Abstract

A system and method to measure and control power usage within a residential or commercial building plurality having of electrical circuits electrically connected to an over-current protection device to ensure optimum energy usage therein. The system and method includes a power measurement and control device electrically connected to one of the electrical circuits by which a load draws power that is operable to (i) measure an electrical parameter of the electrical circuits, (ii) compare the measured electrical parameter to an ideal electrical parameter, and (iii) adjust power supplied to one or more of the electrical circuits based on the comparison of the measured electrical parameter and the ideal electrical parameter via a wall socket. The adjustment of power may be automatic or manual deactivation, decrease, and/or increase of power supplied to the electrical circuits via the wall socket so that such is equivalent to or less than the ideal electrical parameter.

5. The method according to claim 4, wherein the step of adjusting power includes notifying a user that the power factor or efficiency of the load has crossed the threshold resistance value and communicating at least one load replacement option to the user.

6. The method according to claim 1, further comprising the step of:

distinguishing the load from a plurality of other loads by determining each distance of the load and each of the plurality of other loads from the power measurement device.

7. The method according to claim 6, further comprising the step of:

obtaining an impedance profile centered at each distance of the load and each of the plurality of other loads.

8. The method according to claim 7, wherein the profile for the load is translated such that the profile is centered at a distance of zero from the power measurement device to simulate a measurement that is approximate to each load.
