Power Transformers: Principles and Applications

Front Cover
CRC Press, Apr 12, 2002 - Technology & Engineering - 304 pages
Complete with equations, illustrations, and tables, this book covers the basic theory of electric power transformers, its application to transformer designs, and their application in utility and industrial power systems. The author presents the principles of the two-winding transformer and its connection to polyphase systems, the origins of transformer losses, autotransformers, and three-winding transformers and compares different types of transformer coil and coil construction. He describes the effects of short circuits on transformers, the design and maintenance of ancillary equipment, and preventative and predictive maintenance practices for extending transformer life.

Page 1 - Standards, a transformer is an electric device, without continuously moving parts, which by electromagnetic induction transforms electric energy from one or more circuits to one or more other circuits at the same frequency, usually with changed values of voltage and current.
Page 1 - ... wide band of frequencies, they are used to provide direct-current isolation, signal splitting and combining functions, specific current or voltage ratios, impedance matching, and phase inversion. The Institute of Electrical and Electronics Engineers, Inc. (IEEE) has defined a transformer as follows: "A static device consisting of a winding, or two or more coupled windings, with or without a magnetic core, for introducing mutual coupling between circuits. Note: Transformers are extensively used...
