Blinks
What causes blinking lights?
Blinking lights are actually a sign of a properly functioning distribution system. If a fault occurs on a line (this could be from a lightning strike, trees limbs coming in contact with a line or even an animal), a device called an Oil Circuit Recloser (OCR) opens to stop it and then closes again.
In this way OCRs are essentially "circuit breakers" for the distribution system, much like the breakers in your home’s electrical panel. It permits power to continue flowing with only a brief interruption rather than an extended outage.
Typically, the OCR will open and close three times to give the fault a chance to clear itself. If the fault does not clear itself after the third "blink," the OCR stays open, causing an outage. This protects the lines from damage and isolates the problem until linemen can repair it.
While these blinks are a sign of a properly-functioning distribution system, they can be annoying. Electronics with digital clocks need to be reset and computers can shut down, etc. Members can help counteract these effects by purchasing appliances with battery backups. Surge protectors for lightning strikes or regulator malfunctions or uninterruptible power suppliers (UPS) for low voltage or loss of power are also recommended for critical devices.
Meanwhile, your electric cooperative is also working to keep blinking lights to a minimum. Tree trimmers are hired to keep power lines free of interfering branches. Pest shields are installed to keep animals away from sensitive equipment. Lightning arrestors are also part of the process Federated uses to make sure members have a reliable system.
If you are experiencing blinks often, please call us so line crews can inspect the lines and equipment. Otherwise, e-mail us. It's also helpful if you can tell us the days and times the blinks occur.
