标准摘要
[中文适用范围]: IEC 60255的本部分基于IEC 61000-4-16中描述的概念,在适用时参考该出版物,并规定了电力系统保护的测量继电器和保护设备的工频抗扰度试验的一般要求,包括控制、监控和处理与这些系统一起使用的接口设备。测试的目的是确认被测设备 (EUT) 在通电并受到施加到直流状态输入的短持续时间、传导、共模和差模电源频率干扰时,在 EUT 的额定频率下能够正常运行,例如 16/3 Hz、50 Hz 和 60 Hz。本标准不包括变电站之间的引导线方案的测试。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。本标准的目的是说明: ——所用术语的定义; - 测试严重程度; - 测验设备; - 测试设置; ——测试程序; - 验收标准; - 测试报告。 [外文原描述]: Specifies general requirements for power frequency immunity tests for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems. The objective of the tests is to confirm that the equipment under test will operate correctly when energised and subjected to short duration, conducted, common and differential mode power frequency disturbances. Is based on IEC 61000-4-16.
