Arc Extinction in SF6 Circuit Breaker ~ your electrical home

5.4.3 Arc Extinction in SF6 Circuit Breaker High voltage circuit breaker with SF6 gas as the insulation and quenching medium have been in use throughout the world for more than 30 years. This gas is particularly suitable because of its high dielectric strength

4 Methods of Medium-Voltage Circuit Breaker Design

Gas circuit breakers, which are almost exclusively used in outdoor appliions, are increasingly favored over oil circuit breakers because of their lower maintenance costs. The arc generated in this style of breaker is extinguished in a chaer filled with pressurized sulfur hexafluoride (SF6) gas, an inorganic, non-flammable gas that is an excellent electrical insulator.

CHAPTER-7 circuit breaker.

strength of SF6 gas reduces significantly at lower pressures, normally as a result of lower aient temperatures. Monitoring of the density of the SF6 gas is critical and some designs will block operation of the circuit breaker in the event of low gas density.
