介质损耗测试方法的研究

STUDY ON THE MEASURING METHOD OF DIELETRIC LOSS

以傅立叶级数分离基波相位的方法为依据，采用先进的单片计算机技术，提出了一种新的测量方法．理论分析和仿真结果表明，这种数字测量方法检测方便，系统组成简单，智能化程度高，适用于介质损耗角正切较大的简易测量．

This paper applies Fourier series to detach the fundamental waves phase, adopts advanced micro controller technique, and raises a new method. Theoretical analysis and emulation result indicate that this digital measuring method is fit for some simple measurment for which the dieletric loss angle is bigger. Its merits are the convenience in measuring, simple system composition, and the high degree of intellect. At last, this paper gives hardware structrual diagram of this digital measuring system.
