Why buy, wire, and pay forever to heat three sets of windings when you only need one set?
I am not the designer and I cannot enforce this on designer. Been asking the same question to the designer why go with delta center tap transformer and he just goes on loops without answering question.
One reason could be voltage drop 480V three phase versus 480V single phase. The transformer primary feeder is at bottom basement of building and transformer sits on penthouse roof 200 feet up.
