What is the primary impact of Aeolian vibration on line conductors?

Aeolian vibration refers to the oscillating movement caused by wind passing over fixed structures, such as overhead power lines. The primary impact of this phenomenon on line conductors is physical stress and potential failure. When the wind causes the conductors to vibrate, it generates repetitive motion that can lead to wear and fatigue in the material over time. This can create issues such as metal fatigue, which may weaken the conductors and increase the risk of breakage or failure.

While other options, like increased conductivity or heat generation, may have their own relevance in electrical contexts, they do not directly correlate with the specific effects caused by Aeolian vibration. The primary concern with Aeolian vibration is indeed the physical stress it places on the line conductors, making this the most appropriate answer. Understanding the implications of such vibrations is crucial for ensuring the durability and reliability of power transmission systems.
