Accelerometers on the inner and outer rings of each pitch bearing, the blade and the pitch gearbox identify vibration transmission characteristics.
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.
