The results also indicate that when special filters are connected to secondary three-phase system, the primaryharmonic currents decrease by about 28% than by using conventional two-phase filters.
结果还表明，当在二次侧三相系统接入文中提出的特殊滤波器时，谐波电流比用常规两相滤波器降低约28%。

This is the primary reason I choose sweeps for harmonic distortion testing.
这是主要的原因，我选择谐波失真测试扫荡。

The harmonic compensation currents proportional to the harmonic current in the primary winding, which is detected real-timely, are injected to the multiple secondary winding of the transformer.
