This book provides a broad perspective of vacuum switchgear drawn from
the author's many years of experience in this field. Allan Greenwood
describes the development of the technology from the earliest beginnings
to the most recent designs now on offer by leading companies around the
world.
The book starts with a solid foundation in the physics of the vacuum
arc, in vacuum breakdown and in the fundamentals of current
interruptions in vacuum. For the user there is an exhaustive chapter on
applications, which spans all devices from contactors through switches
and reclosers to power circuit breakers. Maintenance is also addressed.
There are four chapters on different aspects of design and another on
testing, which should appeal to the designer. The chapter on
manufacturing concentrates on the interrupter as its manufacture is so
entirely different from that required for oil and gas-blast circuit
breakers. The treatment is comprehensive so the book will be useful to
users, designers and manufacturers alike, and to students who wish to
become acquainted with the subject.
