Renovation of a power unit completed at Severnaya CHPP of TGC-1

The specialists of Severnaya CHPP completed the major repair of the power unit No. 5. The worn-off components and details were replaced and the technical diagnosis was carried out with approval for its further operation.

During the renovation, a complex of automated process control systems was installed on thermal and mechanical and electric equipment. Moreover, the oil circuit breakers of 6kV in the In-House Switchgear were replaced with vacuum ones.

"During the investment project implementation, we not only did a great job on the refurbishment of the power unit equipment but also significantly improved the workstation of our employees: the narrow-focused devices and self-recorders gave place to computer displays. These changes will positively influence the reliability of the overall facility's operation," explained Petr Chepelev, Director of Severnaya CHPP.
