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

@all

Come on guys. All we are doing is reporting our results and getting help from some so no need to attack each other for tidbits.

So from suggestions of @JouleSeeker to use a Kill-a-Watt counter, I got one today.

And also @MH's post;

Wattsup:
For your DC current measurement you are at nearly the rock-bottom output from the digital clamp meter.  Hence your accuracy is very poor.  I would suggest that you just use a regular digital multimeter or an analog ammeter with the proper maximum scale to get a better DC power calculation.

So I put the DC output through a multimeter as amps and to my greatest dismay, I saw only 45.5mA. I also took off the Variac and went direct to mains via the Watt Counter.

So while the system is running, with the regular clamp meter on the dc load, I am getting 0.2 amps but through the multimeter, I am getting 45.5mA. There is a great discrepancy between these two so @MH was more then right about that and good thing he caught it so quickly. Thanks man. I was wondering why the bulb was so dim with that voltage at .2 amps it should have been brighter then that, but when I saw .2 amps and did the math, hey, of course it looked good. We try to do our best efforts by the book, but sometimes things can get past us.

So here is a recap of the new numbers;
INPUT VIA WATT COUNTER: 121VAC @ 0.27 AMPS OR 32 WATTS
INPUT by meters A: 121.9 VAC @ 0.24A = 29.259 WATTS
OUTPUT B: 57.3 VAC @ O.47A = 26.93 WATTS
OUTPUT C: 43.1VDC @ 0.0443A = 1.90933 WATTS
TOTAL OUTPUT: 28.83933 WATTS

I put a small video here but it is still uploading (2hrs left);

So back to the drawing board. I think my new transformers should be in by Monday so I will play around with this some more and see what gives. I think guys with clamp on ammeters that only provide one decimal point precision at low amp readings is not enough and can easily lead one to see OU where it is not, YET that is.

Soon.

  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.

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

Hi Microcontroller thanks for your PM comment that you send. The thing is that you disabled the reply cause I was going to send you my thanks. Another thing if I know something on anything I share it with others not try to bring them down with my comments. It's good that we behave like grown ups to each other not like id**ts.
