Patent ID: 7962298

Claim:
A revenue class power meter comprising; a plurality of sensors configured to be coupled with a plurality of corresponding power conductors, wherein each of the sensors are operative to sense a power parameter of electrical energy present in the corresponding power conductors and generate respective input signals representative of a respective sensed power parameter; a plurality of transducers coupled with the respective sensors, the transducers operative to generate a voltage representation of the respective sensed power parameter; a plurality of filters coupled with the respective transducers, the filters operative to attenuate high frequency signal components about 1 kHz greater than the highest frequency desired to be measured , wherein each of the filters are configured to provide a predetermined signal propagation delay, signal gain and corner frequency that are substantially the same for all of the filters; a revenue class metering module configured to receive the input signals, wherein the revenue class metering module is operative to generate revenue accurate power consumption information based on the received input signals; and a power quality metering module coupled with the filters and configured to receive the filtered input signals, wherein the power quality metering module is operative to generate power quality information based on the received filtered input signals.
