The harmonic filter (HFR) includes a secondary absorption circuit consisting of main inductor L1 and L2, inductor L3, and capacitor C combination. The unit can be equipped with transformer TA and branch contactor KM, and the absorption circuit needs special adjustment to improve the harmonic current of the 5th and above. The circuits with a fundamental frequency of 50Hz and 60Hz have different fundamental frequencies. The filter performance varies with the load function. Under rated load, the performance of HFR filter THiD ≤5% or ≤10%.
Applicable to a variety of front-end is six-pulse rectifier power equipment harmonic current to reduce the specified limit below. Daily Electrical Load, nonlinear load accounts for a large part.
The HFR harmonic filter can quickly and conveniently upgrade the standard motor drive to the low harmonic drive.
The HFR harmonic filter helps to reduce the overload caused by the load harmonic current and the overheating of the power infrastructure, thus making full use of the power system. The low harmonic current reduces the risk of system resonance and the potential outage of sensitive electronic equipment.
