Study on electrical energy meter for energy measuring under harmonics condition

摘要

In this study, the principle and influence of electrical energy meter measurement were analyzed under harmonics condition. Subsequently, a test platform was set up to investigate the impacts of three typical harmonic waveform on the performance of electrical energy meter. The electric energy measurement results were obtained under sine wave and harmonics conditions. The test results were in accordance with theoretical analyses. It is very useful for the quality of electrical energy meter testing and assessment.
