A thread in rec.radio.amateur.homebrew about the Peter Dahl
transformer
company possibly closing down lead me to this unusall transformer
design.

It's a 2KW AC mains transformer designed for radio towers to stop the
RF
getting into the mains supply.
What is the name for this kind of transformer?
Dahl calls it an "austin ring type" but that just refer to the Austin
insulator
company who also make tower lighting transformers. I'm searching for
the name for this paticular topology.
It looks like it should not work so I'd like to learn a bit more about
it. I'd like to know if it could be used for audio signal isolation.
