What are aeoline vibrations in overhead transmission line conductors?

Aeoline vibrations, also known as aeolian vibration, refer to the oscillations that occur in overhead transmission line conductors due to wind. These vibrations are caused by the interaction of the wind with the conductors, leading to small amplitude, high-frequency oscillatory motions. They typically occur in overhead lines under steady wind conditions and can result in significant fatigue damage over time if not properly managed. The vibrations can be influenced by factors such as the wind speed, conductor design, spacing, and tension. To mitigate these vibrations, various techniques, such as installing dampers, can be employed to reduce the potential for damage and maintain the integrity of the transmission lines.
