Editorial Reviews

Based on seminars he has given to help prepare electric utilities for deregulation, former electrical engineer Kennedy explains to technical and non-technical readers the concept of quality power and how it can be used to improve a company's competitiveness now that the industry is turning dog-eat-dog. He looks at power quality from the perspectives of its characteristics, standards, solutions, wiring and grounding, measurement tools, surveys, economics, and future trends. He includes a glossary of technical meanings. Annotation c. Book News, Inc., Portland, OR (booknews.com)
