PROJECT TITLE :
An Updated Model to Determine the Life Remaining of Transformer Insulation
During this paper, we have a tendency to present an update to the models used to calculate the remaining life of transformer paper insulation. A downside to the current IEEE method is that it will not take into consideration the availability of water and oxygen on the life expectancy of Kraft paper insulation. We therefore set out to test an algorithm which does take these under consideration. For our investigation, we loaded 3 check transformers and ran them to close their finish of life. Kinetic equations were applied to model the fall in the degree of polymerization of paper. Our model showed higher agreement with the check results than that given from using the IEEE standard. The IEEE customary offers life expectancy for Kraft paper being aged in minimal oxygen underneath dry conditions, that isn't necessarily representative of an old transformer. Wet paper and using high levels of oxygen can age nearly 40 times faster. The IEEE methodology needs to require the synergistic result of water and oxygen on increasing the rate of paper aging into account.
