(Enter Capacitor Bank Kvar) Only If MANUAL
(Capacitor Bank 1 to 12) Is Selected
Working
Control Mode:
1) Kvar Mode :
Ÿ
When this mode is selected, capacitor bank switching step is not fixed
and the program automatically selct the most appropriate steps to switch
capacitor bank "ON' or "OFF" in order to achieve target PF by shortest
reaction time with minimum number of steps.
2) Intel Mode :
Ÿ
When this mode is selected the capacitor steps are controlled by increment
of lowest KVAr value of capacitor bank to higher KVAr value of capacitor bank
combinations using binary steps to achieve required KVAr value and target PF.
3) MANUAL Mode :
Ÿ
When this mode is selected the capacitor steps are controlled manually by the
UP ( ) and DOWN ( ) KEY.
Capacitor Bank Sensing :
1) MANUAL :
Ÿ
If customer select manual Capacitor Bank Sensing method then it will be
mandatory to enter capacitor bank KVAr value for each step.
Ÿ
No need for external CT.
[
2) CAPACITOR CT :
Ÿ
If customer select Capacitor CT Capacitor Bank Sensing method than capacitor
bank automatically sense by capacitor CT.
Ÿ
The use of capacitor CT is mandatory.
