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 cosφ 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 cosφ value is bigger than system's target cosφ value, it lights over compensation alarm. If this continues 60sec., " " lights and the alarm is turned on.

General Rules for Compensation

1 - Current transformer that is connected reactive power controller must have .../5A ratio.
2 - After current and voltage connections of the controller is madecarefully according to connection scheme, Cosφ and C/k
     values must be adjusted according to system's need.
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.

General Rules for Compensation

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 kV Ar. 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.

Installation of A Compensation System

Example: There is a system that has Cosφ=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=SxCosφ=50x0,80=40kW
Cosφ=0,80 value is reached to target Cosφ=1,00 value by using a multiplier that is taken from "Target Cosφ 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 cosφ=1,00 value. Like in this example, system's reactive power is 30kV Ar.
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 30kV Ar / 23 = 1,3kVAr is found.
Nearest value 1,5kVAr or 1kVAr is selected. If we also think %20 tolerance, we choose 1kV Ar.
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.
