Safety Analysis of Fence Installation on a Large Power Station Concerning Inductive and Conductive Coupling from Nearby Transmission Lines

This paper presents a safety analysis during the installation of a fence surrounding a large power station under construction. The safety concerns are due to both inductive and conductive coupling from nearby existing transmission lines during steady state and fault conditions. The fence must be installed during the station construction phase and before the installation of its grounding system. Different scenarios are analyzed to ensure the safety during and after the installation of the fence. Based on the analysis, procedures for installing the fence to ensure safety at all times are developed. The analysis and the procedures presented in this paper can be used as a guide when carrying out safety analysis of fence installation under similar circumstances.
