[TCML] Homebuilt Transformer - Can you add shunts?



Hello.

I am in the process of rewinding a transformer from a UK RADAR set. A
drawing of the core with sizes can be seen here

Eventually it will be a 2 to 3 Kva unit   ( originally it was 2Kva 8.25 kv @
250 m/a with  AWG 14 on the primary & AWG 24 on the secondary)

Before I start finalizing turns etc, I wondered can I introduce a magnetic
shunt to limit the shorted current, like NST's use, and thus avoid having to
use a Ballast?

If so would I just need to introduce some packing between the jointing faces
?

 

Richie Burnett has done a similar thing with some inductors to stop
saturation at

Looked at a few other webpages on homebuilt transformers but none seem to
use this method for a transformer though, but I thought this was the same
method employed by NST's

 

Thanks

Phil
