A maker of custom wind turbine blades and ventilation equipment requested Sound Answers to identify an imbalance related issue at the request of their customer. Operating vibration measurements were conducted on the wind turbine located in Mexico. FFT, order analysis, and balancing techniques were utilized to characterize the imbalance associated with the blades of the system. Additionally, efforts were provided on the wind turbine to troubleshoot a vibration alarm system fault. Measurements for this showed a resonance issue not related to imbalance, which was the significant contributor to the vibration faults the customer was experiencing.
