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.[email protected]
On-site low frequency heating (LFH) drying optimized drying the transformer should be heated at the same time as vacuum is applied (as is done during the vapor phase process). With the combination of the low frequency heating (LFH) technique and hot oil spray or hot oil circulation, this can also be achieved on-site.Get Price
Gas-Insulated Switchgear | High Voltage Experts Insulated Switchgears and substations (GIS) were designed to overcome the limitations of air and oil insulated power systems.
