ABSTRACT:
An example embodiment of an electrical-energy meter comprises a transformer for producing an electrical output proportional to an electrical current in a conductor of electrical energy, a circuit board electrically coupled to the transformer for facilitating the calculation and displaying of a cumulative amount of electrical energy passing through the conductor of electrical energy, a first optical transmitter, a second optical transmitter, and an optical receiver. The first and second optical transmitters and the optical receiver are coupled to the circuit board. The first optical transmitter and the receiver facilitate optical communications between the electrical-energy meter and a first type of external device. The second optical transmitter and the receiver facilitate optical communications between the electrical-energy meter and a second type of external device.
