description: The work is devoted to the study of the problem of differential protection in transient modes and ways to improve the reliability of its operation. Tasks that were solved during the research: 1) various braking algorithms in static and dynamic modes are analyzed; 2) a model of a power transformer reproducing transients has been created, the signals of the received transients have been analyzed; 3) methods of modeling a current transformer are described, signals in dynamic modes with different models of current transformers are analyzed; 4) a laboratory stand has been assembled to remove signals from the current transformer, one of the models of the current transformer has been verified using the stand; As a result, based on the data obtained, a list of recommendations for the development of new relay protection algorithms has been compiled, following which will help to increase the reliability and sensitivity of transformer differential protections.
