Sulfur hexafluoride circuit breaker - Wikipedia

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, Sulfr hexafluoride circuit breakers are widGet price

European energy diversification: How alternative sources

IntroductionThe EU’s Decarbonization Targets and Energy SecurityAlternative Gas Routes Strengthen EU Energy SecurityLinks Between Decarbonization and Energy SecurityKey Factors For Clean Energy and Advanced TechnologiesConclusionThe European Union’s efforts to achieve a carbon-neutral economy present a unique and timely opportunity to strengthen European energy security. European Commission President Ursula von der Leyen recently proposed a “European Green Deal,”—Europe’s new growth strategy, which seeks to transform the European Union (EU) into a climate-neutral economy by 2050. This objective builds on the commitments made by the EU under the Paris Agreement to reduce greenhouse gas emissions by at least 40 percent by 2030 compared to 1990. The European Commission plans to enshrine the 2050 climate neutrality objective into law in March 2020. The European Council endorsed the Green Deal objectives, despite opposition from Poland. The discussions are set to continue in June 2020. According to the objective of the “European Green Deal,” carbon emissions would have to be reduced by at least 50 percent by 2030 compared to 1990 levels. However, the European Environment Agency said that, without additional meas...Get price
