VACUUM ARC RECOVERY OF VACUUM CIRCUIT BREAKER
High vacuum possesses extremely high dielectric strength. At zero current the arc is extinguished very quickly, and the dielectric strength is established very quickly. This return of dielectric strength is because of the vaporized metal which is localized between the contacts diffuses rapidly due to the absence of gas molecules. After arc interruption, the recovery strength during the first few microseconds is 1 kV/µs second for an arc current of 100A.
Because of the above-mentioned attribute of vacuum circuit breaker, it is capable of handling the severe recovery transients associated with short-line faults without any difficulty.
