It has become an imperative case on seeking the substitute of SF6 for its severe greenhouse effect in recent years, not only for scientists but also the electricity sectors. CF3I, as a substitute gas for SF6 with lower Global Warming Potential (GWP), has been investigated. The use of pure CF3I in gas insulated switchgear (GIS) and gas insulated metal enclosed transmission line (GIL) is difficult because...
Oil-immersed transformer is the main equipment of power system operation, whose insulation aging research has been a topic that deserves attention. In this paper, based on the self-developed thermal aging oven, the pure oil sample and those of 3 kinds of different oil-immersed material (paper, Polycarbonate, Polyester) were aged under three different temperature (90°C, 110°C, 130°C) for accelerated...
