Various aging processes in a paper-natural ester insulation system in the presence of copper and moisture

This article adds more information to the problem of natural ester use as an electroinsulating uid in cellulose paper-oil systems, e.g., for use in power transformers. An accelerated thermal aging (120, 140 and 160 C) of samples consisting of cellulose paper (transformerboard), a t...
