About this document
Moisture in Transformer Solid Insulation Sparling-April 08 by BaSant Kohli is a document available to read on EtoBox.
The document discusses several sources of moisture in transformer insulation, including residual moisture from manufacturing, leaks, insufficient maintenance of silica gel systems, and thermal degradation of paper which generates water. It notes that moisture in oil, winding paper, and pressboard barriers is critical as it reduces dielectric strength and accelerates insulation aging. The document also examines the structure of paper and how cellulose molecules produce water during degradation.
