Oscillation measurement of the drive train in wind turbines

Oscillation of the drive train (rotor imbalance, overloading) exceeding the limit values may lead to a failure of components and plant parts. Prerequisite for early recognition of damage and for predictive maintenance is the safe and accurate oscillation measurement of the rotor bearing, gearbox (rolling bearings, gear wheels) and generator. To measure these oscillations, high-precision and temperature-stable acceleration sensors from Micro-Epsilon are used.
