Just a thought before you get in too deep--what type of breaker panel do you have? If you have Zinsco/Sylvania or Federal Pacific service panel, you likely have arcing bus bars.
Also, you're going to need to correlate any 'events' to the actual flickering otherwise you'll just have a lot of data that you don't know is relevant to the issue. Your LED/dimmer combo may be sensitive to certain things, but not others. I've seen flickering LED issues many times and it has never been a PQ issue, at least not an electric company power issue.
Good call :-) Yes, when we moved in 8 months ago the first thing we did was replace the Zinsco meter panel. I have done that after moving into my last two homes.
Zinsco is well known for burning houses down. In fact, during Escrow, any half-way decent home inspector will flag a Zinsco meter panel as "needing replacement".
To all the other responders, thanks. It's not just the dimmer and flickering issue. We get a fair number of cycle drops that cause my UPS to start up.
We also get a fair number of sags. I suspect that somewhere within a mile of my home is some VERY aged power pole equipment that is starting to arc, corrode,
or fail. The engineer side of me is curious to look at some data, and see 24 hour counts and disturbance types. After that, I can decide if I first call my electrician
or my utility. (I also need to speak to my neighbors and see if it is just my home. I did already pull the covers off the meter panel, and my garage sub-panel, and
torqued down all breakers and busbar connections.)
And @TauTech: Yes, I do have a 1000 series scope and do intend to unpack it from the move, and hook in a 6 volt AC step-down/isolation transformer so I can
easily and safely scope the line and see how clean or dirty the power looks. But for fun, I also ordered the PowerTronics PQR D50 mentioned above. It will be
here Monday.
Thanks,
