Induced voltage behavior on pipelines due to HV AC interference under broken OHEW

Abstract

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.
