How much you know about SF6 circuit breaker

Due, to the superior arc quenching properties of sulphur hexaflouride gas (SF6) gas, the sulphur hexaflouride gas (SF6) circuit breakers have many advantages over oil or air circuit breakers. Some of them are listed below :

Due to the superior arc quenching property of sulphur hexaflouride gas (SF6), such circuit breakers have very short arcing time.

Since the dielectric strength of sulphur hexaflouride (SF6) gas is 2 to 3 times that operation due unlike of air, such breakers can interrupt much larger currents.

The sulphur hexaflouride gas (SF6) circuit breaker gives noiseless operation due its closed gas circuit and no exhaust to atmosphere unlike the air blast circuit breaker.
