LINE REACTOR SIZING PROCEDURE


Line side of AC or DC Drive

  • What is the Voltage?
  • What is the Horsepower of the Drive?

Choosing the Impedance of the Line Reactor

  • 3% impedance reactor will absorb spikes and surges and prevent nuisance tripping of drives in most applications. A 3% impedance line reactor is typical for the line side of a drive.
  • 5% impedance reactor should be chosen if harmonic content is severe or customer wants to minimize harmonics to try to meet IEEE519 recommendations. There should be a note of caution: a voltage drop will occur equal to the impedance of the reactor. Therefore, a 5% reactor will cause a voltage drop of 5%. If your line voltage is low, a 3% impedance line reactor is recommended to minimize the occurrence of a low voltage situation. A 5% impedance line reactor is typical for the load side of a drive.

Select the Proper Line Reactor by using the Selector Chart

  • Find the Horsepower Rating that you are looking for along the top row of the selector chart (below).
  • Follow that column down until you meet the voltage/impedance combination you are looking for in the left column of the selector chart.
  • Reactor part number will be in that box.
  • Using the Specification Chart in the MTE Selector brochure, verify that the full load amperage of the circuit is within the fundamental range of the line reactor.

Load Side Reactors - AC Drives - (Reactors should not be used on the output of a DC Drive)

  • What is the Voltage?
  • What is the Horsepower of the Drive?
  • What is the motor lead length?

CAUTION - If motor lead length exceeds 15 feet, especially in low horsepower applications, an LC Filter should be considered as an alternative.

Select the Proper Line Reactor by using the Selector Chart  (5% impedance is typical)

  • Find the Horsepower Rating that you are looking for along the top row of the selector chart.
  • Follow that column down until you meet the voltage you are looking for at 5% impedance in the left column of the selector chart.
  • Reactor part number will be in that box.
  • Using the Specification Chart in the Selector brochure, verify that the full load amperage of the circuit is within the fundamental range of the line reactor.

Find required voltage in left column; choose impedance; follow row to right until desired HP found.
