标准范围

IEC 61557-6:20 19作为IEC 61557-6:20 19 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61557-6:20 19规定了适用于测试安装在TT、TN和IT系统中的剩余电流装置（RCD）保护措施有效性的测量设备的要求。本文件的目的不是根据RCD的产品标准对其进行验证。IEC 61557-6:20 19取消并取代了2007年发布的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)增加了测试新型RCD的要求；b)增加B类区域协调制度的要求（原附件B）；c)增加关于建议跳闸时间的新附件B；d)结构与整个IEC 61557系列的结构对齐。

IEC 61557-6:2019 is available as IEC 61557-6:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61557-6:2019 specifies the requirements applicable to measuring equipment for testing the effectiveness of protective measures of residual current devices (RCD) installed in TT, TN and IT systems. It is not the purpose of this document to verify the RCD according to their product standards. IEC 61557-6:2019 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) addition of requirements for testing a new type of RCD;
b) addition of requirements for type B RCDs (former Annex B);
c) addition of new Annex B on recommended tripping times;
d) alignment of the structure with that of the whole IEC 61557 series.
