High voltage transmission lines are used to transmit bulk electrical power over long distances. As the voltage of transmission increases, the generated electric field also increases. The high levels of electric field have harmful effects on both human and animals. Therefore, corridors or right-of-way limits are left on both sides along the route of transmission lines. It is the purpose of this paper to study the effect of oil-pipelines which may run in the corridor and parallel to the conductors of the transmission line on the electric field distribution at and above ground surface level. A single pipeline is located in the transmission line corridor and the electric field on the ground surface is studied. The proximity of the oil pipeline from the line conductors on the field distribution is assessed to see if the amount of land which is required as right-of-way can be reduced or not. Oil-pipelines with different radii and fixed location from the transmission line arrangement center are simulated and modeled to present their effects on the field distribution and hence on the right-of-way limits. The effect of two parallel oil pipelines, separated by a certain distance and running parallel to the transmission line conductors on the field distribution is also examined. The charge simulation method (CSM) is used to simulate and model both the conductors of the transmission lines and the oil-pipelines. Graphs for the electric field distribution profiles at the ground surface, at transmission line conductors' surfaces and at the surfaces of the oil pipelines are presented and evaluated for the different cases mentioned above.
