Abstract:
A power consumption monitor, system, and method for monitoring power consumed by equipment, appliances, devices, buildings, and campuses is accomplished by passive sensors () that detect power transmitted by individual conductors (C), and which include a current to voltage transformer with a passive, open-circuit electromagnetic force concentrator () positioned near the conductor (C). The sensor () generates an amplitude signal proportional to the power passing through the conductor (C). Programmable radios on a chip () and systems on a chip () are used to transmit the amplitude signal to a monitor () that displays the power being consumed along with actual and estimated cost and historical information. Software programs are implemented across the sensors () and monitors () and a remote computer () to enable real-time monitoring power consumption with a resolution that spans from entire campuses down to single devices.
