Abstract: A system and method for interrupting power in a three-phase power system interrupts power in the faulted phase and the next sequential phase at high speeds, while interrupting power in the remaining phase at a normal operation speed. Limiting high-speed interruption to only two phases requires significantly less energy storage than implementing high-speed interruption in all three phases. When hybrid circuit interrupters are used, the need to wait for a zero-crossing in the current signal in order to initiate interruption operations is eliminated.

Abstract: A vacuum interrupter including a first movable contact and electrode contained within a vacuum chamber, a second movable contact and electrode contained within the vacuum chamber, a first actuator operably coupled to the first movable contact, and a second actuator operably coupled to the second movable contact. The vacuum interrupter also includes a first bellows and first bellows plate operably coupled to the first movable electrode, as well as a second bellows and second bellows plate operably coupled to the second movable electrode. Additionally, the vacuum interrupter includes a first pressure chamber located between the first actuator and the vacuum chamber, and a second pressure chamber located between the second actuator and the vacuum chamber.
