The efficiency of a wind turbine generators (WTG) influences the energy yield and thus the operator’s profit. Negative influencing factors, such as dirt or rotor blade erosion, as well as damage to aerodynamic aids such as boundary layer fences, vortex generators and zig-zag band turbulators can significantly reduce the yield. Thermography offers excellent opportunities to detect this kind of defects from several hundred metres away on the rotor blades of running wind turbines, in order to then be able to take effective steps to remedy such problems.
InfraTec does not have the power to change the wind, but during their webinar on demand, their expert speakers will explain how thermography can help you get the most out of your wind turbines. In addition, there is a technical lecture from thermography practice.

Thermography for Optimisation of Installed Wind Turbines
Due to the decreasing number of suitable locations for wind turbines and the increasing push towards renewable energy sources, new activities have been introduced to improve the efficiency of rotor blades for wind turbines.

High-end Infrared Camera in Use
Damage to the rotor blades of wind turbines is often not visible to visual cameras. By using thermography, conspicuous features on the inner blade structure, delaminations, bubbles in the bonding, bonding defects, ondulations, dry spots, water or ice in the blade and vortex structures can be detected.
