Future of sf6 gas in Switchgear in Europe | Power Technology Research

Paris AgreementEuropean Commission F-Gas RegulationsRegulation (EU) 517/2014Why Commission’s Report Did Not Take Strong Stance?sf 6 AlternativesMoving ForwardThe Paris Agreement was a landmark agreement with a global agenda to combat climate change. Following its announcement, the electrical industry has focused on playing its role in the reduction of carbon footprint. A greater push towards renewable energy sources was their natural response but fossil fuel-based electricity generation is not the only aspect of industry which has detrimental impact on the environment. Utilization of SF₆ in electrical switchgear also contributes to global warming and is a hazard specially in long term. In response to the threat along with other technological improvements, alternatives of SF₆ have been introduced in last few years subsequently ushering in an era of green switchgear. But despite the introduction of alternative technology, sf 6 still remains the most widely used solution in the market.Get price

Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas
