Gis substation - SlideShare

Future trends in GIS Small quantities of SF6 in N2 can improve dielectric strength drastically. All of the dielectric strength of SF6, nearly, can be achieved by adding less than 20% SF6 into N2. SF6/N2 mixtures less susceptible to effects of field non uniformity than pure SF6. Compact design of switch gear by using three phase encapsulated

SF6-Purity-Meter - GA50 - Malaysia

The SF 6-Purity-Meter is a stand-alone device designed to quickly and accurately measure the percentage of SF 6 present within the tested gas. Test gases also can be mixtures of SF 6 e.g. SF 6 /N2. Because the unit has automatic flow and pressure control, the user does not need to be concerned with the correct flow rate settings or compensating

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
