conditions was obtained by theoretical analysis. Based on it, a forecasting software was edited, which provided theoretical basis for stray current protection.
