Does the "Power-Save" work?


I saw a commercial last night for this "power-save" unit you connect to your power system that functions as a filter, surge protector and saves energy for the whole house. Has anyone out there ever dealt with this or used one?

Bull*** in my opinion. There is no way to filter and recycle the unused power from appliances. The last two claims about reducing noise and eliminating spikes could be true.

Looking over there website, it claims it saves you money by correcting the power factor(that is what I got from it). I do agree this works, but how much does that factor into a house. I can't think of to many motors in my house, maybe 2 or 3 and they probably don't draw much current. Just my two sense, somebody with more smarts about this can give you a better answer.

If you want get power for free you don't want to correct the power factor. You want to throw it as far off from unity as possible that is where you get the free power.

changing power factor does not change KVA.

Since your meter measures KWH which is KVA X Hour. This can have no effect on your bill.

KVA and KW are not equivalent in AC circuits. If you go away from unity power factor KVA is higher than KW by a ratio related to the power factor. Unless you have some sort of special meter you are billed on KW not KVA.

I'm an electrician and the principle is sound butt not the way they do it.
Capacitors like the one in the unit will correct power factor in motors and reduce the amount of watts used to make your motors run more efficiently, and save you money....butt the capacitor must be sized properly.You would need a Watt meter to tell you the motors true power and compare it to the current being drawn from the unit, and then about 5 more formulas to go through to get the right capacitor to make the motor at most 95% effcient.
