Electrical Transients in Power Systems

The transients that accompany sudden changes in power systems conditions, brought about by switching operations, faults and the intrusion of lightning, are dealt with in this edition. Such transients are inevitable when operating a power system and, if misunderstood, can create serious problems by overstressing components. The early focus of the book is on the fundamental factors that control the form of transients. The text is then devoted to the calculation and computation of transient currents and voltages. The necessary physical parameters for these computations are supplied and the models for system components are developed. A distinction is drawn between lumpy and distributed circuits, and state-of-the-art computation tools are introduced.

Author Biography

Dr. Allan Greenwood is presently Philip Sporn Professor of Engineering at Rensselaer, the oldest engineering school in North America. His professional career, which started with a B.T.-H. apprenticeship in 1940, has been spent about equally in industry and university environments. His particular interests are in power switching equipment and the interactions of such equipment with power systems. He was one of the small team that developed the first high power vacuum interrupters for the General Electric Co. (USA) in the 1950s and has been involved with this technology ever since. He holds many patents and has published widely on this subject. He is the author of Electrical Transients in Power Systems (John Wiley & Sons, 2nd edn, 1991). Dr. Greenwood is a life Fellow of the IEEE, an Attwood Associate of CIGRE and a former Visiting Fellow of Churchill College, Cambridge.
