本文件是关于电气和电子设备对来自150 kHz~80 MHz频率范围内有意和/或无意宽带信号源产生的电磁骚扰的传导抗扰度要求。
本文件的目的是建立一个通用的基准,以评估电气和电子设备交流电源端口在遭受有意和/或无意宽带信号源产生的传导骚扰时的抗扰度。本文件规定的试验方法描述了评估设备或系统对已定义现象的抗扰度的一致性方法。
不具备至少一个交流电源端口的设备不在要求之列。不准备连接到交流电源配电网络上的电源端口认定为非“交流电源端口”,因此也不在要求之列。
本文件仅适用于额定输入电流≤16 A的单相设备;多相设备和/或额定输入电流大于16 A的单相设备的宽带骚扰适用方法还在考虑中。
注: 按照IEC GUIDE 107里描述的,本文件是为产品委员会所用的基础EMC出版物。正如IEC GUIDE 107声明的,产品委员会负责确定是否采用本抗扰度标准,如果采用,他们负责确定适当的试验等级和性能判据。IEC/TC 77和其分技术委员会愿与产品委员会合作,来评估其产品的特定抗扰度试验电平。

This part of GB/T 17215.3 specifies the terms and definitions, classifications, technical requirements, accuracy classes and test methods of static meters connected via electronic transformer (hereinafter referred to as “meters”).
This document is only applicable to newly manufactured meters which have small (signal) analog input and are installed in the networks with a reference frequency of 50Hz or 60Hz to measure the a.c.electric energy and applies to their type tests only.
This document is applicable to the meters consisting of elements such as measuring unit and display enclosed together in a meter case.
This document may be used as reference for meters that have a small (signal) analog input only in the current circuit.
This document is not applicable to meters with digital inputs.
NOTE The transformers intended to connected to the meter refer to GB/T 20840.7-2007, GB/T 200840.8-2007 and DL/T 1155-2012.
