Original language description
This report has been produced within the EMPIR project entitled Traceable Mechanical and Electrical Power Measurement for Efficiency Determination of Wind Turbines or 19ENG08 WindEFCY. More information about this collaborative research project can be found on the project’s website https://www.ptb.de/empir2020/windefcy/home/. This report describes the calibration of the 5 MN m torque transfer standard partially up to 1.1 MN m including an extrapolation of the calibration results up to 5 MN m as well as the use of the transducer under rotation up to 22.5 rpm. Moreover, a 125 kN m torque transducer was calibrated statically for usage under rotation up to 1600 rpm. Other influences on statically calibrated transducers when used in test benches, such as different data acquisition and filter settings, rotational speed and non-step application of loads, were investigated.
