A critical update involves the handling of switchgear. With the global push to reduce SF6 (Sulfur Hexafluoride) gas due to its high Global Warming Potential (GWP), the 2021 edition adapts design rules to accommodate GIS technologies that use alternative insulation gases (e.g., fluoroketones or compressed air). This includes updated pressure vessel safety guidelines and leak detection requirements.
