The results also indicate that when special filters are connected to secondary three-phase system, the primary harmonic 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。
