Harmonic Filter Reactor

It provides low impedance path for the harmonic currents.

It can be achieved by the series connection of a filter reactor with a capacitor bank

It eliminates harmonic frequency

If several harmonic frequencies need to be eliminated, a number of filters with different resonance frequencies will be connected to the bus system, for instance the 3rd, 5th and 7th harmonic of the fundamental frequency (50Hz or 60Hz).
