The exact value depends upon the efficiency of the drive, the motor and the entire application. ** Power loss at 25C/50 Hz, considering a typical harmonic spectrum of a motor drive with B6U rectifier bridge. 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 higher impedance 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.
