Beschreibung
Zusammenfassung:	Described embodiments generally relate to a method of determining power delivered by a cable, the method comprising receiving data related to a residual magnetic field produced by the cable; determining a proportionality factor relating the received data to the power delivered by comparing the residual magnetic field data to independently measured reference data related to the power delivered by the cable; and based on the proportionality factor, determining the power delivered by the cable; wherein the cable comprises at least two conductors, and wherein the physical arrangement of the at least two conductors is unknown; and wherein the independently measured reference data is aggregate data, being the sum of data related to power consumption through the cable and power consumption unrelated to power consumption through the cable.
