Comprehensive in scope, this book, now in its fully updated second edition, takes an applications-oriented approach to electrical distribution systems. All critical aspects of power production, distribution, control, conversion and measurement are presented.
The authors place emphasis on real-world 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 applying that relationship to other important associated systems.
The final chapter of this new edition is re-focused to emphasize the economics of distribution systems, computer power requirements and current environmental considerations. The book provides a valuable desk reference for the working engineer, contractor or technician who needs a thorough application-based guide for finding the best solutions to today's electrical distribution challenges.
