Low insulating gas action - Electric power transmission distribution

If you know your breaker is unhealthy (low-low insulating gas 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 sf6 gas pressure switches plus one contact.Get price
