Borescopy in wind turbine generators is a non-invasive inspection technique. It involves using a specialized Borescope, which is a long, flexible tube with a camera at one end, to visually inspect the internal components of the gearbox and main bearings.

The Borescope is inserted into an access point in the wind turbine housing, allowing it to reach the gearbox and main bearings.
The camera at the end of the Borescope captures high-resolution images and videos of the interior components. These visuals are transmitted in real-time to an external monitor where technicians can analyze the condition of the components
During the inspection, technicians look for signs of damage, wear, corrosion, or misalignment.
Common issues include pitting, chipping, overheating, and lubrication problems in the gearbox. In the main bearings, issues may include uneven wear or scoring.
Borescopy is non-destructive and minimizes downtime because it doesn’t require disassembling the wind turbine.
It provides an accurate assessment of the gearbox and main bearings’ condition, allowing for timely repairs or replacements.
Early detection of issues extends the life of these critical components and reduces maintenance costs.
If issues are identified during the Borescopy, maintenance or repairs can be scheduled based on the severity of the problem.
This proactive approach ensures that the wind turbine operates optimally and avoids catastrophic failures.
Safety is a paramount concern in the wind energy industry. Regular Borescopic inspections contribute to safe operations by identifying potential hazards.
Furthermore, Borescopy helps maintain high-quality energy production, as well-maintained components are less likely to fail.
In summary, Borescopy plays a vital role in the maintenance and longevity of wind turbine generators by allowing thorough inspections of critical components like the gearbox and main bearings. This non-invasive technique is instrumental in early issue detection, cost-effective maintenance, and ensuring the continued production of clean and renewable energy.
