  • The basics of high voltage switching equipment in power

    Feb 20, 2021 · Most dead tank SF6 gas circuit breakers have a density switch and a two-stage alarm system. Stage one (commonly known as the alarm stage) sends a signal to a remote monitoring location that the gas circuit breaker is experiencing a gas leak, while stage two sends a signal that the gas leak has caused the breaker to reach a gas level that can no longer assure proper operation of the breaker in the event of a fault current condition that must be cleared. Once the breaker reaches stage two
