VALIDATION METHODS OF SF6 ALTERNATIVE GAS

gases for gas proportion corresponding to -15°C conditions. That means the gas mixture has no liquefaction from high temperature down to -15°C. For lower temperatures part of the gas is liquefied, and as a consequence dielectric performances are reduced. Alternative gas …

Light emission from corona discharge in SF6 and SF6/N2 gas

Light emission from corona discharge in SF6 and SF6/N2 gas mixtures at high pressure: Authors: gas mixtures has been undertaken using an optical multichannel analyser (OMA). A point-to-plane geometry has been used with point radii varying from 3 to 10 μm. Spectra are measured for high pressures ranging from 0.2 MPa up to 1.4 MPa and for

Breakdown Characteristics of SF6/CF4 Mixtures in Test

breakdown voltage of SF6/CF4 mixtures as add CF4 gas to SF6 gas (0.1MPa). All SF6/CF4 mixtures which have SF6 gas of 0.01MPa satisfied the standard of 25.8kV GIS in power frequency withstand voltage test. Mixed gas of SF6 (0.01MPa) and CF4 (0.01~0.06MPa) show more good dielectric characteristics than pure CF4 gas (0.2MPa) in impulse and

Development of the SF6/N2 Gas Mixture Insulated

Abstract. SF 6 gas found its use in China as an insulating medium in 1971 when Xi’an High Voltage Switchgear Research Institute developed the first Chinese GIS rated 110kV for a hydroelectric power station. in 1975 Xi’an Electric Power Capacitor Factory and Xi’an Jiaotong University jointly developed the first 500kV SF 6 gas-insulated standard capacitor in China. and as an extension of
