In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and 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

Despite the minimal maintenance requirements, inspecting a vacuum interrupter for wear or degradation without breaking the seal is challenging. If a vacuum interrupter fails, it often requires complete replacement, which can be more costly and time-consuming than servicing other types of circuit breakers.
Vacuum circuit breakers are generally operated with an operating mechanism with smaller operating energy as compared with those of other types of circuit breakers, because the vacuum interrupter employs disc-shaped "butt" contacts instead of finger-shaped contacts often used for SF 6 gas interrupter.. All other types of circuit breakers rely on some kind of …
