go to the Gas-insulated switchgear product page Tim asked on Mar 11th, 2015 in Gas-insulated switchgear

Can I keep my GIS bay energized even if the SF6 pressure in a gas compartment is at ambient level (1 bar) ?

Due to a leakage, the SF6 density in one gas compartment decreased quickly and I wonder, if I have to de-energize the GIS immediately or can still keep it on-line until I have an engineer on site to fix it.

ABB's answer

No. All GIS gas compartments must have at least “minimum functional density”. If the density goes below minimum functional density the concerned gas compartment must be switched off immediately.
