  • Gas-insulated Switchgear (GIS) Testing - OMICRON

    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. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS.

  • Gas density monitor - GDM-100 - WIKA USA

    Description. Gas density is a crucial operating parameter for high-voltage equipment. If the required gas density is not present, safe operation of the plant cannot be guaranteed. The WIKA gas density measuring instruments provide reliable warnings against dangerously low gas levels, even in extreme environmental conditions.

  • Switchgear - Wikipedia

    In 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.

  • Substations - an overview | ScienceDirect Topics

    One substation, in particular, faces a threat of demolition by neglect. The Washington Park Substation at 6141 S. Prairie Avenue is an outstanding example of the many substations constructed across Chicago. This substation is larger than most as it was meant to distribute higher voltages to other substations.

  • Measuring partial discharge in GIS | Think Grid

    To overcome this constraint, a parallel technology was developed, the Gas-Insulated Substation (GIS), using a gas, for example sulphur hexafluoride (SF 6), at high pressure. SF 6 has excellent dielectric properties and is used as the insulating medium between the phases and between the phases and earth. As a consequence, a GIS is much more compact.

  • GIS | High-Voltage Gas Insulated Switchgear Substations

    Gas Insulated Substations . A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible.
