Why does my power blink?
Blinking lights can be a result of momentary outages that occur when some type of disturbance exists on the line. They most often occur when tree limbs or animals come in contact with electric lines, or when lightning strikes.
When lights blink, it can be an indication that the cooperative’s equipment is operating properly. If a fault or short circuit occurs on a power line, a device called an oil circuit recloser (OCR) opens to stop it, and then quickly closes. Although the process is quick – and usually temporary – it may cause your lights to blink, making it necessary to reset digital clocks and appliances with digital displays.
The OCR is essentially a breaker, functioning much like a breaker in the electrical panel in your home. It permits power to continue flowing through the line with only a brief interruption of service, rather than causing an extended power outage.
If the short circuit continues, the OCR will operate or trip three times before eventually stopping the flow of electricity and causing a power outage. This process prevents serious and costly damage to our equipment and lengthy outages for our members, cutting off power to a section of the line and isolating the problem until it can be repaired and service restored.
Although the weather and nature’s creatures are beyond our control, Beltrami Electric takes all possible measures to prevent these occurrences and minimizes the effects to our members. Members can lessen the effects and inconvenience of “blinks” when they occur by purchasing small appliances and digital clocks with battery backup. Other ways include installing meter-base surge protection for the major appliances in your home and surge protection with built-in uninterrupted power supply (UPS) for your computer or other electronic devices whose memory would be lost with a power interruption.
