  • Low SF6 action - Electric power transmission

    All practical gas leaks are slow leaks, which means that the moment when the densimeter announces stage 2 is the last moment to safely open the breaker. When the densimeter reaches stage 2, two actions are possible: (1) Lock out all trips, because tripping after *passing* stage 2 is dangerous. (2) Trip immediately.

    Oct 23, 2020Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.

    Although pure SF6 is not toxic, it contains no oxygen and will therefore not support life. The high density of SF6, five times that of air means that any leak will tend to cause the gas to accumulate in low areas such as cable trenches, and operators should be made aware of the danger of suffocation.
