Description:

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 on

[*]zigzag, Scott, tee, wye, and delta connections
[*]tap changing under load and variable phase shifting
[*]advantages and disadvantages in coil selection and construction
[*]symmetrical components
[*]transformer nameplate rating, thermal capability, and rate calculation of loss of life
[*]abnormal operating conditions such as overloads, short circuits, single phasing from primary fuse operations, ferroresonance, and voltage surges

Complete with equations, illustrations, and tables, Power Transformers is an essential reference for power, electrical, and maintenance engineers; power technicians, planners, and designers; and for upper-level undergraduate and graduate students in these disciplines.
