Description

These LIFASA capacitors are made with open three-phase circuit (six terminals) for use in static capacitor banks (control by thyristor) and designed to be connected in series with INRS or INAS reactors, in order to build up low tuning (fr = 189 Hz) Harmonic Protection Filters (Capacitor rated powers indicated in the table, are achieved when connected to the reactors). FMLFS capacitors have been specially developed taking into account that, when connected to the reactors, they work at a voltage higher than the supply voltage. Inductance value of INRS and INAS reactors and capacitance value of FMLFS capacitors are specially calculated to ensure that, when connected in series, the reactive power of the filter is as given on the name plate.
