What’s inside a wind turbine?

This video posted on Youtube.com has sparked my attention. Firstly, because there are not so many videos like this that explains the main parts of a wind turbine, and second because it is worthy and is well-structured. The video is made by UVSAR, a British company which provides technical services for all those involve in work at height.

The video shows us the layout of two typical wind turbine generators, from the transformer at the floor level, ladders (or elevators), to the electrical cables attached to the walls of the tower.

However, the most important is the electrical and mechanical equipment on the top. In the big ones (for example, 2 MW wind turbines) also the nacelle can contain the transformer with the indispensable electrical and mechanical components such as, the generator, the gear-box, so on. Video very interesting to understand the basic functions.
