Abstract
A method for continuously determining the consumed insulation life of an electrical winding in a rotating machine is described incorporating the steps of selecting constants based on the class of insulation material and rotating machine power rating, measuring the temperature of the insulation over time, determining the consumed life of the insulation for consecutive periods of time and summing the consumed life. The invention overcomes the problem of determining consumed life of electrical insulation.
