Moisture has a significant effect on the dielectric strength of paper insulation used in the
transformer. Variation of moisture in paper insulation accelerates the ageing process of
cellulose, degrading the insulating properties of the paper. As a result, the failure of the
transformer occurs to leading catastrophic losses in the whole electrical power system. This
paper describes a method to determine the moisture content of insulation paper at
laboratory environment based on the change of the refractive index of insulation paper due …

Moisture has a significant effect on the dielectric strength of paper insulation used in the transformer. Variation of moisture in paper insulation accelerates the ageing process of cellulose, degrading the insulating properties of the paper. As a result, the failure of the transformer occurs to leading catastrophic losses in the whole electrical power system. This paper describes a method to determine the moisture content of insulation paper at laboratory environment based on the change of the refractive index of insulation paper due to the variation of moisture in it. Influence of temperature on the cellulose paper material has been considered in the experiment for the proper estimation of moisture in the paper insulation.
