The no-load power factor 空载功率因数
In the no-load test of transformer, because of the low power factor and non-sinusoid current waveform, the high precision measurement is difficult.
变压器的空载试验中，由于功率因数低，空载电流不是正弦信号，高精度测量其有功功率具有一定的难度。
It can improve the power factor of the motor when it is under low load or no load running.
