SF6 is certainly no SF6 is used in wind turbines: TRUE. SF6 is used not in the turbine itself, but in There are no viable alternatives to SF6: PARTLY FALSE. Bodies including See full list on phys.orgPanel discussion: The pros and cons of using SF6 gas in ee.co.za/article/panel-discussion-pros-cons-using-sf6...14/07/2015As the quantities that leak from the switchgear are low, the contribution to the greenhouse effect can be considered extremely minimal to affect climate changes. Nevertheless, there are toxic by-products that are produced in SF 6 during arcing. Hence SF 6 leakages can become dangerous when leaked in large concentrations. However, if leaks happen in an open space, the concentration will be diluted and effects
