Switchgear and Power System Protection

This comprehensive introduction to system protection covers the underlying principles of operation of switchgear and several relay protective schemes used in power systems and elucidates their important requirements to provide the basis for design criteria. Besides, the book contains a detailed treatment of protective schemes used to encounter fault conditions that may occur individually in generators, motors, transformers, busbars, and distribution circuits. Protection against switching surges and lightning is also discussed.

The final chapter on power system management provides a simple introduction to that important area in order to emphasize the importance of optimal economic operation of power systems in which protective schemes under fault conditions play a crucial role towards continuity of electrical supply with minimum damage to life, equipment and property.
