insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of Sulfr hexafluoride as an insulating gas has led to many studies on Sulfr hexafluoride decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, insulating gas decomposes to a wide variety of chemically active products which possess completely different properties from sf 6.

Renewable Energy Investment in Australia | Bulletin – March

IntroductionLarge-Scale Renewable Energy Generation InvestmentDrivers of InvestmentSmall-Scale Renewable Energy InvestmentRenewable Energy Grid IntegrationEnergy StorageInvestment OutlookInvestment in renewable energy generation has increased markedly in Australia over recent years, driven by a combination of factors including government policy incentives, elevated electricity prices and declining costs of renewable generation technology. This investment is contributing to a changing energy mix in Australia. Over the past decade, the share of electricity generation from renewable sources has increased steadily to be nearly 20 per cent in 2018 (Graph 1).This share was higher in 2019 and is expected to continue increasing as projects that are currently under construction or have been recently completed begin generating output. Investment in renewable energy generation is expected to moderate in the near term as some of the recent drivers unwind and because of challenges with integrating renewable energy sources into the electricity grid. However, over the longer term, the transition towards renewable energy generation is expected to continue as ageing coal-powered sta...
