Abstract

Accuracy is perhaps the most important attribute of high-end metering. The overall accuracy of a metering installation is dependent on a combination of the accuracy of the meter and the instrumentation transformers. Optimization of the analog-to-digital converter (ADC) resolution and the time averaging period in the root mean square (rms) calculation can improve meter accuracy. This paper shows that appropriately changing either of these characteristics can increase the overall metering accuracy
