Benefits of Using RL Line/Load Reactors

MTE RL reactors help keep your equipment running longer by absorbing many of the power line disturbances which otherwise damage or shut down your inverters, variable speed controllers, or other sensitive equipment. They are the modern technology solution to inverter and drive application problems. MTE reactors are harmonic compensated and IGBT protected to assure optimum performance in the presence of harmonics. They are very effective at reducing harmonics produced by inverters and drives, and in most cases will help you to meet IEEE 519. Use our harmonic compensated reactors on either the input or output of an adjustable speed drive/inverter. There is no need to derate our “harmonic compensated” reactors for harmonics.

Impedance Ratings

3% impedance reactors are typically sufficient to absorb power line spikes and motor current surges. They will prevent nuisance tripping of drives or circuit breakers in most applications.

5% impedance reactors are best for reducing harmonic currents and frequencies. Use them when you must comply with IEEE 519, to reduce motor operating temperature, or to reduce motor noise.


% Impedance =[{I<sub>(50/60 Hz fundamental)</sub>*2*pi*f*L*SQRT(3)}/{V<sub>(L-L)</sub>}]*100

NOTE: The true effective impedance of the reactor changes with actual fundamental current.
