Abstract
In this article we explain how acids are formed in the oil and in paper insulation and their involvement in paper degradation. The acidity of the oil reached at the end of a number of paper-aging experiments is reported, and relationships between it and temperature, moisture, oxygen, degree of polymerization (DP), and aging time are presented.
