Harmonic Filter
Harmonic filter are designed for use in places where generating large amounts of harmonics in the grid and where high quality power are required. Usually installed in the main distribution cabinet or next to the auxiliary distribution cabinet. The load which generated the harmonics includes: DC drive, frequency inverter, uninterruptible power supply (UPS), all kinds of dimming lights, electric arc furnace, arc welding equipment. In the same transformer network, it is not allowed to use the harmonic filter and ordinary capacitor group at the same time or period.
