Comprehensive in scope, this book, now in its fully updated second edition, was written to fill the need for a truly applicationsoriented text on electrical distribution systems. All critical aspects of power production, distribution, control, conversion and measurement are clearly presented. The authors place emphasis on realworld applications, examining electrical distribution and associated system operation from a user's or technician's point of view. The use of an ‘electrical power systems' model facilitates the reader's comprehensive understanding of electrical distribution, utilizing power distribution as a key starting point, and then clearly delineating the relationship to other important associated systems. The final chapter of this new edition has been refocused to emphasize the economics of distribution systems, computer power requirements and current environmental considerations. The book will serve as a valuable desk reference for the working engineer, contractor or technician who needs a thorough applicationbased guide to finding the best solutions to today's electrical distribution challenges.
