Can anyone recommend a definitive and straightforward reference for the various ways we employ transformers and why?
The missing phase that acts like it's still there in a delta as long as you keep load under 57%.
corner grounding
center grounding a delta and the high leg - why did we do this?
blocking harmonics wye-delta
connecting delta loads to wyes.
virtual grounding.
1001 installation schemes - which are legal and good and which aren't and why?
and the illustration & explanation of the center tapped 240 to the home.
etc.
Engineering texts tend to overcomplicate matters to show off math you'll never use again in real life. Many of the references for installations stick to fuse and conductor sizing for the most common cases. The historical reasons behind some of the more esoteric configurations seem to be lost or getting lost. And making decisions when you have a square peg and a round hole combination are tough.
Is there a book like the excellent one on GFCI/AFCI but on transformers?
