A "power blink" is when your lights appear to flicker for just a split second up to a few seconds. Power blinks occur when an object, such as a tree limb, comes into contact with a power line or other equipment. To prevent an extended outage, damage to the line, or your home, a "recloser" will sense a change in current caused by the obstruction and briefly interrupt electricity up to a second or two to clear the fault current. This is a normal safety feature designed for an electrical distribution system, and there is no need to report power blinks. There is no need to report power blinks.
Occasionally during an outage, your power may temporarily go out after being restored. In these situations, it usually means linemen are working on a power line or other electrical equipment in order to restore power to other members.
