Abstract :
Mineral oil is poorly biodegradable and has a low flash point. It does not satisfy the requirement of environmental sustainability and fireproofing. Whereas vegetable oil-based dielectric liquid is fully biodegradable and has a higher flash point and relative permittivity. This paper presents a type of insulating oil refined from a transgenic rapeseed oil. The oil-refining procedure is introduced. Chemical, physical and electric properties of refined insulating oil are presented. Influences of temperature and water content on the electrical breakdown voltage, relative permittivity, and dissipation facto of the refined oil are determined by experiments. Experiment results indicate the transgenic rapeseed oil based dielectric liquid possesses advantages over mineral insulating oil
