S1r PDF coil description and discussion !!!!

[Park34]

Transformers consist of a core, the primary, and secondary coils.

The core is laminated and made of soft iron.

The transformer equation is:

Vprim = Nprim

Vsec    N sec

I am confused as to why it would be a short, only the HV would be connected to the nail, the other ones have the coating on them, atleast thats how i read it and saw in the video

Look at the drawing again. Coils 2 and 3 are tied together. One side of coils 2 and 3 is hooked to 12v pos, the other side of coils 2 and 3 is hooked to 12 v neg, that would be a dead short without the light bulb.

Also if the main windings are touching the nail it's just going to flow thru the nail instead of thru the turns in the winding. Also, if the windings are touching seems to me it won't flow around the windings, instead it will flow straight thru, easiest path.

That will get you started.  Search user *Otto    50 turn test, and you can read to your heart's content.

Well I read the "beginning" of this thread http://www.overunity.com/index.php?topic=2235.msg29058.
And if I look at this circuit, I have to say, in my opinion this is nothing else than a current transformer in a little bit strange configuration, as you connect both primary and secondary at one side. Sure a current transformer will give HV spikes if the resistance is high. Actually if you would not connect any load resistance, the voltage would spike very very high. This is also why in practise current transformers are always delivered with a short circuit clamp for safety.
Well as I said didn't read the whole, but can somone in short explain what is the difference between a current transformer and this setup? I don't wanna go too much offtopic, but as s1r used the same layout it's not too offtopic anyway.
What I can understand is, that most of the power measurements people are doing here don't really yield usable results, as it is extremely difficult to measure impulse circuits even with very expensive professional equipment. The best power meters are still the old ones (which work with a heating wire), as they don't fall short of the reactive current problem.
