WebMar 1, 2024 · When ice accumulates on power lines and the wind blows simultaneously, the wires can start to move up and down in an oscillating motion called galloping. Galloping can cause wires to slap together, resulting in a fault or subsequent outage. The increased movement can also cause crossarms to break, bringing power lines down. To … WebPosted: 12.08.2024. When Ice storms coat power lines, high winds can lead to lines that bounce and buck around. While rare, this movement is known as "galloping lines". Power lines are designed to sway, but if a wire is weighted down with ice and is pushed around from wind it could move close to a grounded component or an energized conductor ...
