FORMATION OF METHANOL UNDER ACCELERATED AGING OF PAPER INSULATION IN TRANSFORMER OIL
AbstractThis paper depicts test results of methanol formation appearing in paper insulation accelerated aging in transformer oil under temperature influence. All studied materials (cable insulation paper, transformer oil) are manufactured in Russia Results of cable paper К-120 accelerated aging in transformer oil ГК will be presented at the end of this report. The dependence of methanol concentration versus the degree of polymerization of paper insulation, obtained by the authors, have been compared with dependence gained by English and French researchers and may become the basics of paper insulation remaining lifetime estimation, as so for, remaining lifetime of power transformers.
