标准摘要
[中文适用范围]: IEC 61000 的这一部分提供了用于测量高功率瞬态电磁参数引起的响应的方法和手段(例如仪器)的基本描述。这些响应可包括: - 电场 (E) 和/或磁场 (H)(例如,被测系统内的入射场或入射加散射场); - 电流/(例如,由瞬态场或被测系统内感应的电流); - 电压V(例如,由瞬态场或被测系统内感应的电压); - 电缆或其他导体上感应的电荷 Q。注:导体上的电荷 O 是可以在任何频率下定义的基本量。然而,电压V是一个定义的(例如,次级)量,其仅在低频下有效。在高频下,电压不能定义为电场的线积分,因为该积分与路径相关。因此,对于非常快的上升脉冲(具有大的高频频谱内容),使用电压作为测量可观测值是无效的。在这种情况下,电荷是需要测量的量。这些测量量通常是复杂的与时间相关的波形,可以通过几个标量参数或“可观测值”来近似描述。这些参数包括: - 响应的峰值幅度, - 波形上升时间, - 波形下降时间(或持续时间), - 脉冲宽度,以及 - 从波形获得的数学定义范数。本国际标准提供了有关这些波形的测量和特征参数的数学确定的信息。它不提供有关测试的具体级别要求的信息。 [外文原描述]: Provides a basic description of the methods and means (e.g., instrumentation) for measuring responses arising from high-power transient electromagnetic parameters. These responses can include: - the electric (E) and/or magnetic (H) fields (e.g., incident fields or incident plus scattered fields within a system under test); - the current I (e.g., induced by a transient field or within a system under test); - the voltage V (e.g., induced by a transient field or within a system under test); - the charge Q induced on a cable or other conductor. These measured quantities are generally complicated time-dependent waveforms, which can be described approximately by several scalar parameters, or "observables". These parameters include: - the peak amplitude of the response, - the waveform rise-time, - the pulse width, and - mathematically defined norms obtained from the waveform. This International Standard provides information on the measurement of these waveforms and on the mathematical determination of the characterizing parameters. It does not provide information on specific level requirements for testing. It has the status of a basic EMC publication in accordance with IEC Guide 107.
