CONNECTIONS FOR THREE-PHASE TRANSFORMERS
CONNECTIONS FOR THREE-PHASE TRANSFORMERS109. Methods of connecting the windings of three-phase transformers (Standard Handbook for Electrical Engineers). The windings of each component transformer are connected to the external circuits just as though this component were a one-phase unit; i.e., the primaries can be connected either Y or delta. Moreover, the relative advantages of the Y connection and the delta connection are quite the same with one three-phase transformer as with three one-phase transformers. The delta connection is advantageous in some cases, in that if the windings of one phase become damaged by short circuiting, grounding, or any other defect, it is possible to operate with the other phase windi…
