Abstract

This paper is aimed at evaluation about aging properties of cellulose paper used for insulating of oil-filled transformer and analysis on correlation between mechanical characteristic such as tensile strength and chemical characteristics such as CO, CO₂ gas and furfural when cellulose paper is aged by thermal. For experiment the accelerated aging cell has been manufactured, it has been aged during 60 hours at 100, 150, 180 and 200[°C], respectively. It has been used DGA(dissolved gas analysis) and HPLC(high performance liquid chromatography) for degradation diagnosis. Also it has been established correlation between them using multiple regression analysis.
