  • Method and apparatus for determining remaining life of conductor insulation systems through void size and density correlation
    Patent number: 6076411
    Abstract: A method of determining or assessing remaining life in insulation material includes using a computerized analytical model and supporting equipment to assess margin between an electrical insulation sample's given (i.e., known) void parameters (such as size and density) and void parameters corresponding to the threshold to integrity failure. The margin is then correlated to remaining life through use of known void growth rates, which are a function of temperature and other environmental service factors.

  • Method for detecting and measuring voids in conductor insulation systems
    Patent number: 6002790
    Abstract: A method of detecting and measuring voids in insulation material includes: providing a sample of insulation material; providing an imaging system for generating an image of the sample of the insulation material; analyzing the image to detect the presence of voids therein; and measuring the voids present in the sample to determine their size and density. Preferably, a nondestructive imaging system is utilized to detect and measure the voids.
