Re: [TCML] HV Transformer Winding

That is a very nice transformer you have there. Did the cores come from a Radar transformer? What did you use in between turn layers? 

I also must commend you on your web site. very spiffy. =)

Subject: [TCML] HV Transformer Winding 

I have posted this on the 4hv.org forum, but as I started the project on 
here I will include it on here as well. 



Hello. 

I am currently rewinding a HV transformer (details can be seen here 
http://homepage.ntlworld.com/follies/tesla/radartransformer.html ) and I am 
uncertain which way (clockwise or counter clockwise) the two secondary coils 
should be wound. 

I have one on each outer leg with the primary in the middle. I know there 
are issues with my design, in so much as the centre primary leg has eight sq 
inches of core while both the outer secondary's only have four square inches 
each. But I can still get 1 volt per turn on the secondary's with this setup 
(as explained in my link) 



I won't be connecting the inner ends of the secondary's to the core as it 
will all be in an insulated plastic tub under oil, but with the inner turns 
of each coil at zero volts it is easier on the insulation. I will be 
connecting the secondary's in series but I want their inner most ends to be 
a zero volts , so do I need to wind one secondary anti-clock and the other 
clockwise, or wind both in the same direction. I'm 99% certain I need to 
wind one clockwise and the other anti-clock, I just want to check before 
it's too late ! 



Regards 



Phil
