中文摘要: 提出了一种在0.1 Hz交流试验电压下的介质损耗测量方法。在准同步和谐波分析两种数据处理方法的基础上,采用准同步谐波分析法对测量数据进行处理,克服了随机干扰信号和谐波分量在测量过程中对测量精度的影响,使测量精度达到了测试要求。
Abstract:In order to make the 0.1 Hz very low frequency withstanding voltage system can be used to measure the insulation material and evaluate the status of aging,the tanδ test must be done under 0.1 Hz test voltage.A new method of tanδ measurement is proposed.By analyzing the principles of quasi-synchronous sampling method and harmonic analysis method in details,the quasi-synchronous sampling harmonic analysis method is used to deal with the data.This method can overcome the influence of harmonic component and random signal,and make the measurement system precision meet the need of measurement.
keywords: harmonic analysis method quasi-synchronous tanδ
