In order to reduce the GIS-related global warming impact, innovative solutions using alternative gases have been developed by different manufacturers, especially the blue GIS from Siemens ¨C available for 145 kV / 40 kA / 3150 A ¨C with clean air insulation and vacuum switching technology shows many technical advantages %K High voltage gas-insulated switchgear %K GIS %K vacuum interrupter %K clean air %K SF6 alternatives %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=332264
