•
Steps Connected: Defines the number of operational
steps . Depending on the capacitor bank steps of the
APFC system, this parameter is set. Maximum 16 banks
can be connected.
•
Capacitor Bank Voltage: Capacitor bank voltage line-to-
line value is defined here. i.e. it defines the Voltage value
at the defined kVAr.
•
Smallest kVAr safety Fact: This factor defines the no
action zone prohibiting the capacitor bank On/Off
operation to avoid hunting.
•
Correction Time: Defined in cycles. This is the Time
between two consecutive kVAr compensations i.e time
between change in load kVAr demand & subsequent
switching of capacitor bank steps. This can be set within 1
to 240 line Cycles.
•
Discharge Time: Time defined here is the time for
discharge of the capacitors to a level, so that they can be
turned ON again. This can be set within the range of 1 sec
to 300 sec.
•
IntrLeaving Dely: This is the switching delay between
two bank execution. User can set it as instantaneous or 1
Sec as a option.
•
Fixed bank setting: In this, any bank(no of banks
depends upon the steps connected) can be set as fixed
bank.
•
Unequal Bank kVAr [1….16]: The capacitor bank step
configuration values are to be set here .These parameters
are to be defined for each bank kVAr (at defined
Capacitor Bank Voltage). TPF-56 has an in-built intelligent
algorithm to select the best possible combination to suit
the exact kVAr requirement for compensation.
