6.6 Line reactors
The line impedance, with line reactors factored in, should be between 4% and 10% of the
short-circuit voltage.
Line inductances always need to be provided in the infeed in order to limit voltage dips and
ensure that the SINAMICS DCM functions correctly. In the most straightforward situations
this can be done by using a 4% line reactor.
The only situations in which a line reactor is not required are when the converter is supplied
as the only load by means of a separate transformer winding (converter transformer adapted
to the power level).
Where several converters are used on a transformer winding, line reactors must be used
upstream of every converter.
NOTICE
Sequence of the wiring
Semiconductor fuses should be installed in the converter system upstream of the reactor.
The break times are then achieved by the normally used semiconductor fuses
An incorrect arrangement can destroy a thyristor (short-circuit) and rupture a fuse.
