490 Protection and Switchgear is designed as a textbook for undergraduate students of electrical and electronics engineering. The book aims at introducing students to the various abnormal operating conditions in power systems, and the apparatus, system protection schemes, and the phenomena of current interruption, to study various switchgears. The book describes in detail the protection principles of each element of the power system network. The details of relay design and relay settings have also been covered. Further, the book contains a wide coverage of digital-numerical relaying schemes,. Besides the relays, the book covers detailed theories of the circuit breaking phenomenon,. and the construction and working of switchgears. The book is pedagogically rich with detailed relay and circuit diagrams, numerous solved examples, review questions, multiple choice questions, and numerical exercises in each chapter. At the end of the book, an additional chapter on recent developments in protective relays covers the application of artificial intelligence techniques in protective relays and discusses the concept of synchronized phasor measurements and wide area protection, along with other important topics.
