Simple,cheap,working,legal device to reduce electric bill(power factor optim.)

@all
first its a watt hour meter it reads watts not volt amps.,residential users are not billed for phase angle.
second the meter has a coil for each leg so an imbalance in current dose not make an improper bill.
what were you going to do sit there and juggle ccts everytime something turns off  or on?

@ all

If you want to save some Money, then first of all, reduce the need of electricity as much as you can.
This migt be done by using smaller Lams or LED bulbs.
Another way is, to use Timers to cut the time, that some Devices, like Chargers, are on the grid.

On another Place i had made some calkulation and like to reply it here .

Lets do some analysis to see the facts.

Lets assume, one have a small Heater for the bedroom.
Tle label shows. 220V, 55Ohm for the value of the resistor.
Fact is: the Resistor does in a normal environment NOT change his properties.

If the Heater is connectet to the Grid, he takes P=U*I  880Watt
I=U/R  220/55 = 4  Amps    The Power of 880W/h will be charged on your bill.

Now the situation changes without you know.(perhaps)

The Energy supplier encreases the Voltage in his Grid to about 250Volt.
Your Heater in the Bedroom and other Resistors on the Net behave as usual.
But this causes different effects.
Now I=U/R   is   250/55= 4,563 Amps  And the Heater reacts with more Power.
P=U*I = 250 * 4,563 = 1140,75 Watt
What does it mean?
The charge on your Bill encreases by more or less 22%

Without you notest.

"Start of the  joke"
So in this case it might be of use to have a small resistor in spare 16Ohm might be fine,
but this must be able to carry the load of 1140Watt.
"End of joke"
Result:
Actions on both sides of the Meter effects the other side.

The biggest save effect is based on the Voltage.
The correction on the Power faktor workes  for inductive loads only.
Inductive loads are from coils. Transformers, Motors and so on.

The cos/phi power factor on a meter is Zero, when there is no load connected.
As soon as one connect a inductive load ,on the plug in your home, one
pay for the reactive power too.
The usual meter das not include a circuit,that corrects the power factor.

During the night, if some electricity supplier, increase the voltage on the grid,it directly
encreases the amps, that all resistors take from the net.
This includes all non inductive resistors too. ( Heaters)
You have to pay for it without beein asked.

Give it a proove yourselve by just see the formula to calculate the electrical Power
and as well as to calculate the powerfactor.
The Voltage is a Key on all calculation.

I have ordered some of the power factor corrector devices.
As soon as they arrive, i will build a setup to test and proove about the actual
advantage that one can expect.

fritznien, 

I'm sorry if you may be confused, as a electrical engineer for 10 years 24 years ago, and a practicing Oregon State licensed electrical contractor for the past 24 years, with 34 years of electrical experience total, one would think I know something about this having delt with it 100's of times. 

Amps are Amps and have nothing to do with "PHASE ANGLE" in this post, or a residential service.

Do you know how to change the "Phase Angle" from the power supplied to a home service by the utility provider without effecting other services supplied from the same transformer? or can you ever do it with out permission from your utility provider?

Adding PF corrector equipment can effect every service connected to a "shared" utility service providers transformer and can cause fluctuations to all services connected to that transformer.
