Abstract
Disclosed are example embodiments of a dead tank circuit breaker for protecting electrical components against electrical surges and other voltage anomalies such as transient overvoltages. The circuit breaker includes: one or more vacuum interrupters; a current bypass circuit electrically coupled to the one or more vacuum interrupters; a dead tank encasing and hermetically sealing the one or more vacuum interrupters and the current bypass circuit, wherein the dead tank is pressurized with a non-SF6 gas; and a controllable mechanism coupled to the one or more vacuum interrupters and to the current bypass circuit. The controllable mechanism is configured to actuate the one or more vacuum interrupters and the current bypass circuit to open or close a main circuit path such that any pre-strike arcing occurs on the current bypass circuit instead of the one or more vacuum interrupters.
