If the danger limit is reached the safety devices immobilize the breaker. The overriding safety devices see to it that a fault in the control circuit does not permit the compressor to build up excessive pressure in the high-pressure reservoir or continue to pump gas into the atmosphere in th...
They arewidely used nowadays for generator ratings rangingfrom 100 MVA to 1300 MVA.SF6 circuit breakers are generally applied wheninterrupting capabilities of 63 kA to 120 kA arespecified, while air-blast generator circuit breakers aredominant when a higher interrupting capability isrequired, ...
