Abstract
The increase in population forces High Voltage (HV) substation to be constructed within proximity of residential properties. These substations are fed by transmission mains. Based on existing standards, transmission mains structures have an earth grid that solidly bonded to the substation earth grid using the OHEW system. This bond transfers the substation earth potential rise under a fault condition to numerous transmission poles. This transfer could reach an unsafe condition and jeopardize the safety of the public. In addition, to save on easement cost and reduce the impact on the environment, transmission mains use joint easement with pipelines. This joint use easement introduces the induced voltage issues. This paper endeavours to provide a novel layout for the steel poles to control the pole EPR under substation fault. The works show the impact that the new proposed method has on the substation EPR and the induced voltage on pipeline for a shared easement. A Case study is also addressed to support the proposed theoretical study.
