Abstract
Described herein are methods and systems for identifying individual branch circuits coupled to a power distribution point. A sensor module positioned in proximity to the power distribution point and having a plurality of magnetic field sensors senses a magnetic field emitted by each of a plurality of branch circuits coupled to the power distribution point. A processor coupled to the sensor module determines a response of each magnetic field sensor to each of a plurality of changes in power associated with at least one of the plurality of branch circuits. The processor positions the responses of the magnetic field sensors to each change in power on a point in a multidimensional space, where each dimension of the multidimensional space corresponds to a magnetic field sensor. The processor identifies clusters of the points in the multidimensional space, each cluster representing a different branch circuit and having a different vector direction.
