Gave us:



BTW It is possible to make 50/60Hz mains transformers with very little
core material - just a post inside the concentric windings. Of course the
magnetising inductance is low, so Imag is high, and they puke flux
everywhere, but the core losses are extremely low (what with there being
mostly no core), and the overall result can be cost-effective.


Bwuahahahahahahaha!

its called a partial-core transformer.

http://www.ewh.ieee.org/r10/nzs/IEEENZS_Postgrad_Presentations_2006.pdf

contains a brief description of such a device.

Prof. Bodger at Canterbury University, NZ, has done a lot of work on
these.

Terry, responding to MassiveWrong is like trying to piss into the wind, it
all comes back in your face.
Cheers,
Harry

wrt the diatribes, sure.

I thought others might be interested in partial core transformers though.

and its funny to see just how little he really knows about transformers :)

Cheers
Terry

It's not funny how little he knows... such a big mouth for such a
little brain.
