Overview of the line reactors
Line reactors limit line harmonics to permissible values. For this reason, line reactors should
always be used.
They must be used in conjunction with Active Line Modules as an energy storage device.
HFD line reactors have an additional winding, to which a separate damping resistor must be
connected.
This dampens any possible system oscillations in converter systems to non-critical values.
This results in increased operational reliability and extends the service life.
Depending on the parasitic resonance points, as a result of cable capacitances and line
supply characteristics, system oscillations can occur with voltage amplitudes that can
possibly reduce the service life of components.
Note
Recommendation
Use an Active Interface Module as line connection component for new plants and systems
equipped with Active Line Modules.
The line reactors listed below are available for use with Line Modules.
