Abstract
In this study thermally upgraded kraft paper was degraded in insulating oil in accelerated conditions, at different temperatures. In our aging method the paper was heated from 100 to 400 °C but the mineral insulating oil temperature was maintained below to 60 °C, to avoid oil aging. Dissolved gases were analyzed (DGA) and other cellulose thermal byproducts that result from the process were also determined in order to build a new tool to help diagnose incipient thermal faults involving insulating paper.
