摘要：
Since SF6 gas has been specified as one of the greenhouse gases, we attempt to develop new insulation gases or gas mixtures alternative to SF6 gas for gas insulated switchgears (GIS). In this paper, we investigated partial discharge (PD) and breakdown (BD) characteristics of CO2 gas and CO2 gas mixtures as one of the promising candidates without using SF6 gas. Experimental results revealed PD inception and BD strengths for different gas pressure and CO2 content under lightning impulse voltage and ac high voltage application.
