Abstract

In this paper, the authors propose a methodology to guide the verification of single-phase energy meters under sinusoidal and nonsinusoidal conditions. At first, a brief review is presented about definitions of the quantities that should be measured of monitored for revenue purposes and their relationship with electrical quantities that are recognized to be important in terms of metering accuracy. Then, a design of an experiment that allows the testing meters under a combination of disturbances showing positive and negative correlations are described. Finally, a hardware and software system to perform verification procedures in complex situations is presented with some preliminary analyses.
