Can Buck Boost Ttransfomers be used on three phase corner grounded delta systems?

Issue:
Buck Boosting Corner Grounded Delta system

Product Line:
LV Transformers

Environment:
Applies to Buck Boost Transformers by SquareD/Schneider Electric

Cause:
Corner Grounded Delta systems may have to have voltage increased or decreased


Resolution:
The grounded leg must be used as the common leg when using an open-delta 3 phase Buck or Boost Autotransformer connection or with 1ph single phase connection. The two ungrounded phase conductors may be used for a 1phase Autotransformer connection.
