电磁兼容性(EMC). 第4-19部分: 试验和测量技术. 交流电源端口处频率范围为2 kHz至150 kHz的差模扰动和信号传输所致抗干扰性的试验

[中文适用范围]： IEC 61000 的这一部分涉及电气和电子设备对交流电源端口 2 kHz 至 150 kHz 范围内传导差模干扰和信号的抗扰度要求和测试方法。该标准的目的是通过应用差模干扰和向交流电源端口发送信号来测试电气和电子设备，建立一个通用且可重复的基础。本标准定义了： ?C测试波形； ?C 测试水平范围； ?C测试设备； ?C 测试设置； ?C测试程序； ?C验证程序。这些测试旨在证明电气和电子设备在高达 280 V 的电源电压（如果不使用中性线，则从相到中性线或从相到地@）和 50 Hz 或 60 Hz 频率下运行的抗扰度。传导差模干扰，例如源自电力电子和电力线通信系统 (PLC) 的干扰。注：在某些国家/地区，相线到中性点的最大电压可能高达 350 V。 IEC 61000-4-13 涵盖了谐波和间谐波的抗扰度，包括差分模式下高达 2 kHz 的交流电源端口上的电源信号传输。 2 kHz 至 150 kHz 频率范围内的发射通常同时包含差模和共模分量。该标准仅提供差模干扰和信号的抗扰度测试。建议同时执行 IEC 61000-4-16 涵盖的共模测试。 [外文原描述]： IEC 61000-4-19:2014 relates to the immunity requirements and test methods for electrical and electronic equipment to conducted, differential mode disturbances and signalling in the range 2 kHz up to 150 kHz at a.c. power ports. The object of this standard is to establish a common and reproducible basis for testing electrical and electronic equipment with the application of differential mode disturbances and signalling to a.c. power ports. This standard defines: - test waveforms; - range of test levels; - test equipment; - test setup; - test procedures; - and verification procedures. These tests are intended to demonstrate the immunity of electrical and electronic equipment operating at a mains supply voltage up to 280 V (from phase to neutral or phase to earth, if no neutral is used) and a frequency of 50 Hz or 60 Hz when subjected to conducted, differential mode disturbances such as those originating from power electronics and power line communication systems. The immunity to harmonics and interharmonics, including mains signalling, on a.c. power ports up to 2 kHz in differential mode is covered by IEC 61000-4-13. Emissions in the frequency range 2 kHz to 150 kHz often have both differential mode and common mode components. This standard provides immunity tests only for differential mode disturbances and signalling. It is recommended to perform common mode tests as well, which are covered by IEC 61000-4-16.
