  • SF6: No Leak Too Small | TD World

    The Trafag gas monitors do not have any control function on the breakers to isolate sections of the GIS; instead, they only supply both a low and low-low alarm indication. The theoretical design limit of the GIS bus and breakers is that at zero SF 6 pressure, the components insulation systems will withstand 1.0 per unit line-to-ground voltage. Throughout the design process, this fail-safe philosophy was employed
