USING STEADY-STATE CHANGES TO DISCERN THE OPERATING PERFORMANCE OF AN INDIVIDUAL MACHINE OPERATING ON A COMMONLY SUPPLIED ELECTRICAL NETWORK CONNECTED TO MULTIPLE MACHINES

摘要

A device, which may be embedded in a power distribution enclosure, enables analysis of the conditions of an electromechanical machine operating on a commonly supplied network with other electromechanical machines. The analysis preferably uses aggregate operating voltage and current signals supplied to or from such machines along with known changes in steady-state conditions of one or more machines to discern the discrete effect of one or more machines to the aggregate electrical signal. Such discrete effect can then be associated with the operating performance of the individual machine. And, since such voltage and current signals are normally readily available at the enclosure, wiring or any other communication means to any sensors on the electromechanical machines or devices are not necessary. The embedded device may optionally receive or transmit information to a computing or monitoring device remote from the enclosure.
