    The key difference between g3 and insulating gas is that g3 is a gas mixture while insulating gas is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling

  • sf 6 Circuit Breaker Types, Working Principles Maintenance.

    Feb 20, 2021 · In a high-voltage circuit breaker like sf6 gas, current interruption is achieved by separating the contacts in a gas medium. The sf6 comprises both fixed and movable contacts enclosed in a gas system at a pressure of around 2.8 kg/cm 2. Whenever a fault arises, the movable contacts separate, and an arc strikes in between them.
