Power transformers

by John J. Winders

This timely reference illustrates how to specify, operate, and maintain power transformers properly in a utility or plant environment-emphasizing the importance of magnetic properties and how the choice of a core design can affect a transformer’s electrical properties, especially during faults and unbalanced operations.Addresses the economic trade-offs of power transformer selection in real-world applications.Power Transformers features extensive coverage onzigzag, Scott, tee, wye, and delta connectionstap changing under load and variable phase shiftingadvantages and disadvantages in coil selection and constructionsymmetrical componentstransformer nameplate rating, thermal capability, and rate calculation of loss of lifeabnormal operating conditions such as overloads, short circuits, single phasing from primary fuse operations, ferroresonance, and voltage surgesComplete with equations, illustrations, and tables, Power Transformers is an essential reference for power, electrical, and ma
