标准摘要
[中文适用范围]： IEC 61000-3 的本部分适用于使用频率范围为 3 kHz 至 525 kHz 的信号来传输公共供电系统或客户场所内低压电气装置信息的电气设备。它规定了分配给不同应用的频带（如果适用）、工作频带内终端输出电压的限制以及传导和辐射骚扰的限制。它还给出了测量方法。它规定了 3 kHz 至 400 GHz 频率范围内的干扰限值。它没有指定信号调制方法、编码方法或功能特征。不包括环境要求和测试。注：符合本标准并不意味着允许与客户安装之外的位置或通过公共供电系统与其他客户建立通信，否则这是不允许的。 [外文原描述]： Applies to electrical equipment using signals in the frequency range from 3 kHz up to 525 kHz to transmit information on low-voltage electrical installations, either on the public supply system or within customers' premises. Specifies frequency bands allocated to different applications (where appropriate), limits for the terminal output voltage in the operating band and limits for conducted and radiated disturbance. It also gives the methods of measurement. Specifies disturbance limits in the frequency range from 3 kHz up to 400 GHz.
