Optical 3D coordinate measurement technology from GOM is the ideal solution for capturing the complex geometries and free-form surfaces of Pelton wheel, Francis and Kaplan turbines.

It is used to analyze blade geometry tolerances as well as the distances and angles between individual blades to ensure that turbines rotate smoothly and with minimum vibration. In addition, reverse engineering and a golden master are ways of greatly improving turbine efficiency. Reliable and robust measurement technology from GOM provides analysis results fast, especially when problems occur with installed turbines.
