The performance index of electromagnetic compatibility of electronic energy meter has become an important technology content when researching and developing. Electromagnetic interference is a significant impact to the safe and stable operation of the energy meter. This paper introduced the common types of electromagnetic interference, focused on the suppression mechanism of filter. For MDP2002A standard three-phase wide-range power meter, through experimental comparison, analyzed the filter impact for voltage and current of meter. This paper can provide reference for the study of electromagnetic compatibility of meter.
