Protection of Industrial Power Systems Second Edition by T. Davies.

The protection which is installed on an industrial power system is likely to be subjected to more difficult conditions than the protection on any other kind of power system. Starting with the many simple devices which are employed and covering the whole area of industrial power system protection, this book aims to help achieve a thorough understanding of the protection necessary.

More Details:
In the years since the book was written there has been a great change in protection. Not in the principles, but in the relays which are now applied.

The development of electronic and microprocessor-based relays has been such that these are now a less expensive option than the electromechanical relay.

The problems which existed in the early days have been completely eliminated and the lower burdenand greater accuracy of these types of relay means that they are now the usual type of relay to be selected.

This does not mean that electromechanical relays have disappeared. Far from it. They still feature in the vast majority of installed equipment and so are still discussed at length in this new edition.

It would not do for me to ignore the help I have been given in preparing this new edition.

Vital aspects such as the modern cartridge fuse, types of relays, and the role of the current transformer are covered and the widely used inverse definite-minimum time overcurrent relay, the theory of the Merz-Price protection system and the development of the high-impedance relay system are critically examined. This new edition has come about in response to the dramatic change from the use of electro-magnetic relays to electronic and micro-processor relays which figure in practically all new installations. Therefore, although the theory and usage are the same, the application can be much improved owing to the increased range and accuracy and the added facilities provided with the modern relays. This book reflects the change and explains the technical advantages.
