Zusammenfassung:Experimental investigations of generator circuit-breaker prototype with parallel vacuum interrupters were carried out. The prototype braking and making capacity were high enough to use such circuit-breaker in generator circuit. The current dividing between vacuum interrupters allowed to achieve breaking current 80 kA and making current 150 kA peak. The authors found the limit of irregularity of current distribution during switching operation.
