Electromagnetic Interference between Electrical Power Lines and Neighboring Pipelines

Electromagnetic Field interference caused by electric power lines sharing the same corridor with pipelines can produce the unsafe operation of the protection and measuring systems of the pipeline under both normal and faulty conditions. Voltages can be induced on the pipelines from power lines in the areas where they run in parallel together. These voltages vary with the electrical characteristics and geometry of both systems. These voltages can affect the operating personnel, pipeline associated equipment, cathodic protection and the pipeline itself. Mitigation is required to reduce the voltage levels to limit that adverse effect for personnel and pipeline.
