Ac power systems handbook 3rd edition

The book follows a logical progression from generating ac energy to the protection of life and property. General topics include:. How Much Protection? The degree of protection afforded a facility is generally a compromise between the line abnormalities that will account for most of the expected problems and the amount of money available to spend on that protection.

Each installation is unique and requires an assessment of the importance of keeping the system up and running at all times, as well as the threat of disturbances posed by the ac feed to the plant.

The author firmly believes that the degree of protection provided a power-distribution system should match the threat of system failure. In this publication, all alternatives are examined with an eye toward deciding how much protection really is needed, and how much money can be justified for ac protection hardware.

The attention given to the design and installation of a facility ground system is a key element in the day-to-day reliability of any plant. A well-planned ground network is invisible to the engineering staff. A marginal ground system, however, will cause problems on a regular basis. Although most engineers view grounding primarily as a method to protect equipment from damage or malfunction, the most important element is operator safety.

The V or V ac line current that powers most equipment can be dangerous — even deadly — if improperly handled. How much is entirely up to you. Setting up a safe and effective AC power system from the very beginning can help avoid costly downtime and repairs, provide backup power during system outages, and minimize workplace accidents.

This third edition is thoroughly revised and completely reorganized to reflect the changing demands of modern power systems. To ease navigation, many sections are now presented as separate chapters filled with updated and expanded information. Most notably, the author adds heavily in the areas of transient suppression hardware, electrical system components, and power system fundamentals.

Following a logical progression, coverage flows from power system operation to protecting equipment loads, selecting the right level of protection, grounding, standby power, and safety.

Along the way, the author paints a clear picture of the sources of disturbances, the tradeoffs involved for different options, and the advantages and limitations of various approaches. Streamlined to be a hands-on, user-oriented guide, the AC Power Systems Handbook offers expert guidance on designing and installing a safe and efficient power system.
