This document contains captions for photos taken during a tour of a hydroelectric power station. The captions summarize key aspects of hydroelectric power generation, including the process of using falling water to generate electricity, safety equipment like helmets, transformers that change the voltage of electricity, water level monitors, flood gates for the dam, distribution machinery, and the lake created by the dam that provides the water power.

2. This is the process of hydroelectricity. This picture explains the
steps of the hydroelectricity process.

3. Here we can see one security measure in the station; the
helmet. The helmet is very important because protects the
head.

4. These electricity transformers are used to transform electricity
voltage, from high to low level.

5. These yellow and black lines are used to mesaure the level of
water that it is in the dam.

6. These are all the doors that Colbun has to empty the dam that it is
flooded.

7. This is the upper part of one of the doors that Colbun has to
empty the dam that it is flooded.

8. In this picture we can see the «Río Maule», and the part
where the water of the dam goes if it is flooded.

9. This is the logo of Colbun. It is important because it represents
Colbun Hydroelectricity Station without confusing other stations

10. This is an important machine because distributes the electricity
for the houses, the industries, etc

11. This is the lake of Colbun. This lake (dam) was created because of
the water falling, that is essential in the process of
hydroelectricity.
