摘要：
Experiences in moisture contents assessment in paper-oil insulation of transformers with advanced ageing processes have been presented. It was found that joint measurement RVM+PDC increases quality of assessment, especially for transformers with non-homogenous morphology of insulation. For water contents in cellulose higher that 3% it is necessary to take into consideration for analysis results of oil tests. The measurement RVM+PDC after considering oil tests allows to identify deposits on the active part of transformers.
