Moisture equilibrium characteristics of oil-paper insulation systems are important for insulation condition evaluation of oil-filled transformers. This paper presents moisture equilibrium curves of mineral and vegetable oil-paper insulation systems obtained by both direct and indirect methods. A new mathematical model is proposed to determine moisture content in oil-paper insulation systems. Experiments...
Taking sealed boxes as the research object, the author analyzes the main source of its moisture content. Based on the permeability mechanism of the sealed boxes and the moisture mechanism of the items inside the boxes, the paper establishes the mathematical model of the relative humidity inside changing over time, applying MATLAB to make a simulation analysis of the mathematical model. The simulation...
