Alternator

The alternator is a rotating machine consisting of a rotor and a stator allowing the mechanical energy from the turbine to be transformed into electrical energy.
The rotor is put into rotation by the mechanical power from the turbine, and turns at 1,500 rpm inside the stator, which is static. The electricity is produced in triphase at a frequency of 50 Hz in accordance with grid requirements.
The current is modified by a transformer to amplify its voltage from 20 kV to 400 kV, and to lower its intensity from 48,000 A to 2,000 A.
