Research of smart meter design scheme based on IR46

Abstract

This paper compares the differences between the International Recommendation46 (IR46 for short) and the current national standards for electric energy meter of the accuracy classes, testing requirements, software protection and so on. The national meter adaptability of IR46 is analyzed, and a technical proposal of dual-core smart meter is advanced. This proposal could match the testing and software protection requirements for IR46, and could implementation in China.
