Abstract:
1. A method comprising: identifying a data set generated based on sampling at legs of an alternating current service, the legs providing a common power supply a plurality of electrical devices; with a processor and a memory, identifying, based on said data set, a first instance data structure corresponding to a first on-off cycle of a first electrical device of the plurality of electrical devices, the first instance data structure including: based on the identifying the first instance data structure, subtracting from the data set a contribution by the first on-off cycle, wherein the subtracting the contribution results in a residual data set; and determining whether the residual data set includes a contribution by any on-off cycle of another electrical device of the plurality of electrical devices, wherein the first on-off cycle and the any on-off cycle each start with a respective step change event of a corresponding electrical device and ends with a respective step change event of the corresponding electrical device.
