AC powerfactor correction to save money

#1 · date not recorded

Hi,

Here the start of a off topic subject.
However, we all might save us lots of money, which we then can use for our waterfuel projects...

In this video you hear the man talking about not being able to save money, but is he correct?
His amps drop. his volts drop, so in my opinion, his powermeter should drop as well.....

What are your thought on this?

I have been wondering about that my self, and planing to test it out.

here is my plan:

use my existing PF meter and check the power factor of an inductive load like a motor.

then turn off the power for the entire house. and power the motor only.

use a stop watch and check how long it takes for the electric meter to complete one turn.

then correct the power factor and check the electric meter again.

from what I read about PF, it can only be adjusted on inductive loads.

As far as i know you only pay for the real power at the plug anyway. the energy stored in inductive/capacitive elements isn't lost anyway and and recycled fully.

Same here.
Just run some tests on it.
If my meter is slowing down when i corrected the powerfactor, then we have a point, is it.

Does anybody know the difference between the digital meters and the old "wheel" meters?

160uF cap to correct the power factor on your waschinemachine......

Hmmmm,

Maybe i have to correct the powerfactor on my variac.....
Then i will be sure come closer to having a closed selfsustaining generator on HHO.

In a purely resistive circuit, all circuit power is dissipated by the resistor(s). Voltage and current are in phase with each other.
In a purely reactive circuit, no circuit power is dissipated by the load(s). Rather, power is alternately absorbed from and returned to the AC source. Voltage and current are 90o out of phase with each other.
In a circuit consisting of resistance and reactance mixed, there will be more power dissipated by the load(s) than returned, but some power will definitely be dissipated and some will merely be absorbed and returned. Voltage and current in such a circuit will be out of phase by a value somewhere between 0o and 90o.

This correction, of course, will not change the amount of true power consumed by the load, but it will result in a substantial reduction of apparent power, and of the total current drawn from the 240 Volt source.
