As part of another contract, EKRA Caucasus successfully completed the design and manufacturing of a 380V station service switchboard for a substation, ensuring reliable and uninterrupted power supply to protection relays, automation systems, and secondary circuits. The implemented solution is designed to operate with two independent power supply inputs, significantly enhancing the reliability of the substation’s power supply and reducing the risk of emergency outages. The system incorporates an Automatic Transfer Switch (ATS) function, which automatically transfers the load to the backup power source in the event of a failure of the main supply, without any intervention from operating personnel. During the design and implementation stages, special attention was paid to the performance and reliability of protection and automation systems, as their stable operation is a key prerequisite for the safe and efficient functioning of the substation. The applied technical solutions meet the requirements of modern power facilities and ensure a high level of operational reliability. EKRA Caucasus continues to implement advanced and efficient engineering projects, contributing to the development of energy infrastructure and enhancing the safety and reliability of power supply systems.
