Sulfur Hexafluoride MV switchgear for High Speed Rail

Sulfur Hexafluoride MV switchgear for High Speed Rail

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...
