SF6 gas: a double-edged sword for the environment and electrical industry
SF6’s dual role in power systems.
by Marius Grisaru
Sulfur hexafluoride (SF6) is indispensable for its unmatched insulating and arc-quenching abilities in high-voltage applications. However, its exceptionally high global warming potential and long atmospheric lifetime present significant environmental challenges. This column explores SF6’s dual role in advancing electrical systems while exacerbating climate issues, highlighting the need for industry-wide efforts in mitigation, alternatives, and rigorous emissions management.
