ABSTRACT:
A power meter is disclosed for determining power parameters for power lines having periodic 3-phase voltage and current signals distributed to a plurality of power equipment. The 3-phase voltage and current signals have a fundamental frequency. The power lines are connected to at least one transducer which generates analog signals representing the voltage and current signals. The power meter includes receiving circuitry which can be connected to the at least one transducer to receive the analog signals. An analog to digital converter receives the output signal from the receiving circuitry and converts the voltage and current signals to digital data representing the analog signals. A processor receives the digital data and includes logic for calculating the power parameters. The power meter compensates for errors caused by not sampling synchronous to the fundamental frequency of the signals.
