Modification of a stockbridge damper: a review

Abstract

Overhead power cables get exposed to wind motions that eventually cause oscillation and significant fatigue failure to them. Aeolian vibration is one of the most common vibrations caused by high frequency and low amplitude. Although other wind motion vibrations cause fatigue failures on transmission lines, Aeolian vibrations account for a greater percentage of these fatigue failures. Various devices have been developed, designed, and implemented to minimise vibrations on power lines. The Stockbridge damper is one of the standard dampers that is used. The fundamental understanding of the asymmetric Stockbridge damper is studied in this review paper. The focus is on the mechanism of the damper, resonance frequencies, and amplitudes of vibrations. The review will also focus on the developments made to increase the efficiency of the Stockbridge damper.
