高压电气设备介质损耗的一种微机测试

A Micro-Computer Measurring System of the High-Voltage Equipment Loss-Tangent Factor

本文阐述了用微机测试高压电气设备介质损耗的意义及目的.并对实现的方法和所存在的一些问题做了介绍.其中,以“自由轴”测量方法为主,详细地介绍了它的原理、数学模型的建立,并对实现方法的硬件电路做了简要介绍.

In this paper,The micro - computer measurring system of high - voltage equipment loss - tangent factor has been discussed,and realization methode and some problems has been also introduced. Taking the free -axis methode as an important exemple,the author intensively introduced its principle, and mathematics mode. Finally the practice hardware circiut used in this system has been briefly introduced.
