Claim 0:
1. A device for determining a current or power consumption at a primary wire, the device comprising:
a current transformer, having a turns ratio and provided with a secondary wire, the current transformer adapted to be installed upon the primary wire in order to step-down a primary current at the primary wire to a secondary current at the secondary wire according to the turns ratio; and
a non-volatile memory connected to the current transformer, wherein the non-volatile memory is configured to store calibration data across a range of load currents wherein bytes of a calibration block are mapped to specific calibration values,
wherein the current transformer is connectable to a downstream meter for measuring a measured secondary current or a measured power consumption at the secondary wire, and wherein the current transformer is configured to communicate the calibration data to the meter, in order to calibrate the measured secondary current so as to determine the primary current or to calibrate the measured power consumption so as to determine the power consumption.
