摘要
介绍了用三相交流电中任意一相的相电流与另外两相的线电压之间的相位差来测量三相异步交流电动机功率因数的方法,并对该方法的工作原理作了详细说明。使用效果表明,该方法软硬件设计简单、稳定性较好。
The paper presents the designing manner of the power factor detection of three-phase alternating current machine. It is counted by the phase difference between one-phase electric current and other two-phase voltage. The working principle of the designing manner is particularly illustrated.
