Transmission revision
Refilling the turbine oil

In 2010 a 3-stage air filter was installed
Gas turbine generator
pull large revision with inductor
Insulation measurements
The conversion of the GT was carried out by Ansaldo Thomassen.

Steam turbine
open the turbine
Bring runners to the factory, material tests, blasting, sheet metal, balancing
Reseal parting joint
Close withdrawals that are no longer required
Realignment of the runner
Renewal of sealing steam control
New turbine control and adaptation to the steam turbine generator control system
The same work was carried out on the generator as on the GT generator.
The revision work was carried out by Turbomaschinen (TMS).
