Power Line Mystery

A

Guest
My computer is connected to a UPS. The power in my area is very stable
and the UPS has activated successsfully maybe once or twice in the last
two years. But, daily, at around 9:15 AM it beeps about 4 times. I don't
notice any flicker in the lights. Then again, my light at my computer
table runs off a second UPS, which, by the way, does not beep. Oh, and
the computer is not the culprit as I have a new one connected to the
offending UPS.

I imagine that somewhere a big machine on my power grid is turning or or
off. It certainly doens't coincide with any electrical events in my
house.

Anyone have similar occurances? I may hook up some kind of signal
conditioner to my power line and try to capture the glitches. I don't
want to buy anything, but would like to build something. Anyone have
access to links to schematics for such an instrument?

Perhaps you could put a voltage meter on the line and see what
is happening. A multimeter will do the trick, as will a specialized
AC line voltage meter that you can get inexpensively at places like
Radio Shack. Finally, if you really want to see this through, call
the power company--they have professional meters that they can hook
to your line.

I once lived in Duluth, Minnesota, in the downtown area. Everytime
the big lift bridge opened, my ancient (but then new) Macintosh would
power cycle or crash. UPS's were relatively unknown back then, and
as a student, that was out of the question. But it was pretty obvious
when the bridge was going to open with all the boat horns and such.
I'd simply shutdown, or save often. I did lose a lot of lightbulbs
in that apartment.

It is not necessarily the power grid that make the UPS beep. It also may be
a message from the UPS for instance to alarm you to replace the batteries.
You should find a description in your manual.

Some models will start to beep once in a while to remind the operator that
the batteries are weak, and will soon have to be changed. The battery
lifespan is about 3 to 4 years on the average.

OK, but why only once a day. You may be out then, like at work, and
never get the message. At any rate, the batteries are new.

You should consult your user guide. From my experience, after a number of
years, the batteries start to go down. This is normal. We have a fair number
of UPS's where I work. When we start hearing them beep once in a while, it
starts to get more frequency over the months. As soon as we hear them doing
this, we change the batteries.

The above applies if you know for sure that the power going in is stable.
You will eventually know when the batteries are not working any more,
because the UPS's (depending on the model) will not start, and during power
bumps they will no longer do their protection work.

OK, I ran the self test and it was OK. Its a UPS Smart 600.

In my lab at work, when the machines in the factory would shut down
before quitting time at 4PM, the electrical noise was bad enough on the
lines that we could not do some tests. We even experimented with hugh
isolation transformers for the lab benches, but NO-GO. We just learned
to live with it and avoid start-up and quitting times for critical tests.

Down the street for me is a factory that builds microwave wave guides.
Maybe they are the culprits. Its not a problem other than I would like
to know the reason for the beeps at ~9:15AM.

I'll have to come up with some kind of recording monitor.

Since it is repeating and predictable, your power might be sagging at the
same time every day due to some significant load coming on line (a factory,
for example). Since your table light is on a UPS, you might be missing the
"brown-out."
