The harmonic comes from power system side, which is caused mainly by exciting current of the large capacity transformer besides the nonlinear loads.
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 results of experimental operation of APF in the harness of harmonic pollution from the exciting power source for heavy-hydronium accelerator are given.
最后，给出了重离子加速器励磁电源在谐波治理方面的实验运行结果。
3
It is concluded that it is better to use harmonic wave as exciting wave than to employ symmetrical trigonometric wave.
