Modeling of inductive coupling on aerial metallic Pipeline from HV overhead power line

The main aim of this paper is to analyze the inductive coupling between a HV power line of 220 kV and an aerial metallic pipeline. Typically, this is done for safety reasons concerning the maintenance operators and the pipeline integrity. The results achieved show that the presence of metallic pipeline near these power lines disrupts the magnetic induction, the induced voltage and the discharge current values through the human body according to the location of the pipeline exceed the safety margin and may be a major source of risk and damage for personnel coming into contact with the pipeline and for equipments connected to the metallic pipeline, therefore, in order to eliminate these risks, the mitigation measure is highly recommended, it is enough simply to connect the both ends of the pipeline to earth with appropriate resistances. The obtained simulation results were compared with those obtained by Carson approach, a good agreement was obtained
