摘　　要：本文以四导体静电独立系统为例,依据部分电容原理给出三种测量方案,分别为无短接法、两路短接法和一路短接法,并以双馈异步发电机中寄生电容测量问题为例,对三种测量方案进行了比较。分析表明,对于各部分电容值差距较大的多导体系统,从测量的简便性和数据准确度来看应采用无短接法。The measurement of partition capacitance in electrostatic independent multiple conductors system is an experiment in Engineering Electromagnetic Field courses, and which is also a problem frequently appeared in elec- trical engineering. Based on the theory of partition capacitance, three measurement methods are proposed in the case of four-conductor system. They are respectively named as no-short circuit method, two-line short circuit method and one-line short circuit. In order to compare the three methods, the partition capacitances of a double-fed asynchronous generator are measured. The result shows that considering the measurement simplicity and result accuracy, no-short circuit method is recommended.
