I saw this on Facebook and it is being offered here in Mexico. Make a long story short, high consumption here transfers into commercial rate charges. It gets hot here, over 100 degrees and humid, similar to Texas.
Anything that can help reduce the electric bill is a good thing. I am just wondering how safe this is to the air conditioning equipment.
Well, who was it that said 'There's sucker born every minute'. But look, I have a devise that will produce power from worn out tires and I am looking for investors. Would you be interested?
Can not watch the video here however.. There used to be a company here in the us that marked something called a Green Plug or Green Power Plug or some such.
What it was was a power factor controller.. Now here is the theory. Which I do understand by the way. (At least part of it).
Since it is not possible for the designer of the motor to know EXACTLY what voltage it will be operated at they tend to "over build" a bit. Also, it is rare (Save for say a refrigerator or like device) for a motor bulider to know the exact power requirement, Thus you figure out what you need and take the next bigger motor off the rack.
The result is that if you hit this motor with the full 120vac.. That's more than it needs, The excess is translated into heat,, and the voltage and current peaks are not exactly in phase with each other (I think voltage normally leads).
In fact.. I have seen installations (With my own eyes) where it was so bad that the motor was drawing current, when voltage was applied, BUT IT WOULD NOT TURN. (NOTE: I worked as night security in that plant, NOT as a technician). A very good friend of mine (At the time) was consulted, took a measurement or two, Dug around in his junk box and got it working by changing the relationship between the voltage and current peaks. (He added capacitance bring the two back into step)
By the way, The power factor (Always 1.0 or less) is, as I recall, the cosine of the angle between voltage and current. Confirmed, it is the cosine.
What the "Green Plug" type devices did was lower the voltage (Well they lowered the time the voltage was turned on) as the effective voltage is lowered the motor tries to keep running the same speed.. (Shunt wound motors that is) and the power factor starts to approach 1.0. This lower voltage does not damage the motor, and when starting (When low voltage does damage) the controller basically takes a break.
This results in the motor running cooler, and wasting less power.. Or so the theory goes.
Now, that said, Some folks insist the KWH meter actually measures WATTS,
Watts (in an ac circuit) are Volts, times Amps, TIMES POWER FACTOR, so though this does indeed save power. if these folks are telling the truth it does not save you money. (Well perhaps cause a cooler motor won't tax the air conditioners as much)
If, however the KWH meter reads volts and amps... (Volt-amp-hours) then .. it saves you money as well.
Which of those two statements is true.. I DO NOT KNOW.
Of course, since I could not see the video, This is all conjecture.
I have tested one power factor controller on a de-humidifier, and it very seriously made a difference. Unit ran much cooler and actually better with the "Green Plug" in line. My test bench could see the difference in current.
I might add, Later I added coolant to the unit, after that the controller did not make as big a difference.. Oh, and it worked even better still.
(This is one of those "Refrigerator like" devices so that is not surprising, in fact it was mentioned in the instruction manual)
Works better on fans and blowers where the load changes as dirt accumulates.
Nothin adds excitment like something that is none of your business

There is a plant in California that does just that and I know a person who made a ton of money investing in it.
