Abstract:
A power consumption meter for measuring the power consumed by a load on a power conductor, the meter comprising:first GMR sensor means, the first GMR sensor means being disposed proximate the power conductor and being magnetically coupled to the power conductor, the first GMR sensor means for detecting magnetic flux in the power conductor and producing a first output responsive to the detected magnetic flux that is representative of the current flowing through the power conductor;second GMR sensor means, the second GMR sensor being disposed proximate the power conductor and being magnetically coupled to the power conductor, the second GMR sensor for detecting magnetic flux in the power conductor and producing a second output responsive to the detected magnetic flux that is representative of the voltage on the power conductor; andprocessor means being operably communicatively coupled to the first and second GMR sensor means and being responsive to the first output and the second output for producing a third output that is representative of the energy consumption of the load on the power conductor.
