This paper investigates the interference between electromagnetic field produced by high voltage power lines and liv ing organisms and metallic objects underneath the transmission lines such as ships, at rivers crossing, and vessels passing under or near to power lines. Metallic pipelines buried in the same corridor are affected with many factors, na mely : the power line configuration, separation distance between transmission line and pipeline, separation distance between conductors, the transmission line tower height, existence of the earth wire, the sequence of the power supply, the length of corridor and the fault conditions. The equations of magnetic fields of the transmission lines and the density of currents induced in the human bodies and metallic ships surface were introduced. The induced voltage on the neighbouring pipelines was calculated. A computer program was developed to model and simu late the magnetic fields produced by power lines. The program calculates the current density induced in objects underneath or in the neighbourhood of the transmission line. The results obtained using the developed program illustrated to be consistent with previous literature results. The obtained results showed to be satisfactory and consistent with the experimental ones.

“…This interference has been measured for many years; numerous countries stimulated their own standards and designated the maximum acceptable induced voltage in pipeline running parallel to the HV line. The most frequently used equations to compute the induced voltage are Westinghouse and Carson equations [1]. The AC interference on a pipe line announces the following hazards [1][2]:…”

High voltage infrastructure upgrade is expending due to the growth in populations. To save on easement cost and to reduce the environmental impact of these projects, HV transmission lines occupy the same easement as pipelines in many cases. This joint easement introduces the AC interference between transmission lines and pipelines. The induced voltage can reach a limit which will jeopardize the human safety. The cited research studies the induced voltage under the presence of the OHEW using the shielding factor. The works under this paper study the induced voltage using the OHEW section current along with the superposition theorem. The simulations are compared to the existing research methods. The case study along with the theoretical study discusses the impact of a broken OHEW on the induced voltage using the existing research methods and the proposed method.
