摘要
文章介绍了异步电动机绕组阻值在线测量中,由隔直流电容引起异步电动机的自激问题。分析了产生的原因,并提出避免异步电动机自激问题的方案及电容选取方法。
It is introduced that series capacitors may arouse self-excitation while online winding resistance measurement of an asynchronous motor. It is analyzed how it arises,and then the countermeasure and selection of series capacitors is put forward.
