Circutor RX-15-400 Three-Phase Reactor Detuned Filter

CIRCUTOR has a standard range of rejection reactors p = 7 %, with a resonance frequency of 189 Hz for 50 Hz networks (or on-demand 227 Hz for 60 Hz networks). This is the most frequent tuning value to avoid any resonance of the 5th harmonic and above. The set of capacitors-reactors absorbs part of the current of the 5th harmonic and acts as a rejection filter for higher frequencies. In some installations, other values of p % are required, for example 5.6 % (210 Hz), 6 % (204 Hz), 14 % (134 Hz), etc. CIRCUTOR can build reactors on demand, which will be adapted to any power rating, p %, voltage, and frequency. Low-powered reactors, R type, are built with plates with low losses and are coiled with a copper conductor. The connection is achieved with adequate terminals. In the case of higher power ratings, RB reactors are used, with a magnetic plate nucleus and multiple steel cores, which offer excellent characteristics and a low loss ratio. Aluminum band coils are used (or copper band, on-demand) and the input and output connections run through a plate. Both R and RB type reactors have a vacuum varnish sealing to increase the insulation, providing greater mechanical resistance and reduce the level of noise.

The rejection reactors of the R / RB series have been specially designed for their use in capacitor banks in installations with a high harmonic content. The reactors must be connected in series to each capacitor for the adequate protection of capacitors and to avoid the resonance effects in the installation.
