Electrical distribution systems are designed so that blinks will sometimes occur, in lieu of a total loss of power. Most all-electric distribution systems have devices called Oil Circuit Reclosers (OCRs or Breakers). These “breakers” temporarily stop the electric flow when they sense a problem on the line. A typical problem causing a blink is a limb that blows out of a tree and hits the electric line, then falls to the ground. The breaker would make the electricity flicker or "blink" when the limb hit the line. The power comes back on if the limb clears the line and falls away quickly. If not for these breakers the electricity would be off until an electric crew arrived to replace a fuse.
