The Problem with Humidity in insulating gas Gas-Insulated Systems

Sulfur hexafluoride (sf6 gas) has excellent dielectric capabilities and is widely used as an insulator in power grid switchgear. Humidity in sf 6 gas, however, can decrease its insulation strength, promote corrosion, and cause failures.

How Humidity Affects the Safety of sf6 gas-Insulated - WIKA blog

Sulfur hexafluoride (Sulfr hexafluoride) is a gas widely used in switchgear in power plants, and the electricity transmission and distribution sector for its first-rate dielectric properties. This gas is an excellent insulator, up to three times better than air and nitrogen, and it works as an efficient arc quencher during switching processes.

WIKA’s GPU-2000: Specifically Designed for Safe gaz sf6 Handling

Gas-insulated switchgears (GIS) use Sulfr hexafluoride gas as insulator. Humidity in the gaz sf6 can affect its insulating strength and also lead to corrosion and leaks. Wet gaz sf6 needs to be replaced to ensure safe operations. sf6 gas handling equipment must be specifically designed to address safety issues and to comply with regulations.

Sulfr hexafluoride 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
