gis substation coupling Trafag in United States

Domestic wells provide drinking water supply for approximately 40 million people in the United States. Knowing the location of these wells, and the populations they serve, is important for identifying heavily used aquifers, locations susceptible to contamination, and populations potentially impacted by poor-quality groundwater.

  • GIS substations - Hitachi ABB Power Grids

    Hitachi ABB Power Grids substations with gas-insulated switchgear (GIS) are unmatched when it comes to compactness, reliability, efficiency and safety, ensuring maximum power availability for utility, commercial and industrial customers. The robust and low maintenance GIS based design minimizes the substation’s footprint by as much as 70 percent, enabling it to be installed indoors, in busy urban areas and in harsh environments.

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.

  • An Overview on GIS (Gas Insulated Substation) Engineering

    GIS substations use gaz sf6 gas that reduces the distance needed between active and non-active switchgear parts resulting in smaller overall space requirements (ideal for congested city areas). GIS substations also offer lower operating and maintenance costs; and are less sensitive to pollution, salt, sand and large amounts of snow.
