Digital protection is based on the use of computers in power line relaying. Since the late 1960s, digital devices and techniques have been applied to almost all new protection schemes. Today the technology is moving towards standardised hardware platforms; at the software level, however, there remains a huge variety in approaches and protection algorithms. This book gives a fairly detailed understanding of the principles and techniques underlying the application of digital technology and algorithms to protection. It avoids going into detail of specific products: up-to-date information on these is available from the manufacturers. Instead it aims to give the reader a thorough understanding of the generic problems of digital protection. The text covers the mathematical basis of numerical techniques and relay algorithms, the basic elements of digital protection and the fundamentals underlying the commonest algorithmic forms, particularly as applied to line protection. It deals with the fundamentals of travelling-wave techniques and their application to transmission lines, and with digital differential protection of transformers and lines.…

About the Author
Allan T. Johns is Professor of Electrical Engineering and Head of the School of Electronic and Electrical Engineering at the University of Bath. He is the author of over 200 journal papers, and in 1982 he was awarded the degree of Doctor of Science for his original and substantial contribution to knowledge in the area of digital protection and simulation of electrical power systems.
He worked for nine years in British industry, both in electricity supply and in manufacturing, and is still heavily involved in industrial consultancy. He is a Fellow of the IEE, a Series Editor for the IEE Power Series of books and Tutorial Editor of Power Engineering Journal. Among the awards he has earned are the IEE Crompton Premium in 1983 and the IEE Power Divisional Board Premium in 1989.
Salman K. Salman is with the School of Electronic & Electrical Engineering at the Robert Gordon University in Aberdeen. His research interest covers analysis and protection of power systems. A graduate of Baghdad University, Sheffield University and UMIST, he is the author or co-author of more than 35 papers. He spent six years working in the electricity supply industry, and before his current position was Associate Professor at the Behghazi University, Libya. Dr. Salman is a Member of the IEE and a Senior member of the IEEE.
