认为谐波源来自系统侧，除了非线性负荷外，主要是由大型电力变压器激磁电流所造成。

The harmonic comes from power system side, which is caused mainly by exciting current of the large capacity transformer besides the nonlinear loads.

除了这些优点外，喇叭选择器通过减少或平衡负荷还有助于保护扩音器免受损害。

Beyond these benefits, speaker selectors also help to protect the amplifier from damage by reducing or balancing the load.
