Filter reactors type INF are used to protect capacitor batteries in inductive reactive power compensators. Battery capacitors and chokes form resonant circuits that limit (filter) harmonic currents and protect batteries from these overloads This protection consists in eliminating higher harmonics that are harmful to capacitors. They are built for different battery voltages and filtration of different harmonics, which is determined by the attenuation coefficient "p" given in %.
They are most often found in two sizes:
p=7% – filter from the fifth harmonic upwards
Together with the capacitor, they form an LC filter with a resonant frequency f=189Hz.
p=14% – filter from the third harmonic upwards
Together with the capacitor, they form an LC filter with a resonant frequency f=134Hz.

CAPACITOR BATTERY WITH REACTORS
A battery of capacitors with reactors is a device whose task is to compensate for reactive power in power grids. The reactive power compensation process involves the introduction into the electrical network of a certain amount of inductive or capacitive reactive power. The inductive reactive energy present in the network is compensated by capacitance using capacitors, whose work is controlled by an automatic regulator. Capacitive reactive energy present in the network is compensated by induction using compensating chokes. In the situation of significant alternating voltages in the network and the phenomenon of battery resonance with the network, capacitor batteries with chokes are used. A filter reactor is an element that is designed to filter changes in current intensity to eliminate the risk of a short circuit within the network. The role of chokes is to protect capacitors from destruction.
