Field drying of transformer insulation | T&D ... - Siemens USA transformer's life is determined by the health of the insulation system. If one tiny piece of the insulation in a critical location fails, electrically or mechanically, the transformer is potentially doomed. The estimated life of a transformer is calculated to be approx. 20.5 years (per IEEE C.57.91) minimum when operated as follows:
Gas-insulated Switchgear (GIS) Testing - OMICRON Switchgear (GIS) Testing. Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas.
