Stage Power; Choke Degree - janitza Prophi Operating Instructions Manual

Reactive Power Controller

Stage power

The stage power is the
capacitive reactive
power of a capacitor
stage. The stage power
can be set in the ex-
panded programming for each stage. In the standard
programming, the stage ratio 0:0:0:0 is indicated.
Setting range
Example: Programming stage power
With key 3 you can leaf to the stage ratio in expanded
programming. Please press key 1 to confirm. In this
example, a stage power of 10kvar is indicated for the
first capacitor stage.
Select the digit to be
changed using key 2.
The selected digit is
flashing.
Change the selected digit using key 3.
Pressing key 1 you leave the programming mode and
with key 3 you can continue leafing through the ex-
panded programming.

Choke degree

The choke degree must
be set for choked or
combined choked com-
pensation systems. The
choke degree is needed
for the exact determination of the capacitor current.
With the choke degree you lay down the switching or-
der in combined choked compensation systems. Capaci-
tor stages with a high choke degree and low choke
degree are switched alternatingly. Capacitor stages with
a high choke degree are switched in first.
If more but two different choke degrees are set, the
capacitor stages with the middle choke degrees are
switched as unchoked capacitor stages.
Attention!
To reduce the programming expenditure, the program-
ming of the first capacitor stage is taken over for all the
following capacitor stages. Nevertheless, the choke de-
gree can be changed for the following capacitor stages
afterwards.
The choke degree is given for each capacitor stage in
percent.
Setting range : 0 - 15%
Example: Programming choke degree
Please leaf to the choke degree in the expanded pro-
gramming using key 3. In this example, for the first
stage a choke degree of 5,7% is needed. For the pro-
gramming, 6% was selected.
If the choke degree for the second capacitive stage must
be programmed, you leaf to the desired capacitor stage
pressing key 2.
The selected capacitor stage is confirmed by pressing
key 1.
Select the digit to be
changed using key 2.
The selected digit is
flashing.
Change the selected
digit by pressing key
3.
Pressing key 1 you leave the programming mode and
with key 3 you can continue leafing through the ex-
panded programming.
