Summary
This TB describes moisture equilibrium and migration in oil-pape rinsulated power transformers. It gives in-depth knowledge of the main sources of moisture contamination, the solubility of water in oils, the adsorption in the cellulose, the physical background for moisture equilibrium and bubble evolution. Practical advice for moisture determination via equilibrium diagrams and for migration time constants, and moisture measurement techniques are provided.
