It is appropriate that I first acknowledge my appreciation to Professor Leo Grigsby for inviting me to
prepare the chapter on power transformers for the first edition (2001) of his now very popular Electric
Power Engineering Handbook. From this evolved the recognition that two chapters from the 2001
Handbook, those for (1) substations and (2) transformers, could be extracted, expanded, and be offered
as stand-alone books while retaining the composite association with Professor Grigsby’s overall work.
Thus, the first edition of Electric Power Transformer Engineering was offered by CRC Press in 2004.
As editor of the book, my charge to the chapter authors was to direct their messages to engineers who
know the basic physics, or applications, or possess a hands-on working knowledge of power transformers.
Thus, it is believed that all persons with a power transformer background experience, be they
merely curious, seasoned professionals, or acknowledged experts, will find much in the book with which
to relate, and that all such readers will glean material appropriate to their individual degree of expertise.
