Scope: Vacuum switches now dominate the medium-voltage sector (below 30 kV) for all power switching functions. Allan Greenwood is a world authority in this field; in this book he shows how vacuum arcs and current interruption in vacuum are different from gaseous arcs and interruption in gas circuit breakers, and leads the reader to understand these differences - thereby enabling successful design, construction and use of vacuum switchgear. This comprehensive treatment (including an introductory historical perspective) makes the book useful for users and manufacturers as well as designers.
The book will effectively act as a companion to SF6 Switchgear which covers high voltage switching.
