Since the vacuum arc is the key element in the vacuum interrupter, some knowledge of its structure and behaviour is essential to understanding the operation of vacuum switchgear. The name vacuum arc is really incorrect, indeed, it is a contradiction. As Ecker points out 'If there is a vacuum there is no arc, and if there is an arc there is no vacuum'. A more exact name would be metal vapour arc, since the arc which forms when current-carrying contacts separate in a vacuum 'burns' in the metal vapour of the contacts. The name vacuum arc is now so pervasive and so uniformly accepted that I use it throughout this book as meaning a metal vapour arc.
