【国家标准】 交流电测量设备　特殊要求　第2部分：静止式谐波有功电能表

This part of GB/T 17215.3 specifies classifications, technical requirements, accuracy indices and their test methods for static harmonic active energy meters (hereinafter referred as "meter").
It applies to static meters designed to measure and register electrical energy including fundamental wave active energy and positive / negative total harmonic active energy of 2nd to n th order harmonics on 50 Hz or 60 Hz networks with a voltage up to 600 V. It applies only to the type tests of newly manufactured meters.
This standard applies to meters in which their measuring element and display are enclosed in the same meter case for indoor and outdoor application. If the meter has other functional elements, like all components electrical energy registers, maximum demand indictors, registers for multi-tariff, etc. then the relevant standards for these elements also apply.
