As wind turbine technology evolves, the reliability and performance of turbine components become increasingly vital. Non-Destructive Testing (NDT) plays a crucial role in ensuring the safety, reliability, and longevity of these components. Wind turbines operate under harsh environmental conditions and are subjected to mechanical stresses that can lead to potential wear, cracks, or structural defects. NDT methods, such as Eddy Current Testing (ECT) and ultrasonic testing, are used to detect flaws in critical parts like the blades, gears, towers, and bearings early on. By identifying these issues before they develop into serious problems, NDT helps reduce maintenance costs, prevent unexpected failures, and enhance the overall efficiency and lifespan of wind turbines, ensuring continuous, reliable energy production. 

A wind turbine relies on various structural components to convert wind energy into electricity, with the tower and bearings being some of the most important. The tower provides the essential structural support, while the bearings enable smooth rotation of key components under heavy loads. Together, these elements are crucial for maximizing the efficiency of wind energy conversion.
