high voltage sf6 mixture insulation System
2011/11/17When switching is done in a SF6 Gas insulated switchgear, arching will occur. This is because there is a high impedance on the breaker switch when the switch is opened and high voltage current tries to flow through the impedance. The arching release immense heat and SF6 gasses will quench the arching in order to prevent it from spreading.

252kV sf6 gas Equipment Activity
252kV sf6 gas Equipment Activity2017/8/243. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.

Sulfur hexafluoride is pretty awesome.It is a gas six times denser than regular air, and thus you can actually make tinfoil "boats" float on it. It also makes your voice deep when you breathe it in. Let's have a sea of it. To prevent the entire planet from becoming a barren wasteland, make it a single sea about the size of the Black Sea, with an island the size of Cyprus in the middle.

railway Arc extinguishing explainThis arc is dangerous on account of the energy generated in it in the form of heat which may result in explosive force. The circuit breaker should be capable of extinguishing the arc without causing any disturbances to the equipment or danger to the personnel. The arc plays a vital role in the behaviour of the circuit breaker.
