Switchgear Protection & Power Systems

The book, Switchgear Protection And Power Systems, deals with principles of current interruption; constructional and operational aspects of various circuit breakers; fault current calculations; role of network analysers and digital computer in the calculation of fault current of complicated system networks; constructional and operational aspects of electromagnetic protective relays and protective systems for generators, transformers, motors and transmission lines. It also provides a detailed study on static relays and static protection schemes, power system controls, application of digital computer; microprocessor for load-frequency control, and back-up protection as well as power system stability. The book is profusely illustrated by clear sketches, diagrams and graphs. The book is supplemented with solved and unsolved problems, summary and provocative questions.
