Vacuum Bottle Insulation Integrity Test

WHAT IS VACUUM BOTTLE INTERRUPTER? A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in vacuum medium. The operation of switching on and closing of current carrying contacts and interrelated arc interruption takes place in a vacuum chamber in the breaker which is called vacuum interrupter. In electrical engineering, a vacuum interrupter or Vacuum Bottle is the core component of medium-voltage circuit-breakers, generator circuit-breakers & high-voltage circuit-breakers. Separation of the electrical contacts results in a metal vapour arc, which is quickly extinguished. Vacuum interrupters are widely used in utility power transmission systems, power generation unit, power distribution systems for railway, arc furnace application and Industrial plants. Fig.1.
