A Kapanadze generator replication - Febuary 2013

[Magluvin]

Hello to all,

Having re read Vladimir Utkin's page I have made a new secondary coil. I have wound it from the center, working out in the same direction as per the drawings. As you can see from the attached I have made the primary winding a pancake style. It has got far too late to do any further testing. So will try and let you all know what results I get in the next couple of days.

Cheers Grum.

Hey Grum

Ive gone through Utkins files a good bit. Is your secondary 2 separate coils wound oppositely and connected in the middle? Like to start winding the first half to the middle the wind the rest in the opposite direction.

From what i understand, it is the 'electrical' field of each half of the secondary coil that is suppose to enhance effects.

Hello to all,
Many thanks for your encouragement, it is most appreciated. I just wish I had some encouraging news in return!!
The pancake coil was a complete flop.This was removed in place of a more conventional cylindrical type with 10 turns. Still no output.
For zcsaba77. Yes I did make the primary movable along the length of the secondary. And many thanks for the link to The old scientist, very interesting, and I feel he is on to our joint goal!!
For Mags, Yes the windings are done in the same direction, starting from the center.
For Tika, Thanks for the info. I agree, being a Welshman, French is much easier to understand than Russian!!

For all.
I think the secret lies in :- http://www.free-energy-info.com/Utkin.htm   Secret 3. 1  THE ASYMMETRICAL TRANSFORMER BASED
ON THE SHORT-CIRCUITED COIL
The whole look screams Kapanadze.
I have a couple of questions. My coil has a resonance of approximately 470Khz, now according to the text the primary frequency should match. How do you get a spark to go that fast?
Am I right in assuming that more turns lowers the self resonant condition? Or what about a coil with more insulation (other than Enamelled ) Therefore increasing paracitic capacitance?
My conclusion is that we should perhaps look at a solid state driver. Like The old scientist is using. I feel we would have more chance of mutual resonance.
Good luck to us all, Grum.

@Grumage,

From what I have read, and tested so far, the position of the primary is _very_ _very_ important to get any kind of output.  What do you drive it with ?

Hi Grum,

The kind of wire itself does not matter in itself, aluminium, for example works good too, and is a lot cheaper.  The bigger the insulation, the less parasitic capacitance.  The parasitic capacitance is inversely proportional to the distance between coils.  That is why a lot of tesla coil primaries are flat with widely spaced spires.   The length of the wire in the coils is very important if you want to generate standing waves, Utkin talks about it in his book. 

For the sparks, what you can do is tune the primary to 470kHz using parallel capacitors.  The sparks generator can then be finely tuned to a sub harmonic frequency, like 47kHz, or 23.5kHz.  The primary should still be vibrating strongly after 10 or 20 cycles, if the tuning is right.

Good luck!
