Description of filter reactor ：
Filter reactor together with capacitors can combine harmonic circuit to reduce the harmonic current in the system , mainly 3rd , 5th , 7th , 11th , 13th and higher . Filter reactor can be installed by parallel or serial connection .

Function of filter reactor ：
PWM Rectifier LCL reactor , carrier frequency: ≥2K working Frequency: 50HZ Phase: 3
Harmonic contains the VFD’s interference for the power grid , harmonics mainly 3、5、7、9、11、13、15、17、19 , output side harmonics mostly 5~10Khz high frequency harmonics .

Insulation resistor : winding-ground , cross core screw-ground 500VDC , insulation resistance≥100MΩ ; reactor noise:＜65db (1 meter from reactor)
Protection:IP00; Insulation:F/H , Standard:IEC289;GB10229-88 (eqv IEC289:1987)

Application of filter reactor ：
Wind power generation, photovoltaic ,VFD and UPS
