This paper examines the effects of wind environment on high voltage transmission lines span. Proper analysis of wind and its effects is important on high voltage transmission lines for the purpose of continuity and quality of electrical services. Strong wind has the potential of causing unexpected damages to conductors and thus erupting power transmission of the system. Various literatures on wind effects on high voltage transmission lines were reviewed. The various effects of wind environment on high voltage transmission lines span as well as possible solutions to these effects were examined.
