“…Due to environmental and economic reasons, mainly related to construction costs and to their impact on local ecosystems high or medium voltage power lines are forced to coexist in a relatively narrow distribution corridor with gas, petrol or water pipelines with no access to new separate rights-of-way [1][2][3]. Figure 1, shows such a situation when an underground metallic pipeline is in the close proximity with an overhead power line.…”

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.
