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.
