The reconstruction of the Nadym 220 kV substation, the nodal power center of the Yamalo-Nenets Autonomous District, has begun. A package of digital technologies will be implemented here, including optical instrument transformers. The total volume of investments by Rosseti FGC UES amounts to 488 mn rubles. The work will be completed in 2021. The project will improve the reliability of energy supply to the region's consumers, including production facilities of Gazprom. The risk of human errors will be minimized and operational technical control costs will be reduced.

It is planned to install 12 Russian-made optical current and voltage transformers at the substation. Replacement of analog equipment with digital devices will enhance precision of measurements by at least 20%, which will reduce power losses and improve the quality of energy supply service. As these transformers are oil-free, fire safety will be improved. It will be possible to reduce the need for secondary equipment (inverters in the data acquisition system, communication lines).

The Nadym 220 kV substation will be the first trunk network facility in Yamal where this equipment will be installed. In 2018, similar solutions were applied to the construction of the Tobol 500 kV substation in the Tyumen region, which became Russia's first integrated digital ultra-high voltage class power facility.

Also, new microprocessor-based protections will be installed at the Nadym 220 kV substation to increase the speed of response to emergencies. Main switching equipment will be replaced in the 220 kV and 110 kV switchyards. It is planned to install 13 modern gas-insulated switches with better characteristics compared to air and oil devices. They have significantly lower failure rates and smaller maintenance and repair costs.

The capacity of the Nadym 220 kV substation is 250 MVA. It takes part in the power output from Urengoy and Novy Urengoy GRES to consumers of Salekhard urban district, Nadym and Priuralsky districts of the YaNAO, where more than 180 thousand people live and large centers of the enterprise are located for hydrocarbons production.
