1. A method for monitoring the health-state for electronic equipment, comprising:

  • measuring current and voltage at an input and an output of the electronic equipment and acquiring data therefrom;

    using the measured data, calculating performance metrics for the equipment;

    separating the measured data into a plurality of data classes;

    generating performance models for at least one data class;

    extracting diagnostic features from measured data values by comparing calculated performance metrics with the diagnostic models; and

    identifying the source and severity of a fault based upon the diagnostic features.
