Current-voltage characteristic of the wind wheel

Principle

This experiment can also be carried keeping the distance constant but changing the number of rotor vanes. In the following example, the performance dependence on the voltage is examined using all 6 rotor vanes but different distances (5 cm and 10 cm).

Benefits

• Experiment is part of a complete solution set with a total of 26 experiments for Renewable Energy solar cells, wind power, water power
• Safe experimentation: The fan in the blower is protected against touch
• The power supply used is versatile and is particularly suitable for pupil tests for all ages

Tasks

How high is the performance of a wind generator?

The current-voltage characteristic of a wind generator is recorded under differing conditions in this experiment and the performances are then calculated from the results and compared.
