Simple to build isolation transformer that consumes less power than it gives out

[wattsup]

  It's refreshing to see someone take suggestions and quickly proceed with actual testing -- thanks, Wattsup.
  Your vid is still processing as I write, but I look forward to viewing it.  Glad you went ahead and got the Kill-A-Watt meter also; it may prove useful as we go forward.

@JouleSeeker

The only real reason I am pursuing this is because of the following reasons;

1) The device for me is a level one device, meaning is uses standard mains plus off the shelf components that can be easily replicated by anyone around the world. This is the ideal OU device (when it works). hehe

2) My TK works have stalled because I am waiting for a circuit to be built for me by a local EEer. He says during this week it should be ready.

I told you so.
Why you wasting my time posting these faulty results.
Taking measurments the correct way is critical otherwise you don't have to do this kind of research and especially don't post results unless you are clear that they are accurate.

@microcontroller

Hmmmmmmmmmmmmm. You are right about that.

Basically this exercise now shows that anyone doing output measurements with a clamp on ammeter where the output is in the single decimal range CANNOT BE TRUSTED. That's the learning part of this. One the other hand, yes, I deserve all the flagellations for not seeing that myself. Sorry again. But imagine all the youtubes out there showing such an output with a clamp meter.

This time you changed setup and variac seems is needed component for effect in your case. It acts as first tuned transformer...
Just leave power meter before variac and everyone will be happy

@T-1000

I put back the Variac. It consumes 0.04 amps and 4 watts on its own, regardless  of the level being from 0 to 120 VAC when no load is applied to the Variac. With the Variac and the system load, there is no change for the better on the DC output. But I still have some good ideas to test today. This is all small play right now until I receive my real isolated transformers.

But at least we can now say that on the AC output, one side of the big bulb is showing low voltage but the other side is showing a very high voltage rather reactive energy output even when loaded with the bulb. Without the bulb one would expect a much higher reactive output. So there is a low level and a high level output on the AC side and maybe the low level side can be used to pass through some other coil, etc, before it goes to load. But in an AC output, should not both sides be the same level since it is always alternating? When measuring for DC voltage, it shows zero.

Maybe @JouleSeeker can expand on that with his device.

Well i don't know what to say.
I did not disable a reply button or anything else so if you are not able to send out a Private Message i wonder who's the idiot.
This makes me think you don't know something about anything.
That must be the reason why you ask idiot questions am i right?

Also, i share too i build and tested the experiment in this topic yesterday, you can see the results on page 6.
kNOWING ISN'T THE SAME AS TESTING, SO SHARING WHAT YOU KNOW IS NOTHING COMPARED TO SHARING YOUR TEST RESULTS.
This means your still in on the game since test results have got nothing to do with you asking idiot questions.

You see you're don't know what I was referring to. Atleast remember on what topic you talked to me on. Ok I'm not going to continue on this nonsense. I hate ping pong arguments who's the best.
Have a good day.
Bye bye.

@all

Also, we can say that with a 120v/12v Dual toroid transformer set-up, it came close, not close close, but close, so this bodes well when I get my 120v/120v set-up going. I just got a call from my supplier saying the transformers are in so tonight we can start again. This time...... no mistakes.

  Yesterday I purchased a 400 VAC cap @ 5 uF and 45 uF -- and I checked the C values with my meter.

  I placed the cap in parallel with the primary of trafo 2, according to the circuit suggested by Jack Noskils -- but I have not attempted "tuning".  I simply used the C values that I had on this cap.

  The results @ Vin = 122.5 V and Vout = 70.1 V (approx) -- at these voltages, I have checked as explained above and the Kill-A-Watt meters work just fine.

1.  Without cap
Pin = 23.4 W;  Pout = 17.8 W; eff = Pout/Pin = 76% with these trafos.

2. With 45uF cap
Pin = 37.8 W;  Pout = 17.8 W; eff = Pout/Pin = 47%  -- interesting that Pin went up with this, so that eff went down.

3.  With 5 uF cap
Pin = 23.4 W;  Pout = 18.0 W; eff = Pout/Pin = 77% a modest improvement.

See photo.  Any ideas?  I have toroidal 1:1 transformers on order...

Jouleseeker:

Did you try reversing one side  of the transformer connections in case your transformer coils were wired the wrong way?
I find it makes a difference, although my specs aren't near Jack's -  so nothing to shout about. - Except reversing connections and repeating the experiment does make a huge difference.
Good Luck.
