Feature
In the recently years 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 inrush current on switching frequently in the application of automatic power factor regular (APFR), it is good to equip series reactors to limit harmonics current in circuits and inrush current to capacitors for extending the life of capacitors and electro-magnetic contactors.
