Advantages of a Gas Insulated Substation (GIS)
Session
Energy Efficiency Engineering
Description
Electricity represents the main form of energy, necessitating its transmission through the grid's transmission lines to reach various distribution network nodes. In Kosovo, the transmission lines function at voltage levels of 110 kV, 220 kV, and 400 kV, whereas in Europe, certain transmission lines are equipped to handle higher voltage capacities. Furthermore, medium voltage distribution lines operating at 35 kV and 10 kV are dedicated to serving large-scale consumers, while the low voltage distribution system, up to 0.4 kV, is specifically designed to supply power to commercial and residential customers. To meet consumers' electricity consumption demands, appropriate voltage levels, as mentioned above, are established through the use of ascending or descending substations. This paper offers a concise introduction to the Gas Insulated Substation (GIS) system. A GIS is a high voltage substation wherein the primary conducting structures are enclosed within a sealed environment, employing SF6 (sulfur hexafluoride) gas as the insulating medium. This paper begins by presenting the general characteristics of substations and subsequently delves into the fundamental concepts of GIS systems. Finally, it extensively explores the implementation of the GIS system in SS 110/10(20) kV - Pristina VI, emphasizing its significance and highlighting the distinctions between the GIS and Air Insulated Substation (AIS) systems.
