Statement of the problem of multipole modelling of wear processes of cellulose insulation of a power transformer

Year: 2024

Type: article

Abstract: An important area of theoretical research is the mathematical modelling of the state of cellulose insulation, which determines the life of a power transformer Predicting the state of cellulose insulation requires computer modelling. The known mathematical models for predicting the aging of cellulose insulation have drawbacks. Therefore, it is necessary to formalise the task of multipole modelling, select a multipole modelling tool and review the literature on models (concentrated, layered, etc.) and select a multipole modelling tool (FEMM, etc.). At the same time, there are issues that need to be addressed/clarified, such as such as the factor of the applied force to the cellulose insulation at the moment in time. Therefore, it is necessary to develop a new mathematical model and move to the use of field models.
