摘要
就电力系统中常用的一种由R、L、C组成的阻抗设备的Z－f、R－f 频率特性的自动化测量方法、测试精度及后期的数据处理进行了研究与探讨，设计出带有反馈检测系统的高输入阻抗的峰值检测电路。
：In this paper we deliberate the method used to measure automatically the Z－F， R－F frequency property of a impedance equipment consisting of R L C， which is frequently used in power system，and calculate the circuit＇s surveying precision and process its datum． We also design a high input impedance peak check circuit that uses feedback－checking system．This circuit ha some practicability．
