SF6 Gas Insulated Switchgear(GIS) Manufacturers and ... SF6 load switch is sealed in a closed device filled with SF6 gas. Check the SF6 barometer to ensure that the air pressure is between 0.4 and 0.5Mpa. The pressure gauge will change with the change of external temperature.

Plant Engineering | Reducing arc flash hazard on switchgear· Upon startup of a transformer, a large magnitude transient current flows for several cycles that is many times the rated amperes of the transformer. The overcurrent protective device on the line side of the transformer must be able to ride through this inrush current. This hampers the ability of the protection system to reduce the arc flash energy.
