IEC 61000-2-2:20 02+A1:2017涉及0 kHz至9 kHz频率范围内的传导干扰，特别是对于电源信号系统，可扩展至148.5 kHz。它给出了公共低压交流的兼容性级别。标称电压高达420 V、单相或690 V、三相、标称频率为50 Hz或60 Hz的配电系统。规定了公共低压供电系统中可能预期的电磁干扰类型的兼容性水平，以指导:-为进入公共供电系统的干扰发射设定的限值；-产品委员会和其他机构为暴露于公共供电系统中存在的传导干扰的设备设定的抗扰度限制。该合并版本由第二版（2002年）及其修正案1（2017年）组成。因此，除本出版物外，无需下令修订。

IEC 61000-2-2:2002+A1:2017 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. It gives compatibility levels for public low voltage a.c. distribution systems having a nominal voltage up to 420 V, single-phase or 690 V, three-phase and a nominal frequency of 50 Hz or 60 Hz. Compatibility levels are specified for electromagnetic disturbances of the types which can be expected in public low voltage power supply systems, for guidance in: - the limits to be set for disturbance emission into public power supply systems; - the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances present in public power supply systems. This consolidated version consists of the second edition (2002) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.
