According to my PS-Audio Power Plant, my incoming AC at my audio system (Portland, OR) is typically119.5-119.7 VAC with 2.2% to 2.3% THD.
Best place to live for good quality power
For those of you who have traveled around the world with your hi-fi, what have you learned about where to live for the best power?
- Dense city but right near a substation
- Or far from a substation is ok, as long as few houses on the grid (rural)?
Etc
Some of you are into batteries, but lets talk about how location affects power.
thanks in advance

@jaytor Thanks for sharing your data. I too have a PS Audio power plant and enjoy the built in oscilloscope. I've checked my data occasionally over several years and it is always around 4.2% THD. voltage can vary from 114 to 123. I set the output to 119.5 and get .1% thd. Here is a link to the chopped sine waves of my input (same as I posted above). https://photos.app.goo.gl/5scsFGHBRjE8ewti9 California electrical grid is not the best managed. Of course, except for audiophile equipment, nobody really cares. Your hair dryer or stove will not notice the difference. Jerry |
@carlsbad2 - I live less than 1/2 mi from our electrical substation which may help explain the more consistent voltage and lower THD. I don't think there are any manufacturing operations (which tend to operate large motors) very close to me. I don't think I've ever seen the voltage less than 119 or more than 120.5, so it stays pretty consistent. I also have solar panels with an inverter connected to the grid. Not sure if that helps or hurts. I have my power plant set for minimum THD, so my output voltage is a touch higher at 121V, but also with 0.1% THD (this is probably the lowest it will report). |
