ABSTRACT:
An electric energy meter comprises a terminal unit and a measurement unit. The terminal unit includes plural electric lines each of which carries an electric current supplied from an external power source to a load, and a coil which is provided to at least one of the plural electric lines and converts the electric current flowing to the load into a magnetic field directly proportional to the electric current. The measurement unit includes a hall element which generates a voltage directly proportional to the magnetic field converted by the coil, a voltage detector which detects voltages of the plural electric lines, and a processing unit which calculates electric energy consumption based on the voltage generated by the hall element and the voltages detected by the voltage detector. The electric energy meter can facilitate the replacement.
