Band-pass electronic filter

passiveharmonicthree-phase

DAQI ® passive harmonic filter is specifically engineered to mitigate harmonic currents created by non-linear loads. It is currently available from 1.5 to 250kw and it improves power quality by simultaneously reducing harmonics and improving true power factor. The advanced DAQI ® PHF design delivers superior performance compared to a traditional harmonic filter by reducing harmonic current distortion by 80% (typically to 5% or less at full load), corrects true power factor to over 95%, and meets IEEE 519 harmonic requirements when operated within designed parameters. DAQI ® PHF consists of reactors and capacitors in an LCL arrangement designed to reduce a broad range of harmonics associated with variable frequency drives and other three phase rectifiers. Compatible design with Danfoss VLT® Series Drivers. IEEE 519 IEC61000-3-2(up to 16 A) IEC61000-3-12 (between 16 and 75 A) IEC61000-3-4 (above 75 A) Thdi : THDi98.5% (100% load);
