Thread: ...So WTF happened?

Thanks for the advice.

I did check things out and they are all normal now - voltage, wave form and phase. (I didn't hook up my frequency counter, but can't imagine that could change as it is controlled at the source, whereas everything else can be influenced by faulty transformers, inductors, etc.)

What I THINK happened was a voltage spike either when the power went down or came back up. The only way this would trip anything is if the result was shorts that would carry things over the top of the current levels of the breakers. Another possibility is an "inductive kick", if a quick spike went through all the appliances and everything and then just quit again. Remember that breakers are current sensitive, and higher voltages result in lower current. We have no over-voltage protection, but there are multiple levels of circuit breakers from the master on down to the sub-circuits.

No - everything seems to be back to normal now. It was just a really bizarre thing to have happen - especially after hearing about O's situation.
