Claim 18:
19. An electricity usage metering (EUM) system comprising:
a coupling system to couple the EUM system to a monitored source;
a current transformer (CT) in which a fluctuating secondary magnetic field is induced from a fluctuating monitored magnetic field in the monitored source and from which the reading of the fluctuating monitored magnetic field is obtained based on the fluctuating secondary magnetic field, the CT comprising an advanced nano-layered material that operates at low temperatures disproportionate to saturation levels, and the CT having a top-end limit beyond which physical limitations of the CT cause the reading to comprise an error outside an acceptable ratio error; and
a processing circuit to obtain the reading of the fluctuating monitored magnetic field in the monitored source and, if the reading is beyond the top-end limit of the CT, to employ a transformation to correct the reading to be within the acceptable ratio error.
