| Titre : | Transients in power systems | | Type de document : | texte imprimé | | Auteurs : | Lou van der Sluis, Auteur | | Editeur : | Chichester, New york, Weinheim : John Wiley & Sons,Ltd | | Année de publication : | 2001 | | Importance : | 207 p. | | Présentation : | couv. ill. en coul., ill. | | Format : | 24,8 cm. | | ISBN/ISSN/EAN : | 978-0-471-48639-8 | | Langues : | Anglais (eng) | | Catégories : | ELECTROTECHNIQUE
| | Index. décimale : | 10-05 Electronique de puissance et industrielle | | Résumé : | Transient current and voltage peaks in a power network frequently result in damage to system components. Occurrences range from voltage oscillations after the interruption of short-circuit currents to the effects of lightning strikes. Encompassing the fundamentals of transient phenomena, this reference provides effective techniques for the prediction and limitation of transient behaviour.
With the current emphasis on quality of power supply, this concise treatment of transients in power systems will prove a valuable resource to practising power system designers, engineers, researchers and advanced students of electrical engineering.
Features Include:
An in-depth account of power transients and the transient analysis of electrical power systems, with descriptions of the latest industry standards.
Explanation of the basics of electrical circuit theory and the effects of transients in the full range of power networks and components.
Summary of the physical phenomena responsible for transient behaviour and the mathematical tools required to tackle it.
Detailed coverage of switching actions, switching gear testing and insulation co-ordination
Guidance in the testing of high-voltage circuit breakers and appropriate measurement techniques.
Focus on the current interruption process and the incorporation of arc modelling into transient programs such as EMTP, MNA, Xtrans and the MATLAB power system blockset. | | Note de contenu : | Contents:
