Power Line Quality Monitor that does not cost a fortune

(1/5) > >>

nealix:
I am looking to find a residential single-phase plug-in power line quality monitor that
does not cost $4000 to $7500 like Fluke or other industrial stuff.   Does anyone know
of any lower cost (under $600) units that can monitor/log spikes, noise, surges, sags,
and other basic disturbances?    We have repeated flickering of lights, and I want to
be able to show actual data before calling the power company or paying an electrician.
Most of the flickering is on circuits with light dimmers  (Lutron Diva), and all is with LED
lighting.  Yes, I know that these two are most sensitive to power line disturbances, and
I am interested in learning more about the power quality and how many "hits" per hour
are happening.

So far, most loggers or monitors that I find under $1500 are only logging/recording
voltage at several samples per minute, and not spikes, harmonics, noise, etc.

Any ideas?

Many LED SMPS are not dimmable and/or if not loaded correctly will flicker.
You sparkie should know all about this sort of stuff.

Even most LED lamps which are sold as dimmable have significant parts of their operating envelope where they flicker.

Thanks guys, well aware of all this about LED lighting.    The original post still stands as a question.
Does anyone know of AC Power Quality Monitor / Logger that does not cost a fortune?

Thanks,

Neal

Neal,
I have a Powertronics D3000 monitor that may work for your purpose that I would sell cheap.  I have the manual also.  There are a couple of these on flea-bay if you want a picture of one.  PM me if you are interested.
