METHODS, SYSTEMS AND DEVICES FOR MONITORING POWER CONSUMPTION AND GENERATION

Embodiments generally relate to a method for allowing power supplied through a cable to be determined. The method comprises receiving magnetic field data, the magnetic field data relating to a magnetic field generated by the cable, receiving reference data, the reference data relating to a current supplied to one or more monitored loads powered through the cable; based on the received magnetic field data and reference data, determining at least one parameter of a function that relates the magnetic field generated by the cable to the power supplied through a cable; and making available the at least one parameter, so that a power supplied by the cable can be determined based on the at least one parameter and a magnetic field value. The one or more monitored loads are a subset of all the loads powered through the cable.
