Line Load Reactors

A “choke” is the common name given to an inductor that is used as a power supply filter element. They are typically gapped iron core units, similar in appearance to a transformer. The current in an inductor cannot change instantaneously; that is, inductors tend to resist any change in current flow. This property makes them good for use as filter elements, since they tend to “smooth out” the ripples in the rectified voltage waveform.

Whether you are using reactors on the input or output of a VFD the best performance results will always be achieved using reactors which are fully compensated for the harmonics which are present. This assures maximum inductance and thus best attenuation of harmonics with maximum current surge protection. Harmonic compensated reactors have proven to be the most cost effective solution to a wide variety of typical VFD application problems. Use them on the input or output of your drives to improve the total system performance and reliability.

0.5 KW to 3000KW


DIFFERENCE BETWEEN “LINE” AND “LOAD” REACTORS:

Line reactors are used the “line side” or input of a variable frequency drive (i.e. where three-phase voltage comes into the VFD.
Load reactors are used on the “load” side of variable frequency drive (between the drive and the motor). Load reactors are a new, more effective reactor technology and are ideal for harmonic compensation.
