The issue of power quality is in the forefront as never before, as power suppliers, electrical engineers and technicians are all challenged to meet the needs of today's sensitive electronic technologies and other specialized uses of power. The scope of power quality problems which must be solved range from those found in the largest of power plants to the smallest electronic devices, and from the vastness of the nation's power distribution networks to the immediacy of devices sharing a wall outlet. This book was written to offer a practical resource for solving the full gamut of these problems. Avoiding highly technical explanations and theory, the case studies presented provide both end users and troubleshooters with detailed examples of what others have done to solve problems similar to those they are encountering. Each case history is structured to show how the problem was pinpointed, the specific symptoms presented, and how the solution was achieved. Sections include chapters which emphasize design, wiring and grounding, harmonics, and approaches to problem solving.
