In all the electricity generation processes, i.e. combined cycle plants, cogeneration plants, conventional thermal power stations, nuclear power plants, hydropower plants, etc. both the motors as well as the electric generators play a key role.

Perhaps the most important role is played by the electric generator-turbine set, the heart of electricity plants, and which must always be operative. Nevertheless, the auxiliary processes are no less important for the smooth running of electricity generation processes.

In Combined Cycle plants, for example, we find medium-voltage motors and MWs of power, which drive the water circulation pumps of the high pressure steam turbines, the pumps of the open cooling circuit, the gas compressor, the diesel oil booster pump, etc.

Low-voltage motors and capacities of between 15 kW and 200 kW that drive the cooling fan of the gas turbine, lubrication pumps, hydraulic oil pumps, water circulation pump of the low-voltage turbines, condensate pumps, etc.
Lots of the abovementioned machinery is also found in most conventional thermal electricity generation or cogeneration plants.

These are all processes without which it would be impossible to generate energy. Many of them are driven by redundant machines in order to guarantee total availability.
The predictive maintenance of rotating electrical machinery guarantees the availability of all these assets and helps efficiently manage them as well as the other resources of electricity generation plants.

In this industry online predictive maintenance is key to:
Controlling the condition of the low and medium-voltage motors linked to the steam and gas turbines and to the cooling circuit.
