Testing for Dirty Electrical Power


Hi,

Is there any suggestion on a device that can test for Dirty Electrical Power?

One that I have come across is the, "Greenwave Broadband EMI Dirty Electricity Meter" on amazon.

I wanted to see (if it's really even possible) how my electricity is doing and then using the same device on my power strip (Isotek Evo 3 Sirius) to see if there is any change or if I end up getting any other type power filtration in the future, I would want to see how much better or worse that is making everything, besides just audible differences.

If my thinking is incorrect, please let me know.

I'm just curious to see if a device could tell me.

Thanks

@bmontani and @jmkrajnik, regarding Power Regeneration, you're referring to a device similar to what PS Audio sells, for example?

I just looked up that piece of equipment.  Yes, that would work.  Probably better if all the extra bells and whistles help.

The one I have is spec'd for 120 V +-5%, which would be 6 volts up or down.  The thing I think that really helps is the 60 Hz is +-1%.  Cycles/second is really critical for timed motorized equipment such as turntables and tape players, though it is best if everything is plugged into the unit.

There is also a real time display for voltage on the unit.  When I went to get the specs. out of the instruction manual, the line showed 120 V.  Usually, that indicator shows between 116 and 119 volts.  Per the specs, voltage regeneration would not occur until you hit 114 V.  That shows that my assumption about Hz is probably correct.

I just browsed the PS Audio manual.  It is rather sophisticated piece of equipment, and it has a virtual oscilloscope built in (a little bit of evidence that my assumption that only an oscilloscope would help with readings.) It has a built in degaussing function, which is helpful.  Though I have a manual unit from The Gryphon.  That cost me under $100, though I did buy it 30 years ago.

The PS Audio unit is a lot more sophisticated that what I have.  There were options to adjust the sine wave, which of course, would affect Hz (hertz is really sinewave/second).  Mine keeps it stable.  That one allows adjustments based on inputs for further optimization.

Since I've never seen (or heard) a PS Audio unit, I don't know if that extra sophistication would help.  Though having the oscilloscope and the degausser built in is nice.  I think it would be better, but how much?  No idea.

I have a P20.  It is an excellent power regenerator.  Very. Very low impedance.  It is like upgrading the power supplies of all of you components.  

So I bought the Entech Powerline Noise Analyzer and it came yesterday. It has a speaker and a LCD screen.  The instructions are simple. Plug it into an outlet and set the noise level to 100. Than plug it into your power conditioner. So the meter is plugged in and set @ 100, then I plug it into my audience AR6 power conditioner and the noise dropped dramatically, but not entirely. But the number only dropped from 100 to 90, not 0.09!

Hmmmmm

I bought an Entech noise analyzer and found it to be a waste.  Showed basically same results wherever it was plugged into.  Power conditioners, wall, wall with appliance running etc.  Sold it on ebay the next day
