Reactive Generator Research for everyone to share

[geenee]

Reactive power don't make alternator(generator) slow down or consume.but power company tell you if you make reactive power that make heat to the wire or more load to generator.why??power company liar for making more money.if all of us use Reactive power then power company lose more money(because low watts consumption).

Luc shown very clear,i don't understand why someone can't understand it??

Yes, that is what Luc tries to show using Power Factor of ZERO = 90 degrees phase shift to
generate REAL POWER of 20 Watts in his light bulbs as the second video

https://www.youtube.com/watch?v=byJ0Qo10g3o
shows.

Well, here is my analysis of this second video:

1. First it would be nice, if Luc could provide his setting on his scope for the Math function,
so we can see, what excatly is multiplicated there and with what scale...

Also he made a small error when explaining the red Math function trace at :

min 2:32 where he said amps, but it must be Volts x Amps= Watts.


I have to go out now.

Will be back later...

Yes, it is Volts X Amps. But what is important here is a perfect 90 degrees phase shift which = Zero Watts in

Please note that this is not just a conventional transformer circuit.

It is a High Impedance Secondary (short circuited) with a tuned Series Cap (around 48uf for 120vac MOT or 24uf 220vac MOT) on one leg of the Low Impedance Primary with a Series Resistive Load (bulbs about 10 ohms lit) on the other leg of the primary.

Hi Luc,
well, please provide data, what your scope is exactly doing at the Math trace and what kind
of factors you did put in there ...

Also this second video has the same analysis as your first video.

It could be just a Impedance matching in the Reactive power input where the
REAL power stays constant.

So you really need to have at the input of your drive motor a measurement unit that can display
both Reactive power input and Real Power input.

Maybe you can do this via your scope by using 2 Math functions ?

As your digital input Watt meter only shows Real Power input and not Reactive power
input you really need 2 power meters there or use your scope to show it via 2 Math functions.

Then you can see, if you draw these 20 Watts at the light bulbs, if your Grid input power into the
drive motor will also increase for 20 Watts in the Reactive power input or if the relationship
of Reactive to Real power input will change for 20 Watts...

So you really need to see both power inputs in realtime at the drive motor input to make a final decision...

Hope you can do this via your scope, that would be the easiest way and better try to use a 1 Ohm shunt resistor
otherwise you need to multiply all your current values by 10 as it was the case in the posted 2 videos.
(For easier reading purposes)

Hope this helps.

Regards, Stefan.

Stefan,

The electric motor turning the generator head is not working on reactive power. So why would you need to check its phase, power and so on. It is connected directly to the 120vac grid, so the plug in grid power meter is quite capable of displaying how many watts it uses since it takes "normal" power factor into consideration.

You are either misunderstanding the DUT in the video or I don't understand how my circuit (connected to gen head) can have an Impedance match to the motor (connected to grid).
