can we measure noise on power lines?
Can we get meaningful measurements of power line noise? Is the noise too low-level to measure without exorbitantly expensive equipment? What equipment is required? Outside of laboratories, who has it?
We buy all sorts of devices to clean up power. Why can't we measure the noise that's there and target it

Hi Lloyd, See my several posts dated 3-19-2014 and 3-20-2014 in this thread. The bottom line being that such measurements may be less useful than might be expected. Regards, -- Al |
Thanks, Al and Hew. back to trial and error, I suppose. I've used a pair of Noisetrapper isolation transformers since the '90's (no longer made), and wondered if there was any way to determine if it's really necessary to seek further improvement. The noise level in my apartment is so high (primarily fountain pumps and a/c units, and traffic), there is little point in seeking the legendary "black background" |
