On 21 October 2019, a new transformer was delivered to Yanikoski HPP of TGC-1. The replacement of equipment is carried out within the framework of the sweeping rebuild of hydro power plant.

The transformer produced by Starkstrom-Geratebau GMBH (SGB, Germany) replaces the old ASEA equipment (Sweden) and has improved technical characteristics for working in all modes and loads.

“The specialists will perform installation and adjustment works of all systems of the transformer. During its installation, a modern gas fire-extinguishing system will be applied for the first time at the HPP,” said Oleg Tyapinov, Chief Engineer of the Kolsky branch of TGC-1. “The complex improvement of the power equipment will increase the reliability of the hydroelectric power plant.”
