Waross... we appear to be in agreement.
Displacement Power Factor v's Distortion Power Factor:

Quoting Waross:
"In some cases the calculated interest on the cost of the PFC may be greater than the saving in energy cost."
Many PFC users claim that the savings are ~1/3 of the power bill.
Given the potential metering error that claim sounds reasonable.
PFC (or some other method of...
Responding to 3D Dave on the Hall effect:
Quote from the article:
"A deviation of +276 % was measured with one static energy meter,
+265% with a second and -46% with a third static energy meter.
After dismantling it was revealed that the meters with the positive
deviation used a Rogowski coil...

"A small capacitor is often enough to attenuate the very high frequency spikes."
A long time ago (as a kid) an electrician told me to fit a capacitor to stop the crackle and pop on the TV and static on the radio.
It didn't seem to make much difference.
Years later after...

"There are probably a large number of devices that can limit the transmission of noise to the power meters; if you want to, go ahead and buy a PFC system and install it..."
Dave is right... any device that limits the transmission of noise should work.
It doesn't have to be a PFC...
Did anyone read the full IEEE article or just the story about the article (the IEEE reference was included in the article)?
