Simulation analysis of power-frequency electromagnetic field interference on smart meters

摘要

In this paper, based on the principle of electromagnetic interference on some key parts of smart meter, using power-frequency electromagnetic field as interference source, power transformer, the voltage transformer and the current transformer of a smart meter in the interference of the power-frequency magnetic field are analyzed and studied with the finite element software ANSYS electromagnetic analysis function. Based on the theory of finite element analysis, finite element analysis model is established, and then calculated, compared, and analyzed. According to the result of finite element calculation and analysis, some measures for preventing electromagnetic interference of smart meters are also proposed.
