摘要
分别采用实地法和虚地法测量电感、电容的阻抗特性,通过分析比较,发现采用实地法测量电感、电容的阻抗特性,所测得的阻抗、阻抗角测量值与理论计算值相比较误差较大;而采用虚地法测量电感、电容的阻抗特性,所测得的阻抗、阻抗角测量值与理论计算值相比较误差较小.
In this paper,the impedance characteristics of inductance and capacitance are measured respectively by using the methods of the field measurement and the virtual ground measurement. By analysis and comparison,the authors find that the error between the value of the measured impedance and impedance angle and the value of theoretical calculations is great by use of the method of the field measurement,while the corresponding error is small by use of the method of the virtual ground measurement.
