SERIES REACTORS
Harmonics and surge current supressor
 |
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. |
| Class of insulation and temperature rising |
Dry type:H class, coil temperature increase below 120 oC (resistance method) Oil type:coil temperature increase below 55oC(resistance method) | |||||
| Place of installation | Indoor use | |||||
| Available temperature | Ambient temperature -20 to +45 oC (average ambient temperature is below +35 oC in 24 hours) | |||||
| Maximum current | Below 120% of rated current (For effective value of synthetic current, if there is the 5 th harmonic current in reactor circuit, it should be less than 35% against fundamental current. | |||||
