    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

    For instance, a transformer may be rated 121kV on the primary, 15kV on the secondary and 4kV on the tertiary winding. These are voltage ratings and the power ratings are generally the same for all three windings and independent of the voltage ratings, there are instances where the tertiary may have a lower power rating.
