Damping resistor for HFD line reactors
3.8.4.1
Description
Using a damping resistor
In some systems, oscillations can be generated which place an impermissibly high strain on
the insulation systems of the motors and converters involved. Connecting a damping resistor
to the additional winding of the HFD line reactor is an effective means of damping just such
system oscillations. Use of the 800 W damping resistor is preferable.
Note
Recommendation
Use an Active Interface Module as line connection component for new plants and systems
equipped with Active Line Modules.
