ABSTRACT:
A method is described for metering electrical energy. The method includes sensing each phase of a circuit to generate analog voltage signals and analog current signals associated with each phase. The analog voltage signals and said analog current signals are converted into digital voltage signals and digital current signals, respectively, using time division multiplexing to provide three digital outputs. The digital outputs comprise at least one digital voltage signal and at least one digital current signal associated with the same phase. The digital outputs are processed to generate signals representative of real power, the magnitude of reactive power, and apparent power, wherein the signals representative of the magnitude of reactive power are generated from the signals representative of real power and the signals representative of apparent power.
