Accelerometers on the inner and outer rings of each pitch bearing, the blade and the pitch gearbox identify vibration transmission characteristics. The hub-installed monitoring system collects impact vibration data to detect wear, corrosion, pitting, spalling, gear tooth breakage and pitch imbalance.
