  • Testing procedure for evaluating diffusion and leakage currents in insulators
    Patent number: 7327132
    Abstract: A method for predicting long-term electrical insulation properties of composite materials in a moist environment. The method including the steps of providing a specimen, and testing the specimen to determine moisture content values and leakage current values at predetermined time intervals. The method further including the steps of determining a moisture-leakage current factor from the moisture content values and leakage current values, and using the moisture-leakage current factor to determine electrical insulation properties of the specimen.
    Type: Grant
    Filed: August 9, 2006
    Date of Patent: February 5, 2008
    Assignee: University of Denver
    Inventors: Daniel Armentrout, Lucas Kumosa, Maciej Kumosa
