标准摘要
[中文适用范围]： 本技术报告记录了在制定IEC 60555中采用的参考阻抗以及现在部分IEC 61000-3中采用的参考阻抗时所获得的信息和考虑的因素。此外，还提供了与每相服务电流容量≥100A相关的公共供电网络的阻抗信息。 [外文原描述]： IEC;TR 60725:2012, which is a technical report, records the information that was available and the factors that were taken into account in arriving at the reference impedances that were incorporated in IEC 60555 and which are now incorporated in some parts of IEC 61000-3. In addition, information is given on the impedances of public supply networks associated with service current capacities =100 A per phase. The third edition includes brings two mainly significant technical changes with respect to the previous edition: - a new survey and other data from countries with public supply networks operating at 60 Hz have been included; and - recommendations that were applicable to 50 Hz systems are now mirrored by new recommendations that are relevant to 60 Hz systems.
英文名称Consideration of reference impedances and public supply network impedances for use in determining the disturbance characteristics of electrical equipment having a rated current ≤75 A per phase
