The thing is, I have seen small boxes sold here, small as... 3 cigaret packages? that claim to lower your power bill. I have seen them, but I had no permission to disassemble and find out what they do.
The assumption is that they are power factor corrector boxes for homes.
Before you can correct, you have to know whether the load is overall capacitive or inductive and by how much
The second assumption is that the home meters are imperfect, and measure rather current than actual wattage.
They measure power and must be accurate enough to be legal for trade.
Thus the boxes would lower the actual current flow, with a power factor closer to 1, or 1.
If this is not so, I have no idea what these gadgets do. :-?
There are motor controllers that vary the voltage to a motor. By lowering it, the power factor is reduced. On the other hand, the main purpose of those boxes might be to lighten your wallet. There have been a lot of scams over the years. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
