AC powerfactor correction to save money
« on: April 25, 2010, 16:42:49 pm »
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... ;D

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?

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.
