sf 6 Decomposition in Gas-Insulated Equipment - IEEE Journals

This paper reviews previous research in sf6 gas decomposition relating to the operation of gas-insulated switchgears, gas-insulated transmission lines, and electrostatic accelerators. Results on the qualitative and quantitative determination of the by-products and their formation ion rates in various modes of electrical discharges are summarized. The mechanisms leading to the formation of transient and stable products are described.Get price

Erosion risk assessment for Uganda and Kenya - A sensitivity

Soil erosion by water poses a serious risk for land degradation in Sub-Saharan Africa. To mitigate soil erosion, it is imperative to identify areas with high erosion potentials and to quantify the soil erosion. The Revised Universal Soil Loss Equation (RUSLE) is a standard model to assess the soil erosion risk. The RUSLE quantifies soil loss as the product of six input factors representingGet price

Exploring Janus MoSSe monolayer as a workable media for SOF6

Jan 01, 2021 · The adsorption energy of SF 6 decomposition components (i.e. H 2 S, SO 2, SOF 2 and SO 2 F 2) on MoSSe monolayer is defined as the difference between the sum of the energies of an isolated molecule and the monolayer and the total energy of the molecule adsorbed system, as the following expression, (1) E ads = E suf / gas-E suf-E gas, where E suf / gas and E suf are the total energies of the optimized ground state of MoSSe monolayer with and without molecule adsorbed on, respectively.Get price
