Abstract
A three phase transformer circuit is provided that includes a supply side, wherein the supply side is selectably configurable, via the use of se of terminal boards, 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, via the sets of terminal boards, at the time of use, and for selecting an output voltage for the supply side, from multiple output voltage, at the time of use.
