  • Insulation defect detection of high voltage generator stator core
    Patent number: 9658192
    Abstract: In a general methodology for insulation defect identification in a generator core, a Chattock coil is used to measure magnetic potential difference between teeth. Physical knowledge and empirical knowledge is combined in a model to predict insulation damage location and severity. Measurements are taken at multiple excitation frequencies to solve for multiple characteristics of the defect.
    Type: Grant
    Filed: January 16, 2013
    Date of Patent: May 23, 2017
    Assignees: Siemens Corporation, Siemens Energy, Inc.
    Inventors: Xuefei Guan, Jingdan Zhang, Shaohua Kevin Zhou, Mark W. Fischer, Waheed A. Abbasi, Scott A. Karstetter, Christopher John William Adams
