Abstract :
Three types of edible natural ester oils (soya, rice and sunflower) were aged with and without antioxidant additives. The properties of these aged oils were analyzed in comparison with a commercial natural ester insulating product (Biovolt A). Dissolved gases in these aged oils under thermal and electrical stress were also investigated.
