This book provides an understanding of the nature of short-circuit
currents, current interruption theories, circuit breaker types,
calculations according to ANSI/IEEE and IEC standards, theoretical and
practical basis of short-circuit current sources, and the rating
structure of switching devices. The book aims to explain the nature of
short-circuit currents, the symmetrical components for unsymmetrical
faults, and matrix methods of solutions, which are invariably used on
digital computers. It includes innovations, worked examples, case
studies, and solved problems.
