Load measurement

Typically, loads are measured in all the main components of the wind turbine: blades, nacelle, and tower. Measurements are usually taken 25-50 times per second. The results are calculated as load relative to the wind speed, which is measured on the measurement mast in front of the wind turbine.

In high winds, it is possible to see the load on the blades with the naked eye, namely by the way the blade tips bend backward. The deflection of the blade tips on a large wind turbine in high winds is over 10 meters compared to calm conditions. The load measurements are intended to ensure that the finished wind turbine can withstand 25 years of operation and severe storms.
