"Alta kraftstasjon" (4 of 5)
Description
This simple illustration shows the main principles in the hydroelectric power plant:
Firstly, water is collected in the dam. Thereafter it is released through tunnels and shafts down to the power station and turbines. The turbines are located at the lowest part of the complex. Water impels the turbine wheel around which creates mechanical energy. The generator is mounted on the same axle shaft as the turbine wheel. This generator converts the mechanical energy from the turbines into electrical energy. The transformer converts the electrical energy to be emitted through a power line. The water is released at a lower level than the turbines.
This illustration is from a book released by the Norwegian Water Resources and Energy Directorate titled Kulturminner i norsk kraftproduksjon, Oslo 2006, p. 35.
