Electromagnetic compatibility—General—Historical rationale for the limitation of power-frequency conducted harmonic current emissions from equipment,in the frequency range up to 2 kHz
IDT IEC/TR 61000-1-4:2005
全国电磁兼容标准化技术委员会(SAC/TC 246)
《电磁兼容 综述》的本部分为指导性技术文件，回顾了电网上在2 kHz内工频谐波电流传导发射的来源及其影响，说明了IEC 61000-3-2:2000+AMD1:2001以及IEC 61000-3-12:2004中设备现有发射限值的推导过程。
本部分中的概念适用于所有低压交流供电系统，但数据仅适用于欧洲230 V/400 V、50 Hz供电系统。
