2013/3/20The working of SF6 CB of first generation was quite simple and it is some extent similar to air blast circuit breaker.Here SF6 gas was compressed and stored in a high pressure reservoir. During operation of SF6 circuit breaker, this highly compressed gas is released through the arc in the breaker and collected to a relatively low pressure reservoir and then it is pumped back to the high

SF6 (Sulphur hexafluoride) is a colorless, odorless, and non flammable gas with very low reaction chemistry. It is used as an insulator for high voltage circuit breakers, switchgear, and other electrical equipment. SF6 gas has high dielectric strength that allows for a significant reduction in the size of electrical equipment.

2021/1/29Using RC (Snubber) Suppression Paralle with the Load. Ohm's law is applied to choose the most appropriate resistor value for the arc suppression. In the Ohm's law R = V/I, we apply the formula R = 0.5 (Vpk / ISW) and R = 0.3 (Vpk / ISW), where Vpk is the AC peak voltage ( 1.414 Vrms) and ISW is the rated switching current of the relay contact).
