A flicker or blink is usually caused by a temporary fault on the distribution line. CTEC installs specialized equipment on distribution lines that causes the line to blink to avoid a long-term outage or damage. Typical examples of this are when a tree makes contact with a line temporarily, lightning strikes a pole, or an animal makes contact with energized lines. The special equipment will sense the fault, temporarily de-energize the line so that the fault condition can clear, and then re-energize the line to see if the fault has cleared. When this happens, the consumer experiences a blink.
