<strong>Transformer</strong> engineering is one of the earliest sciences within the field of electric power engineering, and<br />

power is the earliest discipline within the field of electrical engineering. To some, this means that<br />

transformer technology is a fully mature and staid industry, with little opportunity for innovation or<br />

ingenuity by those practicing in the field.<br />

Of course, we in the industry find that premise to be erroneous. One need only scan the technical<br />

literature to recognize that leading-edge suppliers, users, and academics involved with power transformers<br />

are continually reporting novelties and advancements that would have been totally insensible to engineers<br />

of even the recent past. I contend that there are three basic levels of understanding, any of which may<br />

be appropriate for persons engaged with transformers in the electric power industry. Depending on dayto-day<br />

involvement, the individual’s posture in the field can be described as:<br />

• Curious — those with only peripheral involvement with transformers, or a nonprofessional lacking<br />

relevant academic background or any particular need to delve into the intricacies of the science<br />

• Professional — an engineer or senior-level technical person who has made a career around electric<br />

power transformers, probably including other heavy electric-power apparatus and the associated<br />

power-system transmission and distribution operations<br />

• Expert — those highly trained in the field (either practically or analytically) to the extent that<br />

they are recognized in the industry as experts. These are the people who are studying and publishing<br />

the innovations that continue to prove that the field is nowhere near reaching a technological<br />

culmination.<br />

So, to whom is this book directed? It will truly be of use to any of those described in the previous<br />

three categories.<br />

The curious person will find the material needed to advance toward the level of professional. This<br />

reader can use the book to obtain a deeper understanding of many topics.<br />

The professional, deeply involved with the overall subject matter of this book, may smugly grin with<br />

the self-satisfying attitude of, “I know all that!” This person, like myself, must recognize that there are<br />

many transformer topics. There is always room to learn. We believe that this book can also be a valuable<br />

resource to professionals.<br />

The expert may be so immersed in one or a few very narrow specialties within the field that he also<br />

may benefit greatly from the knowledge imparted in the peripheral specialties.<br />

The book is divided into three fundamental groupings: The first stand-alone chapter is devoted to<br />

Theory and Principles. The second chapter, Equipment Types, contains nine sections that individually treat<br />

major transformer types. The third chapter, which contains 14 sections, addresses Ancillary Topics associated<br />

with power transformers. Anyone with an interest in transformers will find a great deal of useful<br />

information.<br />
