In this paper, the efficiency of a 2.75 MW nacelle drivetrain on a test bench was determined traceably at various load points. For this purpose, so-called transfer standards for mechanical and electrical power measurement were additionally installed

For torque transducers above 1.1 MNm, no traceable measurement has been possible to date. Therefore, an extrapolation method deploying measurement data from partial ranges is to be developed. Both partial and full range measurements up to 20 kN m are
