This article compares the differences between the International Recommendation46 (IR46 for short) and the current national standards about electric energy meter, which from the accuracy classes, testing methods software protection requirements and so on. The national meter adaptability of IR46 is analyzed, and a technical proposal of smart meter with ‘double-chips’ is advanced which could match the testing and software protection requirements for IR46, and it provides a reasonable solution idea for the future IR46 implementation in our country.
