The operating principles of three-phase transformers and their construction will be explained. Various types of connections including phase shift, transformation ratio, and voltage ratio will be explained. Delta-wye connection and their applications will also be discussed with examples. Parallel operation of transformers to share the load will be explained. Circuit analysis techniques will be discussed by defining general nodes, principal nodes, branch and loop/mesh, and these terms will be applied to perform the mesh and nodal analysis. Finally, power factor correction studies for industrial power systems will be discussed with practical examples.
