As winter approaches in Indiana, Hendricks Power members may experience storms bringing strong winds, snow, and ice. These conditions can affect power lines in several ways, including a phenomenon known as “galloping.”
Galloping occurs when ice builds up unevenly on a power line, creating a shape similar to an airplane wing. When strong winds blow across the ice-covered line, they can cause it to lift, sway, and bounce dramatically.
This movement can damage power lines and electrical equipment, cause power outages, and even break cross-arms or bring lines down. If power lines touch during a galloping event, members may notice flickering lights or see a brief flash.
Some power lines are equipped with devices designed to reduce galloping by disrupting the effects of wind. However, once galloping begins, there is little that can be done to stop the movement until wind conditions improve.
Stay Safe Around Power Lines
If you see power lines swaying or moving dangerously, keep your distance and warn others to stay away. Contact Hendricks Power to report the situation.
Never approach a downed or damaged power line, even if it is not sparking. A line may still be energized and pose a serious safety risk. Snow can also hide downed lines, making them difficult to see.
If you see a downed power line or damaged electrical equipment, stay far away and report its location to Hendricks Power immediately.
As winter weather approaches, understanding the effects of ice and wind can help you recognize potential hazards and stay safe throughout the season.
