Environmental Effects of Electrically-Stressed Sulfur

Abstract. High Voltage (HV) equipment such as power switches, current or voltage transformers, and flexible HV transmission lines insulated by pressurized SF6 (or SF6/N2 mixtures) offer component compactness, high reliability and low maintenance demands compared to all conventionally insulating components (i.e. air, organic solid insulants, and mineral oils).

Wide Carbon Nanopores as Efficient Sites for the

SF 6 and SF 6-N 2 mixed gases are used widely as insulators, but such gases have high greenhouse gas potential. The separation of SF 6 from SF 6-N 2 mixed gases is an inevitable result of their use. Single-walled carbon nanohorns (CNHs) were used here for a fundamental study of the separation of SF 6 and N 2.The diameters of the interstitial and internal nanopores of the CNHs were 0.7 and 2.9

N2/SF6 gas Mixtures — Large Scale Appliion in Gas

Abstract. The appliion of N 2 /SF 6 gas mixtures with SF 6-contents between 10 % and 20 % reduces the costs for the insulating gas remarkably.This is of great importance when GIL is to be used for long distance bulk power transmission. By this, also the acceptance for long distance appliions of this technique is improved on the user side.

Breakdown voltage characteristics in the SF6/N2 gas

The SF6 gas insulated switchgear (GIS) is the electric power equipment for transmission and distribution line which reduced the size of the electric power equipments by installing in a sealed tank. Since the size of the GIS is about 1/10 of the air insulated switchgear, high quality insulation gas should be used. However this gas is a source of global warming and its production cost
