| Recently, due to industrial semi-conductor devices are used greatly in equipments, harmonics problems in circuits become more and more serious.To inhibit high order harmonics cause various failure in power system, and surge current on switching frequently to APFR, it is good to equip series reactors to make surge current less extreme in circuits and capacitors for exending the life of capacitors and electro-magnetic contactors. |
