what can you tell us about "Scott-T"? I only found a patent which suggests

I've seen it used industrially to substitute as a cheap Y transformer. You can even produce an equivalent of a grounded center Y by having a tap off center on the winding that connects between a phase and the center tap of the other winding. The windings are not as equally balanced as a true Y, but from the outside, you still have three ends for 3 phases and a center node to connect ground.


The Scott-T is just one permutation of the many possible, to change phase angles using two or more transformers.
