Abstract
A wellness circuit is for a rotating electrical apparatus having a rated current and being operatively associated with an electrical switching, control, protection or monitoring apparatus structured to provide a number of currents and a number of voltages of the rotating electrical apparatus. The wellness circuit includes a current sensor scaled to the rated current and structured to provide a notch current signal representative of one of the number of currents; an interface to the electrical switching, control, protection or monitoring apparatus, the interface providing the number of currents and the number of voltages; and a processor employing the number of currents and the number of voltages from the interface and the notch current signal to determine wellness of the rotating electrical apparatus. The wellness circuit is structured to be separate from or added to the electrical switching, control, protection or monitoring apparatus.
