A 3% impedance reactor absorbs transients and prevents nuisance tripping of drives in most applications and is typical for the line side. A 5% impedance reactor can be used if the harmonic content is severe or if IEEE519 recommendations should be met. The reactor impedance magnitude is said to be equal to the voltage drop. | A 3% impedance reactor absorbs transients and prevents nuisance tripping of drives in most applications and is typical for the line side.
