Performance comparison of overhead line under various load conditions

An overhead line is an electric power transmission line suspended by towers or poles. Since most of the insulation is in the air, overhead transmission lines are generally the lowest-cost method for transmitting large quantities of electric power over long distance. In this paper, the performance of overhead lines is studied under 3 different load conditions. The conditions are: noload, matched-load and short-circuit loads. We focuses on the four parameters of voltage, current, real power and efficiency. The study is conducted using MATLAB/ Simulink. According to simulation results, it has been shown that the performance of the transmission line under different load conditions is varied.
