Distortion on the Power Line

@cleeds

Don’t disagree but it seems like instead of guessing about all your neighbor’s potential sources that the best thing would be to do a process of elimination within your own home. Just seems odd all these random guesses about issues outside your home that aren’t actionable.

The best thing would be to determine if it is your own home our outside ... hence the 0 cost, quick method of figuring it out I described above. If you determine its outside your house you may have a remedy with the power company so yes it is actionable.

greetings! I believe any good quality power amp with a regulated power supply should pretty much make AC line distortion a non-issue...
don't you think the average high quality loudspeaker produces 10-15% distortion below 100 hertz/95 decibels anyways...?

jea48,

If you don't have one, you can pick up used Fluke 43/43B for < $1,000 used on EBAY which is fine for single-phase use. The Fluke 41B is an older unit, but ones in good condition go for <$500 regularly with required accessories. There is even one with a 1 year warranty for $550. They come standard with 1000:1 current probes with BNC connectors. I have hooked up a 10:1 current probe and used one for low power measurement as well.


The 3 phase units are pricey even used.
