Résumé(disponible en anglais seulement)
Induction in the pipeline due to AC interference is a phenomenon that should be taken into account for planning and mitigating purposes. To evaluate the electric currents and voltages produced in the pipeline due to proximity of high voltage power lines, Transmission Line Theory (TLT) is often applied and a number of software packages using TLT has been developed.
In this paper the analytical approach to the problem of the AC induction in an infinitely long multi-layered cylinder representing the pipeline has been used to evaluate effects of the different electromagnetic parameters of the pipeline and surrounding medium. Also, approximate formulas for pipeline steel impedances and coating admittances used in industrial software have been compared with the exact formulas and the results of the comparison are presented.
