The control of overhead transmission lines vibrations is achieved by Stockbridge dampers. However, the effectiveness of the damper is significantly dependent on its location on the conductor. This paper studies the arrangement of Stockbridge dampers on power lines vibrations using both analytical and experimental approaches. An explicit expression of the loop length is presented for the first time. This expression is used to determine the optimal damper location based on a rational approach. The effectiveness of the proposed approach is validated numerically and experimentally. The results show very good agreement and indicate that Stockbridge dampers are more effective for asymmetrical damping arrangement with the bigger counterweight oriented toward the tower.
