Just my observation, but I was under the impression that power factor compensation with the power companies is primarily capacitive. In other words, the power grid out to the public *appears* overly inductive and power companies compensate this by adding capacitors. I'm not sure in light of this how lowering the line voltage would gain much of anything. As has been said, if the public grid was primarily resistive, I think you'd get away with lowering the voltage to lower power.
Just a personal comment - I think I'd like to see a discussion on 240vac being the household voltage rather than 120vac for power conservation. Some of the high currents from 120vac I've personally seen causing even slight heating of power cords seems to be a waste. Double the voltage, halve the current, thus I^2R loss in power cables alone reduce by a 1/4. That's a lot of power cables we're talking about. Just my two cents. - Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
