  • Method and device for indicating an electric discharge inside a bearing of an electric drive system
    Patent number: 9140758
    Abstract: The present invention relates to a method for indicating an electric discharge in a non-conducting medium (22) between a rolling element (20) and a raceway (16, 18) in a bearing (12) of an electric drive system (10). The method comprises: remotely detecting radio frequency signals emitted from the electric drive system, which signals comprise a radio frequency signal associated with an electrical discharge in the non-conducting medium, processing the detected radio frequency signals to estimate the electric discharge, and indicating the estimated electric discharge. The present invention also relates to a corresponding device (30, 50, 70, 90) for indicating an electric discharge in a non-conducting medium between a rolling element and a raceway in a bearing of an electric drive system.
