Electric and Magnetic Field Minimization using Optimal Phase Arrangement Techniques for MEA Overhead Power Transmission Lines

In order to minimize the electric and magnetic fields generated by Metropolitan Electricity Authority (MEA) overhead power transmission lines, the optimal phase arrangement techniques were applied for 3-circuits overhead power transmission lines (69/230 kV). In this paper, the mathematical model was formulated using a MATLAB program which validated by comparing the simulated results with the measured results where the South Thonburi power transmission lines at Rama 2 Road (outbound side) were evaluated with the same conditions. Finally, it can be concluded that the optimal phase arrangement techniques can minimize the generated electric and magnetic fields lowering than that of the limitation given by the World Health Organization.
