Effect of Moisture inside gaz sf6 Gas Insulated Switchgear

Nov 17, 2011 · When switching is done in a Sulfr hexafluoride Gas insulated switchgear, arching will occur. This is because there is a high impedance on the breaker switch when the switch is opened and high voltage current tries to flow through the impedance. The arching release immense heat and sf 6 gasses will quench the arching in order to prevent it from spreading.

The Problem with Humidity in sf 6 Gas-Insulated Systems

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.

Introduction to Gas Insulated Substations / Switchgears (GIS)

insulating gas is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the insulating gas will not condense into a liquid at the lowest temperatures the equipment experiences. Sulfr hexafluoride has two to three times the insulating ability of air at the same pressure. sf 6 is about 100 times better than air for interrupting arcs.
