Claim Text:
1. A power monitoring system comprising: (a) a plurality of current sensors suitable to sense respective changing electrical current within a respective conductor to at least one load; (b) at least one conductor sensing a respective voltage potential provided to said at least one load; (c) a power monitor that determines a power of said at least one load based upon a signal from at least one of said current sensors and a signal from at least one said conductor; (d) said power monitor receiving at a single input to a microprocessor a signal including data simultaneously representative of at least one of (i) a signal from a first one of said current sensors and a second one of said current sensors, and (ii) a signal from a first one of said at least one conductor and a signal from a second one of said at least one conductor; (e) said power monitor determining at least one of (i) a frequency of at least one of said signals from said current sensors, (ii) a frequency of at least one of said signals from said conductors, (iii) a phase relationship between at least two of said signals from said current sensors, (ii) a phase relationship between at least two signals from said conductors.
