Research on Error Ratio Calculator for the Electric Energy Meter Error Calibrator Device

摘要

With the rapid development of national economy, electric energy which is considered to be an important energy source has obtained wide application in all sectors of society. Electric energy meter is regarded as the main instrument in current measurement and economic settlement. Its accuracy has a direct relationship with the behalf between country and meter user. Therefore, it is important to calibrate the error of electric energy meter. At present, the error calibration method remain lag behind relatively, and the level of automation is low. This paper proposed an error ratio calculator which avoids the manual calculation of the traditional calibration pattern and improves the automatic and intelligent level of electric energy meter calibration.
