Low sf6 gas action - Electric power transmission distribution

If you know your breaker is unhealthy (low-low Sulfr hexafluoride for example) the fastest way to trip it (faster than BF or any other protection) is to let it trip itself. You are only a single contact operation away from picking up the trip coil then, so you trip speed is the speed of your motorized insulating gas pressure switches plus one contact.
