Abstract (English):
Steel pipelines for transporting oil and gas can run along the routes of AC main railways. As a result of the electromagnetic influence of traction networks on pipes having insulating coatings, voltages can be induced that are hazardous to personnel who operate the pipeline. The report addressed the issues of modeling the electromagnetic effects of a promising traction network of 94 kV on a steel pipeline with a diameter of 250 mm laid on the surface of the earth. Computer simulation showed that at a distance of 100 meters from the railway line to the pipeline, the maximum induced voltage reaches 100 V, which is more than one and a half times the permissible value. This factor must be taken into account when designing prospective traction power supply systems in the areas of their convergence with main pipelines
