Stockbridge dampers are devices used to reduce vibration and prevent damage to overhead power lines caused by wind-induced oscillations. They are named after their inventor, George H. Stockbridge, who patented the device in 1921.
A stock bridge damper consists of a weight suspended by a cable or rod attached to the power line. The weight oscillates out of phase with the power line, creating a counterbalancing force that reduces the amplitude of the power line's vibration. The damper's weight is carefully chosen to match the frequency of the line's vibration to maximize its effectiveness.
Stockbridge dampers are commonly used in transmission and distribution lines that are subject to high wind speeds or spanning long distances. The dampers are installed periodically along the power line to prevent the build-up of high-amplitude vibration that can lead to damage or failure of the line.
