    Conversely, no-load-break bypass switches do not offer the flexibility of the load-break bypass switch design. With no-load-break bypass designs, the automatic transfer switch must be in the same position (i.e., normal or emergency) as the source to which the load is being bypassed (i.e., normal to load or emergency to load).

  • SF6 Circuit Breaker: What Are They? (Types and Operation

    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.
