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

[dieter]

Hope,


sorry, I came here trough an other forum subsection, the thread must be alias-linked somehow. So, yes, probably not enough proof for applying. A Killawatt Meter isn't saying much, as we know.

Just a recap, did these experiments:


1. watt meter and one normal 1:1 trafo, no load meter showed maybe about 5 watts. With load it showed about 25-30 watts, don't recall exactly.
2. Added second 1:1, just two trafos in series. Now little less light, meter readings were about the same.
3. Connected second trafo as explained. Now watt meter did not show any difference whether there was load or not. Amount of light was about the same as in test 2.
4. Removed first trafo and used trafo connected as explained here. Same results as in case 3, but now a bit more light because less losses.


So, tests 1 and 2 confirms that my watt meter was adequate.


Now we know that voltage is dropped by 50% and current is doubled when trafo is connected as shown. Looking at test 3, nothing changes from watt meter point of view, it still sees just one trafo connected to it. Why it does not see power taken from the second trafo ?


This is very simple thing to do and measure it. I don't have any tools to measure anything so this is the end of the road for me, for now. Anyone with scope can play with this if suitable 1:1 trafo is available for testing.

Sorry to ask but when you say:
4. Removed first trafo and used trafo connected as explained here. Same results as in case 3, but now a bit more light because less losses.
What you meen? What is the schematic of your best result? Does it use only one isolation transformer insted of 2?
Thank you!

In test 4 I used only 1 trafo connected as autotransformer. If you look at the pics in page 1 of this thread you will see schematic. It is simply two equal coils connected in series and load taken from the middle. Winding direction does not matter, but they have to be in same direction so use either CW/CW or CCW/CCW.


Purpose of test 3 was simply to isolate from the mains to be more safe to test.

Hi jack.
Thank you for reply!
So if i replicate this schematic

I have a one to one rasor only socket transformer so i want to replicate....
Can you give me some more advise?
