The assessment of alternative insulating gases usage for HV distributional equipment with the aim on lowering the environmental impacts

The presented paper deals with the various possibilities of insulating gases designed as an insulating blend for high voltage distributional switchgear and equipment. The technical superiority of sulfur-hexafluoride is discussed with its environmental disadvantages and limitations. Alternative gases as SF6 replacement are introduced and their usage is discussed. The paper concludes with the system operator’s best-practices with the alternatively insulated equipment
