Protective Relaying: Principles and Applications, Second Edition
Maintaining the features that made the previous edition a bestseller, this book covers large and small utility systems as well as industrial and commercial systems. The author provides a completely new treatment of generator protection in compliance with governmental rules and regulations and supplies expanded information on symmetrical components. The text delineates individual protection practices for all equipment components; furnishes an overview of power system grounding, including system ferroresonance and safety grounding basics; analyzes power system performance during abnormal conditions; describes the relationship of input source performance to protection; and much more.
