Substations SF6 circuit breakers: Reliability evaluation

However, this development uses, as an example, real data from SF6 circuit breakers installed in a transmission substation and operating practice in Brazil. SF6 gas has an excellent property of arc extinguishing; its time of extinction is, nearly, one hundred times faster than air, under similar conditions . Therefore, this gas is widely used in
