现代技术已经使交流电源整流到直流电源成为可能，使用直流驱动器的静态整流器以及交流驱动器的静态反转。整流会产生谐波电压和电流，这可能会导致问题，例如：过热和过电压导致绝缘失效；固态设备故障；以及通信干扰。在目前的工作中，作者描述了一个经过现场验证的便携式谐波测量/分析系统，用于监测这些谐波电压和电流。这个基于计算机的系统提供现场数据收集，通过快速傅立叶变换精确的谐波识别，数据分析，并通过自定义电子表格准备报告。介绍了该测量/分析系统在水泥、钢铁和碳工业中的具体应用实例
Modern technology has made possible the rectification of AC power to DC power using static rectifiers for DC drives as well as static inversion for AC drives. Rectification generates harmonic voltages and currents which can cause problems, e.g.: insulation failures due to overheating and overvoltages; malfunction of solid-state equipment; and communication interference. In the present work, the authors describe a field-proven, portable, harmonic measurement/analysis system for monitoring such harmonic voltages and currents. This computer-based system provides on-site data collection, precise harmonic identification via a fast Fourier transform, data analysis, and report preparation via a custom spreadsheet. Specific examples involving the application of this measurement/analysis system in the cement, steel, and carbon industries are presented.>
