WebIV. Reactors Percent Impedance: 3% or 5% Line and load reactors are classified by their percent impedance (denoted as percent IZ or %IZ), which is the voltage drop due to impedance, at the rated current, expressed as a percent of rated voltage. The most common line reactors have either 3% or 5% impedance. 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 slush backgroundWebReactors of Siemens Energy are highly economically efficient and enhance grid stability.

"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 " - Reactor impedance
