The present application relates to a method for determining an efficiency and/or for calibrating a torque of a drivetrain (1), in particular a drivetrain (1) of a wind turbine. The method for determining an efficiency and/or for calibrating a torque of a drivetrain (1), in particular of a drivetrain of a wind turbine, is particularly suited for carrying out on a test rig and comprises two tests. The drivetrain has a motor-side end at a main shaft connectable to a motor and a generator-side end, between which ends a generator is arranged. In a first test, the motor-side end of the drivetrain (1) is driven. A variable dependent on the main shaft torque is thereby determined at the motor-side end of the drivetrain (1) and an electrical power P.sub.elec is determined at the generator-side end of the drivetrain (1). In a second test, the generator-side end of the drivetrain (1) is driven and the variable dependent on the main shaft torque is likewise determined at the motor-side end and the electrical power P.sub.elec is determined at the generator-side end. An efficiency and/or calibration parameters is/are determined from the electrical power values and the variables dependent on the main shaft torque determined in the first test and in the second test.
