<p>A test rig that is suitable for testing a gearbox (118) and an electromechanical energy converter (119), for example a nacelle of a wind power plant, is presented. The test rig comprises a gear system (101) and a power transmission shaft (104, 113) which constitute together with a gearbox under test a mechanical closed power loop which makes possible to impose high test torque to the gearbox under test so that the maximum testing power of the gearbox is significantly higher than the maximum power of drive motors (108-111) of the test rig. Furthermore, the test rig comprises a rotatable connection interface (112) suitable for being connected to an input shaft of the electromechanical energy converter under test so that practically all the mechanical power of the drive motors can be directed to the electromechanical energy converter under test.</p> |
