Tuned Filter Bank

FT2000 Series

Medium & H.V. Automatic Tuned Filter Bank

The FT2000 Automatic Passive Harmonic Filters consist of capacitors connected in series with a reactor. Capacitors produce reactive power at the filter's fundamental frequency. The circuit is designed to achieve the required power factor correction. The reactor's inductance is selected so that the filter forms a very low impedance series resonant circuit at the harmonic frequency. This ensures that a high proportion of the harmonics enter the filter. A typical harmonic filter consists of three series resonant circuits tuned to the most common harmonics (5th, 7th and 11th harmonics). The filters are housed in steel cubicles. Each consist of a contactor, thermal over current device, reactor and capacitor. The unit is generally connected to the fused feeders on the main distribution board.
