本文件根据ISO/IEC？22237？1中关于“可用性”、“物理安全性”和“能源效率实现”的标准和分类，阐述了数据中心的供电和配电。 本文件规定了以下方面的要求和建议: a） 数据中心的电力供应； b） 数据中心内所有设备的配电系统； c） 电信基础设施连接； d） 防雷； e） 用于测量配电系统沿线各点的功耗和电能质量特性的设备，以及这些设备与管理工具的集成。 安全和电磁兼容性（EMC）要求不在本文件的范围内，并包含在其他标准和法规中。然而，本文件中提供的信息有助于满足这些标准和法规。 第4条涵盖了数据中心与本文件的一致性。 电网使用的数据中心储能或替代能源的使用不在本文件的范围内，将在未来的规范中予以考虑。

This document addresses power supplies to, and power distribution within, data centres based upon the criteria and classifications for “availability”, “physical security” and “energy efficiency enablement” within ISO/IEC？22237？1. This document specifies requirements and recommendations for the following: a) power supplies to data centres; b) power distribution systems to all equipment within data centres; c) telecommunications infrastructure bonding; d) lightning protection; e) devices for the measurement of the power consumption and power quality characteristics at points along the power distribution system and their integration within management tools. Safety and electromagnetic compatibility (EMC) requirements are outside the scope of this document and are covered by other standards and regulations. However, information given in this document can be of assistance in meeting these standards and regulations. Conformance of data centres to the present document is covered in Clause？4. The use of the data centre stored energy or alternate sources to be used by the grid is not in the scope of this document and is for consideration in future specifications.
