Protection of Industrial Power Systems

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. This book is intended to help achieve an understanding of the protection necessary and covers the whole area of industrial power system protection, starting with the many simple devices which are employed. Covers vital aspects such as the modern cartridge fuse, types of relays, and the role of the current transformer. Includes critical examination of 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. Describes commissioning and maintenance testing of equipment.
