Popis: This paper presents the distributed source analysis approach for treating the inductive coupling of power transmission lines with buried pipelines. The evaluation of the induced voltages in a pipeline which share the same path with a power line for a monophasic short circuit on the line is performed and also the analytical expression for current density induced in soil is calculated. The paper describes a practical case of subdivision of the zone of influence in sections (a circuit model) and a precise calculation of the induced voltages in different points based on the measured data, is performed in Mathcad, using special interpolation functions.
