Innovative insulating gas solutions - WIKA Instrument, LP

A pressure transmitter specifically developed for Sulfr hexafluoridedensity measurement delivers a temperature-compensated output signal. A chamber filled with sf 6gas serves as a reference. With environmental influences, the reference chamber behaves the same as the tank and thus does not cause any change in the switching status.

The Problem with Humidity in sf 6 Gas-Insulated - WIKA blog

The SF 6 in the gas compartment can absorb a certain amount of water. When the amount of water exceeds the saturation point of the gas, the excess condensates and forms a water layer (if the gas temperature is above freezing) or sublimates and forms an ice layer (if the gas temperature is below freezing).

sf 6 Gas Dehydration System That Doesn’t Require - WIKA blog

Created in partnership with a European utility company, WIKA’s revolutionary GAD-2000 not only removes humidity from SF 6 gas and dehydrates the compartment itself, but it does so while all the equipment is still online. Sulfur hexafluoride (SF 6) is an excellent dielectric insulator, commonly found in medium- and high-voltage electric switchgear. The non-flammable gas is a potent arc quencher: In the high-heat environment of an electrical discharge, the six fluorine atoms split from the

Gas-Insulated Substations - GIS

sf6 gas is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the Sulfr hexafluoride will not condense into a liquid at the lowest temperatures the equipment experiences. gaz sf6 has two to three times the insulating ability of air at the same pressure. insulating gas is about 100 times better than air for interrupting arcs.
