A method and apparatus are provided for measuring a quality of insulation surrounding rotor bars of a rotor of a squirrel cage motor. The method includes the steps of applying an alternating magnetic flux to opposing ends of the rotor measuring a power level absorbed by the rotor as a result of the applied alternating magnetic flux. The method further includes the step of using the measured power level as a relative measure of the quality of the insulation of the rotor bars.
La présente invention concerne un procédé et un appareil servant à mesurer la qualité de l'isolation entourant les barres de rotor d'un rotor de moteur à cage d'écureuil. Le procédé comprend l'application d'un flux magnétique alternatif aux extrémités opposées du rotor, la mesure de la quantité de puissance absorbée par le rotor suite à l'application du flux magnétique alternatif. Le procédé comprend également l'utilisation d'une quantité de puissance mesurée en tant que mesure relative de la qualité de l'isolation des barres de rotor.
