This paper discusses the dynamic modeling and vibration analysis of transmission lines with Stockbridge dampers. Stockbridge dampers are attached to transmission lines to reduce the vibration amplitude of the transmission line, thus avoiding the risk of fatigue on the line. To build a dynamic model, the kinetic and potential energies of a transmission line with Stockbridge dampers were derived using the assumed mode method and Lagrange’s equation. The equations of motion are expressed in matrix form, which is suitable for numerical simulations. The efficiency of Stockbridge dampers on the vibration reduction of the transmission line was numerically investigated by changing their positions and properties. The numerical results show that attachment positions suggested by the installation manual do not provide good performance; therefore, it requires more investigation. It is also shown that a high natural frequency and damping ratio lead to better performance with regard to vibration suppression.
