  • Device for monitoring corona discharge in a dynamoelectric machine with detection probe movable in longitudinal and circumferential direction
    Patent number: 5252927
    Abstract: In the device for detecting partial discharges in winding elements of an electrical machine, the winding element to be investigated is sampled over its length, with high voltage applied, by means of a drivable probe and the radio frequency signals initiated by the partial discharges are received by means of an antenna. The antenna signal is detected and evaluated in a test set (11) connected downstream. The probe is arranged on a support which can be conveyed, under remote control, in the machine longitudinal direction, by means of tension cables (4, 5) or an axle rod, or is provided with a dedicated drive.
