Turbogenerator of TVV-350-2U3 type for Kostromskaya GRES, unit No. 3.

The generator is a three-phase synchronous electrical machine with an implicit pole rotor. It consists of a stationary part - the stator, which includes the core and winding, and a rotating part - the rotor, on which is placed the excitation winding, powered by direct current. Structural design of the generator is closed hermetic. In order to divert the losses generated in the stator and rotor windings, the magnetic conductors (in the stator core and in the rotor shaft) are provided for direct cooling of the rotor winding with hydrogen, the stator winding with distilled water and filling of the stator housing with hydrogen
