It’s winter in Indiana. That means storms with wind, snow and ice. When high winds and ice combine, it can affect power lines in a unique way causing them to “gallop.”

When ice accumulates on power lines, it forms a teardrop shape. If there are strong winds, the ice that builds up is only on one side of the power line, taking on the shape of an aerodynamic airplane wing, which results in the line lifting. This is known as “galloping.” 

When this disproportionate buildup occurs, it changes the flow of air around the line, which causes it to start the galloping movement. Galloping can potentially damage the lines, cause power outages and even cause cross-arms to break, bringing lines to the ground. When galloping causes the lines to touch, you might see a small flash or the lights in your home might blink. 

Once galloping starts, there isn’t much that can be done to alleviate the issue until the winds stop. This is why many power lines have objects, such as twisted wire or round or angular pieces of metal, attached to lines. These devices are placed on the power lines to help reduce the potential for lines to gallop. 

If you encounter power lines that are swaying or bucking dangerously, stay away, warn others to stay away and contact your electric cooperative as soon as possible. Remember, snow can hide dangerous, downed lines, especially if the lines are sagging and the cross arms are broken. 

It is important to keep your distance from these downed power lines no matter the season. When you see a power line out of place, Clark County REMC reminds you to never touch it; never approach it. The result could be deadly! The best course of action is to steer clear and call for assistance.

If you see galloping power lines:

• Keep your distance — ice can break off or power lines can break loose.
• Contact Clark County REMC to let us know of the potential damage as soon as possible.

If you see a downed line:

• Stay far away and warn others to stay away.
• Remember, a downed line can remain energized even if it is not sparking or arcing.
• Always report the location of a downed power line and damaged electrical equipment to your electric cooperative.
