Description
Voltage threshold (in % of
nominal voltage) that must
be exceeded or fallen be-
low to activate VFRT re-
gion 1 and its associated
current inrush mode.
- > 100 % ... Region 1 is
used as the HVRT re-
gion.
- < 100 % ... Region 1 is
used as the LVRT re-
gion.
Setting condition:
Threshold R1 > Threshold
R2 > Threshold R3
Multiplication factor (k-
factor) for the positive-se-
quence system reactive
current in region 1.
Only applied with current
inrush mode "Active Sym-
metric Current" and "Act-
ive Asymmetric Current".
Multiplication factor (k-
factor) for the negative-
sequence system reactive
current in region 1.
Only applied with current
inrush mode "Active
Asymmetric Current". If
an asymmetrical feed is
required, this is usually set
to the same value as "k-
factor Positive Sequence".
If symmetrical supply is
required, this is set to 0.
