Popis:	This work presents the testing of a unique composite gaseous insulating material using comparative evaluations with the properties of existing insulating materials. Main objectives of this research include the investigation of a novel composite insulating material with superior insulating properties, reduced cost, and less environmental hazard. Sulphur hexafluoride (SF6) is commonly used in current electrical insulation network but having recognised disadvantage of global warming potential (GWP) 23,800 times larger than CO2. Due to this, it is an urgent need to find alternative of SF6 which is environment friendly. R12 and its mixture with different concentration of carbon dioxide with varying pressure are tested. Gaseous mixtures containing R12 gas demonstrate good dielectric properties with low-temperature usage possibilities. The insulation properties of SF6 and R12/CO2 gas mixtures with other merits and experimental set up are comprehensively discussed in this paper. The experimental study of power frequency breakdown voltage is also analysed for a proposed gaseous mixture of R12/CO2.
