Abstract
In today's world, a growing concern among power utilities' workers regarding the possible health hazards associated with the exposure to the electric field of the HVAC overhead transmission lines. Hence, this paper aims to find the electric field distribution under a 380 kV double circuit overhead transmission line. Each phase has four bundles and arranged in a vertical configuration. The HVAC transmission line is modeled in MATLAB based on actual data for a standard 380 kV overhead transmission line of the Saudi National Grid (NG). Using the charge simulation method (CSM), the electric field exposure level has been computed at three distinct levels under the transmission line. These levels are ground level, head level, and close Maintenance level. The electric field profile for each scenario has been plotted. Finally, the simulation results are compared with the maximum allowable exposure limits defined by three different international standards.
