The history of vacuum switchgear starts in mid 1920's but commercial vacuum switching equipment did not appear until the late 1950. Since then the power industry, electric utility companies and commercial customers alike, applied vacuum switchgear in an increasing array of system configurations and schemes. Although about 40 years passed from the historical moment of the first vacuum circuit breaker the vacuum technology is still considered to be "new" and often misunderstood or misapplied. Numerous technical papers and a few valuable books have been published on the subject of vacuum arcs and vacuum switchgear but we still have a way to go.
