标准摘要
[中文适用范围]： IEC 60027的这一部分适用于电能的产生、传输和分配。它给出了数量和单位的名称和字母符号。此外，还给出了多个下标及其连续的规则。 IEC 60027 的这一部分是对 IEC 60027-1 的补充。因此，IEC 60027-1 中已经给出的字母符号只有在发电、输电和配电领域具有特殊含义或在该领域使用时带有特殊下标时才会重复。 [外文原描述]： IEC 60027-7:2010 is applicable to generation, transmission, and distribution of electric energy. It gives names and letter symbols for quantities and units. In addition, rules for multiple subscripts and their succession are given. It is an addition to IEC 60027-1. Therefore letter symbols already given in IEC 60027-1 are repeated only if they have a special meaning in the field of power generation, transmission, and distribution or if they are used in this field with special subscripts.
