Introduction: The Hidden World of Turbine Faults
Wind turbines are the most critical equipment in the renewable energy sector. However, maintaining these massive structures is a challenging and costly task. Faults in turbine blades often start invisible and go unnoticed until they turn into serious damage.
At Windlar, we detect turbine faults at early stages with our drone technology and AI-powered analysis systems. This way, we prevent major repairs, saving both time and money.
Common Faults in Turbine Blades
1. Surface Erosion and Cracks
Cracks forming on the blade surface gradually grow, causing structural weakening. Especially:
– Thermal stress from weather conditions
– UV rays and salt water effect (offshore)
– Particle erosion
These factors reduce the strength of composite materials.
2. Delamination
Separation of inner blade layers threatens structural integrity. Can be detected early with thermal imaging.
3. Lightning Damage
Turbine blades can be lightning targets. Damage from strikes causes performance loss.
4. Blade Tip Erosion
Wear on the leading edge due to high-speed rotation of water and particles can reduce energy production by 5-20%.
