  • Introduction to Gas Insulated Electrical Substations

    Credits: 3 PDH

    PDH Course Description:

    This course provides an overview of (GIS) or Gas Insulated Substations. A gas insulated substation (GIS) is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as SF6, or sulfur hexafluoride gas as the insulating medium.

    In comparison, a conventional (AIS) or Air-Insulated Substation, uses atmospheric air as the dielectric gas medium, as these types of substations are almost always located at outdoor locations.

    Topics:

    • Overview of a GIS System
    • Hybrid GIS Substations
    • Advantages and Disadvantages of GIS Systems
    • SF6 gas, leak detection, and gas monitoring systems
    • Physical arrangements used in GIS
    • International Standards on GIS
    • Economics of GIS vs AIS
    • Contaminants and Oxidation in the Gas
    • Enclosure Modules for a GIS System
    • Conductors in a GIS System
    • Circuit Breakers and Transformers used in GIS Systems
    • Switching and Arrester Devices used in GIS Systems
    • Connections in a GIS Systems
    • The Control System of a GIS
    • Testing and Installation
    • Operational Procedures for a GIS
