Abstract

A system for predicting a condition includes an electric machine having slip rings and an exciter providing current and voltage to the electric machine through the slip rings. The system also includes a monitoring device that measures the current and voltage provided by the exciter to the electric machine and that forms a regression model from a current sample and compares values from a next sample to values predicted by the regression model.
