| Abstract: | Compared with metering system in traditional substation, the paper analyzes the principle and structure of electronic transformer and smart energy meter. The output of electronic transformer is digital frame basic on IEC61850-9-1, and the smart energy meter calculates the power directly according to the digital signal frame. The working principles and interface methods have changed essentially. Therefore, the paper analyzes and researches the calibration principle and mode of electronic transformer and smart energy meter. It has good guidance for the research of metering system and the development of calibration technology. |
