description: This work is devoted to the replacement of obsolete equipment for protecting transformers of the Leningrad NPPs own needs, made on the basis of electromechanical relays, with new microprocessor protections. The work considers exclusively domestic equipment for microprocessor protections within the framework of the import substitution policy, which is quite relevant at the present time. The import substitution policy is aimed at stimulating the domestic industry by reducing imports and increasing domestic production. The expected effect of upgrading the protection of auxiliary transformers at the Leningrad NPP: ensuring the reliability of the auxiliary power supply for power units No. 3 and 4, reducing labor costs for maintenance and repair due to the lack of need for additional adjustments, reducing weight and dimensions, combining protection, automation, control and monitoring functions in one device.
