sulphur hexafluoride quality Schneider

The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.

    Sulfur hexafluoride (SF6) is an inert, volatile tracer and has been deliberately added to water bodies to determine kw. Experiments in enclosed lakes showed a good correlation between kw and wind speed and a parameterization of kw developed from these studies predicts a similar global mean (12 cm h −1) to that obtained from the radon data.
