Power system protection
This book is primarily intended to be a textbook on protection, suitable for final year undergraduate students wishing to specialize in the field of electric power engineering and practicing relay engineers already working in this field.
It is assumed that the student is familiar with techniques of power system analysis, such as three-phase systems, symmetrical components, short-circuit calculations, load flow, and transients, in power systems.
The reader is also assumed to be familiar with calculus, matrix algebra, and Laplace and Fourier transforms, and Fourier series. Typically, this is the background of a student who is taking power option courses at a US university.
An important part of the book is the large number of examples and problems included in each chapter. Some of the problems are decidedly difficult.
However, no problems are unrealistic, and, difficult or not, our aim is always to educate the reader, help the student realize that many of the problems that will be faced in practice will require careful analysis, consideration, and some approximations.
