Abstract
Since the end of year 2009, State Grid Corporation launched the project of using smart energy meter, whereas the single-phase smart energy meter has the functionality of real-time current measurement on Phase&Neutral cable;The theoretical value of current on Phase&Neutral cable should be basically equal, however due to the changing load from end users, and Phase&Neutral current data acquisition are not well synchronized, for the moment the current data on Phase&Neutral cable collected by Metering Data Acquisition system has great difference, which is incapable of re-flecting the onsite operating conditions, and also not good enough for analysis of metering issues, such as measurement error, current bypass, etc., This essay presents an optimized 1-Minute average current measurement & data collection method, which ensures more accurate current data on Phase&Neutral cable to be collected by Metering Data Acquisi-tion, true reflection of field operating conditions, and provide reliable data and information for analysis of metering is-sues such as measurement error, current bypass, etc.关键词
