  • Method and apparatus for generator stator bar wedge pressure testing
    Patent number: 6631335
    Abstract: Systems and methods are provided for measuring pressure on a member. The systems and methods include exciting the member to create a vibratory response in the member and detecting the vibratory response. The vibratory response is then compared to at least one of a plurality of previously recorded vibratory responses of the member. The pressure on the member is then estimated based on the comparison of the vibratory response to the plurality of previously recorded vibratory responses.

  • Method and apparatus for generator stator bar wedge pressure testing
    Publication number: 20020198669
    Abstract: Systems and methods are provided for measuring pressure on a member. The systems and methods include exciting the member to create a current vibratory response in the member and detecting the current vibratory response. The current vibratory response is then compared to at least one of a plurality of previously recorded vibratory responses of the member. The pressure on the member is then estimated based on the comparison of the current vibratory response to the plurality of previously recorded vibratory responses.
