Abstract

Metal pipelines used to transport gas and other chemical products are protected by insulating coatings as well as cathodic protection systems. These pipelines sometimes are passed near the power lines, causing induced AC voltage on them. Increasing the AC voltage amplitude on the buried pipelines will increase the risk of electric shock, electric sparking between the equipment connected to the pipeline and the ground or adjacent metal structures, increasing the rate of insulation damage to the pipelines, disrupting the functioning of the cathodic protection system as well as increasing the AC corrosion of pipelines. Therefore, it is necessary to study and evaluate the factors affecting the inductive AC voltage level and provide effective solutions to reduce its destructive effects. In this paper, the inductive voltage of overhead lines on the buried metal pipeline has been investigated under normal conditions of the power system. The amount of induced voltage on the pipelines depends on some factors such as the current of the transmission line, the number of transmission line circuits, the arrangement of the phases, and the distance between the transmission line and the underground pipeline.
