NCIT Technology in Gas Insulated Switchgear - World design results in a reduction of GIS dimensions, as well as environmental benefits due to the reduction in the volume of SF6-insulating gas in switchgear. Another important point is the reduced engineering and logistics of non-conventional instrument transformers due to NCIT mounting partition; this is integral to the GIS itself.
Switchgear - Wikipedia an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.
