GB/T 17215的本部分规定了静止式谐波有功电能表(以下简称仪表)的分类、技术要求、准确度等级及其试验方法。
本部分仅适用于在50 Hz或60 Hz供电网络中测量并记录基波有功电能、规定的(第)2~(第)n次谐波的正向有功电能之和与反向有功电能之和的新制造的仪表,并且仅适用于其型式试验。
本部分仅适用于安装在户内或户外使用的,由测量元件和显示器装在同一表壳内的仪表。如果仪表具有其他功能单元,如:全波电能、最大需量、多费率等包封在同一表壳内,则相应的标准适用于这些功能单元。
本部分不适用于:
a) 接线跨接端电压超过600 V(多相仪表为线对线电压)的仪表;
b) 可携式仪表;
c) 标准仪表。
本部分不涉及谐间波的(测量)内容。

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.
