"Blinking" electrical supply
Years ago, a thunderstorm would either leave us with electricity or without electricity.
In the case of Friday's storm -- the fiercest winds I've seen -- the power company dimmed our power down to about 25%, then restored it, then "blinked" it bright-dim-bright-dim-bright-dim — just like a turn signal in an automobile. (About 30 seconds).
At the first dim, the refrigerator sounded labored, so I unplugged it. Then went around and unplugged the rest of the motorized and electronic appliances.
Isn't irregular electrical supply bad for motorized appliances -- like the refrigerator and water pump? Or are they internally protected against power fluctuations?
Did anybody experience any appliance failures due to the above "blinking"?
