THREE-PHASE TRANSFORMERS
Most of the transformers used in power generation and distribution systems are three-phase. These transformers can be constructed from three single-phase transformers connected in a three-phase bank (Fig. 3.20). They can also be constructed by wrapping three sets of
Three-Phase Transformer Connections
The primary and secondary phases of any three-phase transformer are independently con- nected as a wye (Y) or delta (.::). The possible connections of a three-phase transformer are.
