Hi. I understand the basics of this question but don't feel 100% confident on the phase shift on the 4 types of transformer connections. My books don't seem to bother illustrating the phase shift either. I know a delta- wye has a 30 degree phase shift through it (but I don't know which side leads). I think a wye-wye or a delta-delta would each have zero phase shift.
If this NCEES problem had one delta-wye transformer and another wye-delta transformer in parallel, would it cause any problems on the load side? It seems the 30 degree shifts would negate each other on the shared secondary side. Thanks for the help!
