Abstract
This article discusses about the differences in results from an experiment that was performed on ageing of thermal upgraded Kraft (TUK) insulation system with mineral oil and ester liquids under different pressure conditions. When sealed tube ageing studies are conducted as per the IEEE C57.100 test standard, there are no requirements per the standard on the type of ageing vessels to use or the pressure limits. The experiment was conducted using metal vessels and glass vessels with pressure relief devices installed to control the pressure during ageing. The results from the ageing test showed that controlling the pressure in the ageing vessel does affect the rate of acceleration of the solid insulation and the ageing rate of TUK is slower in esters in comparison to mineral oil.
