A three-phase transformer circuit is disclosed that includes a supply side, wherein the supply side is selectably configurable between a delta connection and a wye connection at a time of use and, a load side, wherein the load side is selectably configurable between a delta connection and a wye connection at the time of use. The three-phase transformer also provides for selecting an input voltage, from multiple input voltages, at the time of use, and for selecting an output voltage for the supply side, from multiple output voltages, at the time of use.
