Mains chokes
Allocating the mains reactors is done according to the rated input
currents of the frequency inverter (without upstream mains
reactor).
Figure 129: Line reactors DEX-LN…
h
If the frequency inverter is operating at its rated current
limit, the maximum possible output voltage of the
frequency inverter (U
2
) is reduced to around 96 % of the
mains voltage (U
LN
) due the mains chokes at a u
K
value of
around 4%.
h
Line reactors reduce the magnitude of the current
harmonics up to about 30 % and increase the lifespan of
frequency inverters and upstream-connected switching
devices.
