The 110\/20 kV Coste\u0219ti transformer station in the Oltenia Energy Distribution portfolio will benefit from refurbishment works carried out by Adrem. The project is financed through the Modernization Fund, which aims to move from a classic configuration to a modern, digitized and secure architecture.<\/p>

The existing substation, equipped with 110 kV outdoor installations and 20 kV medium voltage cells, is undergoing an extensive modernization process covering both the primary and secondary switching parts, as well as the support infrastructure.<\/p>

In the 110 kV area, the works include the dismantling of the existing equipment and replacing them with modern switching and measurement equipment \u2013 circuit breakers, current and voltage transformers, separators and dischargers. At the same time, the foundations and support structures are restored, by switching from concrete solutions to metal structures, adapted to the new configuration of the station. A new surge protection installation and a grounding system sized according to current requirements are also being built.<\/p>

On the 20 kV side, the refurbishment involves replacing the existing cells with modern equipment, equipped with vacuum circuit breakers, as well as the complete modernization of the control, protection and measurement circuits. Internal service facilities are integrated and the feeding scheme optimised for more flexible and safe operation.<\/p>

A central element of the project is the implementation of a complete SCADA system, covering the entire chain \u2013 from field equipment to integration into the distribution operator’s systems. It allows real-time monitoring and operation of the station, while ensuring compliance with cybersecurity requirements.<\/p>

In parallel, the protection systems are being modernized by switching to numerical equipment, capable of providing advanced protection, command and signaling functions, contributing to the reduction of failure times and increasing operational safety.<\/p>

The project also includes a consistent component of construction works: the restoration and extension of the cable channels, the construction of retention tanks for transformers, the installation of the hydrocarbon separator, the modernization of the control building (including the SCADA spaces), as well as the implementation of auxiliary systems \u2013 lighting, ventilation, air conditioning and security.<\/p>

Through this investment, the 110\/20 kV Coste\u0219ti substation is brought to current operating standards, with an infrastructure ready for digitized operation, real-time control and integration into modern distribution networks.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
