Gas Insulated Switchgear Transfer hipot

Abstract: Temperature rise of gas insulated switchgear (GIS) has to be limited according to the demands of the IEC 62271 standard. Computational methods for temperature rise are essential during the design of GIS. The heat in GIS is mainly transferred by convection, as the used insulating gas sulfur hexafluoride (sf6-gas)
