description: Technical solutions of reliability assurance are proposed in this project.First of all the steady-state operating mode of the system is calculated and analyzed. The short-circuit currents are calculated in the RastrWin software package. Existent protections of autotransformers are researched. Primary and secondary protections of autotransformers are chosen based on terminals of EKRA developer. Calculated settings of differential, distant, and current protections. The sensitivity of these types of protections and its compliance with the requirements have been tested.Provided compliance tests of current transformers, which supply protections.Settings calculation and sensivity tests performed based on calculations, performed by graphoanalytic method with program complex RastrWin.
