description: Topic of the final qualification work: "Methods for monitoring the parameters of power transformers in transient mode". This work is devoted to the creation of methods for monitoring the parameters of the transformer with the aim of early detection of turn short circuits. Tasks that were solved in the course of the study: Development of a model of a power transformer with the possibility of observing turn short circuits. Creation of a laboratory stand with the ability to measure the instantaneous values ââof currents and voltages of the transformer. Development of methods for calculating the parameters of a transformer based on a T-shaped equivalent circuit. As a result of the work, a model of a power transformer was created with the ability to configure the magnetic circuit and switch to the turn-to-turn circuit mode, an experimental layout was assembled that allows measuring the values ââof electrical quantities in real time, 3 options for calculating the parameters of the transformer based on minimizing the objective error function were proposed. The operation of the selected method for identifying parameters in various modes of operation of the external network is analyzed, and an assessment of accuracy and stability is made.
