Determination of Electrical Quantities in the Traction Rail Network and Buried Pipelines Located Under the Influence of Stray Currents from Electrified Railway Transport

摘要

The paper presents a system consisting of a traction rail network and two buried pipelines located under the influence of stray currents from electrified railway transport. Analytical expressions for the calculation of the distribution of electrical quantities in the two buried pipelines with their mutual influence were obtained. Expressions were obtained using Hartley integral transform. The program, allowing monitoring the changes of electrical quantities in traction rail network and two buried pipelines at the movement of locomotives on track section, was developed. Also the proposed program calculates and writes the potential of the buried pipeline relative to copper-sulfate reference electrode to the file, which allows estimating the need for corrosion protection from stray currents from electrified railway transport.
