Abstract: Gas insulated switchgear for isolating a power system can include three individually poled breakers. A timer circuit actuated after a preset time delay in response to a discrepancy in position of the three individually poled breakers can include three contacts, each contact associated with one of the three individually poled breakers. A supervisory relay can include a status lamp, a first normally open contact connected to the status lamp, a circuit breaker closing coil, and a second normally open contact connected to the circuit breaker closing coil, the supervisory relay connected to the timer circuit such that power to the timer circuit closes the first and the second normally open contacts.
