Abstract: A poly-phase electric energy meter comprises a front-end that converts analog current input signals and analog voltage input signals to digital current and voltage samples and a micro-controller for computing power consumed. The front end includes first and second input channels. Each input channel has a multiplexer, an analog-digital converter, a de-multiplexer and a set of data registers. The first input channel receives current input and the second input channel receives voltage inputs. A multiplexer control causes the first and second channels to sequentially sample the current and voltage for one phase at a time and store digital data in corresponding data registers. The micro-controller computes energy consumed from the simultaneous current and voltage samples.
