The Nadăş 110/20/10 kV transformer station was put into operation in 1978 and supplies the 10 and 20 kV electrical distribution network in the city of Cluj-Napoca, the main beneficiaries being domestic, commercial and industrial consumers.
The project consisted of DDE and AS BUILT design, replacement of medium voltage cells with new cells - 26 MOD 24 cells, modernization of 3 110 kV cells (2 transformers and 1 coupler), replacement of protection cabinets and internal services with cabinets EnergoBit branded products.
Modernization works include:
• primary replacement equipment – 110kV (separators, switching devices, power transformers, voltage transformers, arresters);
• equipping a 110kV transformer cell on free space and mounting a 110/20kV transformer;
• replacement of the 110kV bar;
• modernization of transformer cell protections;
• modernization of the general signaling system;
• creating two resistance treatment groups - one of 10kV, another of 20kV;
• integration of the designed equipment into the existing SCADA control system;
• replacement of medium voltage cells in the connection station, both at 10kV and at 20kV;
• modernization of automation installations at the station level (AAR mt, DRRI, DAS-f);
• modernization of own DC and AC services;
• completion of the lightning installation;
• modernization of the interior and exterior lighting installation;
• construction works (foundations, cable ducts, station building);
At the moment, our colleagues are working on equipping the 110KV transformer cell and building the 2 neutral groups.
The works are complex, but our colleagues are ready to respond with enthusiasm and professionalism to successfully complete the project.
