The technological process of manufacturing of a power transformer is considered from the point of view of the effect of carrying out technological and control operations on the distribution of the resource of the transformer. The purpose of this work is to develop a methodology for assessing the influence of the manufacturing quality of a power transformer on its designated life. Estimation of the residual service life of the active part of the power transformer at various stages of its life is an actual scientific and technical task. The apparatus of the algebra of fuzzy numbers is applied for developing models of decreasing of transformers resource. Models are proposed for assessing the influence of the technological process stage on the assigned resource. The proposed models differ due to the imperfection of the means of control and the stochastic nature of the process of changing the resource in the course of the technological process. The developed models can be used to calculate the residual resource of a power transformer when designing or operating it. Further research will be aimed at developing a computer model of the mutual influence of the life cycle stages of a power transformer on its resource consumption.
