Claim Text:
1. A method of monitoring power consumption of an electrical device, the method comprising: automatically deriving a power load signature for an electrical device, the power load signature being unique to the electrical device concerned, and being derived from power consumption measurements for the electrical device concerned using pattern matching of power consumption measurements across three electrical supply phases; automatically identifying an electrical device using such a power load signature using pattern matching of power consumption measurements across three electrical supply phases; and monitoring power consumption of such an identified electrical device, wherein the power consumption measurements include at least one of a characteristic chosen from on/off transients, signal shape/pattern including signal shape/pattern over time, frequency components, changes in phase angle, load change in RMS, relative and reactive power change, three phase pattern and any combination thereof.
