The objective of injection of third harmonic voltage in transmission lines to reduced peak amplitude of phase voltages. In this proposed method, 13.4 % of peak amplitude of phase voltage is reduced by injecting third harmonic voltage in fundamental component of phase voltage and line to line voltage remains intact. The third harmonic voltage could be injected through line or neutral of transformer. Injected third harmonic voltage does not affect or generation or load side. In this method impact of third harmonic voltage only in phase voltage And does not affected on line to line voltage. With this approach, the existing transmission line can be upgraded by increasing voltage level. In proposed method required less ground clearance compared to practical transmission lines by injecting third harmonic. Furthermore, the capital investment of new construction transmission line could be reduced by shorter length of tower. The loadability of existing transmission lines can be increased, if clearance of new phase to phase is met. In this paper, operation of the electric power transmission line with injected third harmonic voltage and practical consideration for its implementation is studied

Keywords- third harmonic voltage, power transmission, ground clearance, line upgrading, and line loadability
