标准摘要
[中文适用范围]： IEC 60255的本部分适用于电力系统保护的测量继电器和保护设备，包括与这些系统一起使用的控制、监视和过程接口设备。该标准规定了工业场所使用的测量继电器和保护设备的电磁兼容性基本要求。变电站和发电厂使用的测量继电器和保护设备可能需要更高的抗扰度测试水平。对于不包含电子电路的设备，例如机电继电器，不需要根据本标准进行测试。本标准规定的要求适用于新状态下的测量继电器和保护设备，规定的所有试验仅为型式试验。 [外文原描述]： IEC 60255-26:2008 is applicable to measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems; it specifies the essential requirements for electromagnetic compatibility for measuring relays and protection equipment intended to be used at industrial locations. The main difference of this new edition with respect to the previous one concerns the references to IEC 61000-4 and to CISPR 22.
