Abstract:
An arrangement for measuring electrical energy consumption includes an input circuit operable to generate a first signal representative of a line voltage waveform and a second signal representative of a line current waveform. The arrangement further includes a processing circuit operable to generate energy consumption data based on the first signal and the second signal. The processing circuit is further operable to generate a first pulse waveform having a plurality of output pulses based on the energy consumption data, each output pulse corresponding to a quantity of energy consumed. The arrangement further includes a wireless transmitter coupled to the processing circuit, the wireless transmitter configured to transmit an RF signal each time the first pulse waveform changes state. The arrangement also includes an external device positioned remote from the electrical utility meter, the external device including a receiver configured to receive the RF signal.
