Brief, momentary outages that were unnoticed years ago are "reported" today by the many electronic devices around us. Before digital clocks we probably didn't notice most of these "blinks."
Many times, having the power blink is better than the alternative — having it go out completely. Blinks are sometimes caused by reclosers, which are devices designed to protect the electrical system. Reclosers essentially act like the circuit breakers in your home, with one major difference. They reset themselves after "breaking" the circuit.
The intent is that a tree touching the line, or other problem, will cause the recloser to open. The device will reset itself and power once again will flow down the line. If the problem has cleared the line, power will stay on. If the problem still exists, the recloser will operate again. After trying three times, most reclosers are designed to stay open until the problem is fixed and the device is manually reset.
The opening and closing of the recloser is almost instantaneous and is often not even noticed. The alternative to using reclosers is to use fuses on each line. While greater use of fuses would result in fewer blinks, it would also create more outages.
PEC is constantly evaluating our power lines to identify potential blink-causing problems so we can take preventative measures. While we may not be able to prevent all blinks, please let us know if your home or business experiences an excessive number of them.
