Don’t you just hate those blinking “12:00” clocks? Manufacturers could build in a backup system to avoid this, but that would increase the cost and you may not want to pay the extra amount for the device.
The blinking is often set into motion by the cooperative’s line safety devices used to avoid frequent and prolonged outages. The devices are called oil circuit reclosers. They operate by opening the circuit for an instant when the line is contacted by an object such as a squirrel, racoon, tree limb blowing in the breeze, etcetera. The object usually frees the line on the first blink. If not, the recloser will operate two more times. If the line is still not clear, the device will shut down the power until a serviceman clears the line and closes the oil reclosers.
Thus, the safety devices either avoid outages or shorten the outage time and decrease the area affected. They also prevent damage to the line, which is another way of keeping electricity at the lowest possible cost. When the clocks blink 12:00, keep in mind the manufacturer is trying to save you money, and we are trying to provide you dependable service at the lowest possible cost.
