SF6 Air Sensor Trader for Very High Voltages

SF6 Air Sensor Trader for Very High Voltages

One typical switchgear design, the gas-insulated switchgear, uses a refrigerant gas, sulfur hexafluoride (sf6 gas), as an insulator.Owing to its very large dielectric constant, sf6-gas, is a very good insulator and so it has found widespread use in switchgears that need very high voltage handling capabilities. 1 It is very chemically inert and
