Boroscopy & Thermography on Wind Turbines
Early detection of component damage by boroscopy & thermography
Since 2004 the 8.2 GROUP has performed more than 3,000 inspections by boroscopy.
During this inspection a visual examination is made with the help of a video camera.
There is no other technique which provides a quick, secure and reliable optical examination of difficult to access areas such as cavities or internal components of a machine.
Apart from being able to visualize the internal structure of objects the boroscopy offers the possibility to assess the condition of objects and possible defects. Costly standstill periods for wind turbines will be reduced if defects of components are detected at an early stage.
Inside of wind turbines, the boroscopy is mainly used for the inspection of gear boxes.
However, 8.2 experts also use boroscopy for the inspection and assessment of
- generators,
- pressure chambers of rotor blades,
- other components.
Electrical components an also be checked using Thermography:
In this way many errors can be identified and corrected in a timely manner such as:
- Hotspots on defective PV modules
- improper cable connectors
- increased contact resistance at cable connections
Thus, problems caused by cable connections installed in an inappropriate way can be detected more easily.
