Whoa, Brown outs is badddd news. I work for a POCO and a brown out is most likely going to be a prelude to an outage. Low voltage will damage equipment in a heck of a hurry and needs to be corrected quickly. As the voltage drops, the current of course rises rapidly to maintain load.
The sound of an air conditioner or refrigerator running under voltage is enough to make me run to unplug/turn it off before the motor smokes.
Modern dispatch systems will warn of these conditions and it has become quite rare (around here anyway) to have a brown out last more than a few seconds.
