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.
