WebAn impedance value too low may not limit peak current. Too high of an impedance may reduce input voltage. Allen-Bradley line reactors offer two impedance ratings. 3% Impedance Rated Reactors to Reduce Nuisance Trips Allen-Bradley line reactors rated at 3% are typically sufficient to absorb line spikes and motor current surges and will help Weba gapped iron-core reactor experiencing less severe inrush compared with a transformer. Gapped iron-core reactors can be used as three single-phase units or three-phase units with a three- or five-legged core construction. The five core legs result in a zero-sequence impedance that is equal to the positive-sequence impedance.

WebThat is, if the impedance of a Line Reactor is 10 ohms at 60 Hz, then at the 5th harmonic (300 Hz), the impedance is 50 ohms. If the inductance (L) is increased, then the impedance will increase proportionally. This increase in Line Reactor impedance will reduce the current in the line. The higher the frequency (Hertz) is, the greater the
