Any have pointers to a gadget that will monitor and log power outages
> or glitches on 110V or 220V residential electrical service?
Many years ago the electric company put a test unit on our line in response to our complaints. The unit drew a big graph of the power supply. The test confirmed our complaint was valid and the improved the service.
As others mentioned, you could find such a device commercially.
A secondary question is what will you do with the information?
Since power deregulation (another stupid idea), power companies are not as responsive to service quality. Many have cut back. Having a log of repeated power outages may be meaningless. I strongly doubt temporary transient outages -- enough to cause clocks to go blink -- will be of any concern.
As others mentioned, if you are running critical electronic equipment of any kind, you must have UPS as well as good surge protection. [Hmm, I sound like a high school gym teacher telling the guys to always wear their ...] but the principle is true -- be protected.
I think every household should have one of those flashlights that plug into an outlet and go on in a power failure. Candles cause fires.
