Looking at a newstyle digital power meter there appears to be 2 power consumption measurements.
One reading appears to be tracking high power factor consumption when VAs are 20% higher than watts and the other reading appears to be billing just regular wattage.
I am sure power consumption at less than 0.80pf comes with a nice penalty. I would like to live in the same town where everyone has this meter.
So the mig welding machine is running well above 0.80pf, up to .95, but I have 2 problem air compressors, one runs a .7pf after some minor power factor correction (I added a salvaged 8uf oil filled motor run capcitor) and i have another compressor that runs a .44pf.
