  • How to pinpoint SF6 leaks quickly without the need to de

    May 21, 1999A halogen detector could detect the leak in the control box, but much more time would be needed to determine the source of the SF6 at the breaker. At the Koeberg 400kV GIS, the GasVue camera accurately located a leak on a feeder link compartment. While the station staff was aware that the compartment was leaking, GasVue pinpointed the location.

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

    Mar 20, 2013Due 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.
