In this paper, we studied the feasibility of replacing SF6 with CF3I/N2in terms of power frequency breakdown performance under the influence of gas pressure, mixing ratio, and electric field. The synergistic effect, liquefaction temperature, and self-recover ability of CF3I/N2were analyzed. Density matrix - Frustrated Heisenberg model

Gas-insulated switchgear without SF6 | Credible Carbon

Gas-insulated switchgear without SF6 . National Grid, wong with GE Grid Solutions and 3M, has commissioned the world’s first gas-insulated switchgear using an alternative to sulphur hexafluoride (SF 6).Used around the world for decades, SF 6 is a powerful insulation gas that allows high voltage electricity switchgear to take up less space. However, while leakage rates are extremely low

SF6 Gas Density Monitoring | TRAFAG

Unique SF6 monitoring: Coined mechanical AND electronic monitoring. The Hybrid Gas Density Monitor coines the advantages of both the mechanical gas density monitorand the electronic gas density sensor in a compact all-in-one apparatus: With its analogue or digital output it is the ideal gas density monitor for smart online SF6 gas management systems.

Gas density monitors -

Gas density monitors from are fitted with up to three alarm contacts and reliably warn in advance of dangerously low gas levels. The monitoring of SF6 gas density in medium and high-voltage switchgear can thus be left to secondary technology. Our gas density monitors are hermetically sealed and temperature-compensated.
