Harmonics reduction
Line reactors are a cost-effective way for the limitation of mains harmonics. The harmonics reduction capability is related to the reactor impedance. A higherimpedance translates directly into lower harmonic currents, but of course also into a larger component with a higher voltage drop − and vice versa.4% impedance reactors like RWK 212 provide an excellent cost/benefit ratio and are particularly beneficiary in the most diverse motor drive applications.The table below shows various reactor impedance values and their calculated effect in terms of harmonics reduction.
