Experiment results showed that the correction device of power factor could realize high power factor, low harmonic distortion and low ripple of output voltage.

通过实验结果表明，单级功率因数校正装置可以实现较高的功率因数、较低的总谐波畸变，而且输出电压纹波小。

The power system harmonic is the voltage sine wave of power system get distortion; electric locomotive power will have 0 to 50 harmonics.

电力系统的谐波是电力系统电压正弦波形产生畸变，电力机车用电会产生0次到50次谐波。

However, the utility source for a plant may contain additional harmonic voltage distortion arising from external sources.

然而，对工厂实用电源可能包括由外部电源引起的额外的谐波电压畸变量。
