Evaluation of moisture content is important as a measure of the insulation undergoing electrical and mechanical stress which may in turn decrease the life expectancy of the transformer. The content of moisture in the insulation is dependent on many factors like; aging, temperature, cellulose material, transformer design, operating conditions, conservator system etc. Moisture content in insulation to transformer age is approximated to vary exponentially and is classified by the presence of moisture as dry and wet. Flow of electrification, dielectric strength and transformer insulation degradation are the main issues due to moisture affecting transformer health. So it is important to study various methods used for the estimation of water content in the insulation material. In the present communication different methods are reported for evaluating this fundamental property of insulating materials. Nevertheless, these test methods differ, depending upon the procedure, design of transformer, different insulating materials used, analyzed on various types of different specimen samples and fluids used for insulation.
