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.

...Jim Thompson

Indeed.

On a related note, I asked someone a little while ago why the "oral minority" who crap on about morality always seem to get caught sticking there peckers in the wrong places (eg pastor Ted et al). The response? people see themselves in others. The virtuous assume others are virtuous, so see no need to proselytise. The corrupt see corruption, thus spout off about it (at least until they get caught, then they tend to shut up, fast).

Methinks a similar argument explains MassivelyWrongs frequent "your all retards" outbursts.
