Sulfur hexafluoride (SF6) Circuit Breaker: Types & How It Works
An SF6 circuit breaker is a protective device that uses sulphur hexafluoride gas as an arc quenching medium. It is the type of circuit breaker used to protect power systems, electrical grids, and distribution stations. SF6 gas has strong electronegativity and arc quenching properties, making them a better insulating medium than air and oil circuit … Read more
