Short-Circuits in AC and DC Systems : ANSI, IEEE, and IEC Standards

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.

• An up-to-date reference and practical guide on power system analysis, exploring new trends and state-of-the-art technology.
• Includes studies based on the author’s 45 years in solving many challenging real-world problems of power systems and analyzing and studying industrial and utility power systems, which are included in examples and problems.
• Chapters include exercises with solutions.
• Case studies and examples provided throughout.
