摘要
本文介绍了测功机作为实验负载的基本原理．它本身就是一台定子可以偏转的并励直流发电机．文章对实验时常出现的几种情况作了理论分析，并提出了解决问题的具体方法．
This paper presents the primary operating principle of a power tester which, origirially ashunt DC-generator itself with a swing stator, acts as an experimental 1oad. The problemsoccured in experiments are analyzed ttheoretically and thesolution to these problems are givenin this paper.
