For setting up the filter's main reactive power and balancing mode go to
[/Welcome/Settings/Customer set./Main settings/Main PFC/Bal.]
For setting up the filter's auxiliary reactive power and balancing mode go to
[/Welcome/Settings/Customer set./Auxiliary settings/Aux. PFC/Bal.]
The active filter can perform different reactive power tasks including balancing,
each of which require the appropriate setup.
possible tasks and shows how the filter set up should be done to implement this

Table 38: Reactive power tasks that the filter can perform
Reactive power task requirement
No requirements
Power factor compensation with inductive
power factor set point, no load balancing
(a)
required
Power factor compensation with capacitive
power factor set point, no load balancing
(a)
required
Fixed capacitive power step with a rating of x
kvar, no load balancing required
Fixed inductive power step with a rating of x
kvar, no load balancing required
Remarks:
(a)
When load balancing is required, set the 'Balance load' flag to the desired mode. The
following modes are available depending on the way the filter is connected (3-W or 4-
W)
'Disabled': No load balancing is done.
-
'L-L': Loads connected between phase only are balanced. Loads connected
-
between phases and neutral are not balanced.
- 'L-N': Loads connected between phase and neutral are balanced. Loads
connected between phases are not balanced. This mode is only available when
the filter is connected in 4-W mode.
'L-L & L-N': Both loads connected between phase and neutral as well as loads
-
connected between phases are balanced. This mode is only available when the
filter is connected in

The filter will not do any reactive power task,
regardless of the values set for cos j or static
reactive power
PFC type: Dyn. Ind.
Target cos
and 1.0
The filter will do power factor compensation up
to the cos j set point, regardless of the value
set for static reactive power(b)
PFC type: Dyn. Cap.
Target cos
and 1.0
The filter will do power factor compensation up
to the cos j set point, regardless of the value
set for static reactive power
PFC type: Static cap.
(a)
Q static: x kvar
The filter will generate x kvar reactive
capacitive power, regardless of the value set
for the target cos j
PFC type: Static ind.
(a)
Q static: x kvar
The filter will absorb x kvar reactive inductive
power, regardless of the value set for the target
