three phase transformer
(OP)
hi guys I'm trying to get my head clear on transformer winding polarity on a three phase transformer. what are the effects of one winding having an incorrect polarity wrt the other 2. I know the phase relationship will change but physically what will happen?
many thanks for your in-depth replies as per.

Draw a delta…
Now take one vector and flip it 180 degrees. Figure your voltage from there.

We had to get a new nameplate made several years ago, for a Y-Y 60 degree shift transformer. They changed the winding, and never remade the nameplate.

My point is read the nameplate, but question it's accuracy from time to time. After all engravers only put what they are told.
