Electric Energy Meter

The verification of electronic type electric energy meter is under strict reference conditions, but some special operating conditions at locale will exceed the standard scopes. In order to improve the calculation accuracy and operating reliability of electric energy meter under operating conditions, it is necessary to study the operating conditions. According to the working principle and the standard verification regulation of electronic type electric energy meter, this paper summarizes these operating conditions: low power factor, harmonic waves, dynamic impulsive load, voltage fluctuation and outside magnetic field of power frequency, then analyzes the causes of operating conditions and their influence on electronic type electric energy meter, eventually lays foundation for thorough and systematic study of electric energy meter in the operating conditions, and establishes measurement center database of operating conditions.

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.
