Abstract
An electronic electricity meter includes voltage sensors configured to generate measurements of voltage at voltage elements, current sensors configured to generate measurements of current through current elements, a microcomputer coupled to the current and voltage sensors and configured to control operation of the meter, and a memory coupled to the microcomputer including calibration constants to compensate for instrument transformer ratio and phase angle errors. The microcomputer is configured to use the calibration constants, when so instructed, to correct for measurement errors that occur based upon instrument transformer ratios and phase angles and to correct metering quantities calculated by the microcomputer.
