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
