Q: Why do my lights occasionally blink?

A: Have you ever seen your lights blink during a thunderstorm? Or perhaps you’ve noticed a blinking microwave clock when you arrive home. These are signs there’s probably been a brief disruption to your electric service.

Momentary power interruptions or “blinks” are most often caused by uncontrollable circumstances. Wind, trees, lightning, birds, animals, equipment failure and humans can all disrupt the normal flow of electricity.

While blinks can be annoying, they show that the electrical system is working exactly as designed. A blink indicates one of Walton EMC’s system protection devices has momentarily interrupted power to protect an entire section of the system. These devices and blinks protect your home, appliances and electronic components – as well as those of your neighbors.

Walton EMC customer-owners should use an uninterruptible power supply (UPS) device to protect computers and other sensitive electronic equipment from potential damage caused by blinks. Also, notify the co-op if blinking repeatedly occurs so the problem can be investigated.
