Installation of A Compensation System :
Example: There is a system that has Cosj=0,80 and 50kVA total
pwer. What are the total capacitor power that is needed and C/k
value?
Solution: If total power S=50kVA,
P=SxCosj=50x0,80=40kW
Cosj=0,80 value is reached to target Cosj=1,00 value by
using a multiplier that is taken from “Target Cosj Table”. Multiplier that
is taken from table is 0,75. Reactive power;
Q=PxMultiplier=40x0,75=30kVAr is found. System’s
reactive power before compensation, equals reactive power that is
reached with target cosj=1,00 value. Like in this example, system’s
reactive power is 30kVAr.
Current transformer ratio:
50kVA / (220x3) =75A it is selected as a near value to the
upper standart 100/5.
For 12 steps, if we think this way 1 2 2 2 2 2 2 2 2 2 2 2; in
total 23 electrical steps are obtained.
First step’s capacitor power 30kVAr / 23 = 1,3kVAr is found.
Nearest value 1,5kVAr or 1kVAr is selected. If we also think %20
tolerance, we choose 1kVAr.
1 2,5 2,5 2,5 2,5 2,5 2,5 2,5 2,5 5 5 5 = 36kVAr is found.
C/k= 1kVAr / (100/5) =0,05 is found. C/k value is selected 0,05 to
adjust.

D- Warnings and Explanations :
1- Over Current Alarm: If measured seconder current value of
current transformer is bigger than adjusted over current value, “Over
Cur.” lights. If over current alarm is active and this continues 60sec.,
the alarm is turned on.
2- Low Current Alarm: If measured seconder current value is lower
than 50mA, “Low Cur.” lights.
3- Over Voltage Alarm: If measured voltage value is bigger than
adjusted over voltage value, “Over Vol.” lights. If over voltage alarm is
active and this continues 60sec., the alarm is turned on.
4- Insufficient Compensation Alarm: If the controller switches on all
steps and it does not reach to system’s target cosj value, it lights
insufficient compensation alarm. If this continues 60sec., “
“
lights and the alarm is turned on.
5- Over Compensation Alarm: If the controller switches off all steps
and its cosj value is bigger than system’s target cosj value, it lights
over compensation alarm. If this continues 60sec., “
“ lights and
the alarm is turned on.
General Rules for Compensation
10
1- Current transformer that is connected reactive power controller
must have .../5A ratio.
2- After current and voltage connections of the controller is made
carefully according to connection scheme, Cosj and C/k values must
be adjusted according to system’s need.
3- Capacitor steps must be connected low to high order.

3- Capacitor steps must be connected low to high order.
4- When system is energized firstly, manuel mode is selected for
determining true direction of current inputs. Normally phases’
reactive loads are inductive. If the controller shows capacitive
reactive, current transformer output pins must be changed.
Warning: When loads is changed rapidly in a system, to shorten
switch on time causes shorter life for contactors and
condansators. So this is not recommended. In these systems, the
best solution is local or individual compensation.
Warning: No responsibility is assured by the manufacturer for
consequences resulting from wrong installation of this device
which is not consulted by the user guide.
F- Computing C/k Value:
C/k adjustment, determines least power that is wanted
to control. It equals first step’s capacitor power, divide by current
transformer ratio.
Example: There is a system which first step’s capacitor power is
1 kVAr. If current transformer ratio is 100/5, what is C/k value that
is needed to adjust?
Solution:
C/k = First step’s capacitor power / Current transformer ratio
C/k= 1kVAr / (100/5) =0,05 is found.
