Steps Connected: Defines the number of steps
operational. Depending on PF system banks, this
parameter is set.
• Default Mode: 0: Auto and 1: Manual. This parameter
defines the mode during Power up. (Default is 0: Auto)
• Compensation kVAr: 0:Instantaneous & 1:Mean.
Defines the method for kVAr compensation. If it should be
instant at which the compensation is made or it is mean
of kVAr that is required from previous
present compensation.
• Capacitor Bank Voltage: Capacitor bank voltage line to
line value is defined here. i.e. it defines the Voltage value
at the defined kVAr.
• Correction Time: Defined in seconds. This is the Time
between two consecutive kVAr compensations.
• Discharge Time: Time defined here is the time for
discharge of the capacitors to a level, so that they can be
turned ON again.
• Step Response Time: Defines the time after which the
kVAr of any step should be measured when the step turns kVAr of any step should be measured when the step turns
on .
•Interleaving Delay: Interleaving delay is settable.
• Fix-Bank Setting: Defines the banks that are to be
declared as fixed. These banks even in spite of
overcompensation cannot be turned OFF. The banks can
only be turned OFF under fault conditions. (if settings in
fault are defined).
•C/E Series Bank kVAr: The kVAr defined here is the
capacitor bank kVAr of the smallest bank i.e. this
capacitor step kVAr value is defined by digit '1' in C
series, E series or Binary. Screen appears only on C or E.
• Ext Fix Bank kVAr: The kVAr value defined here is any
fix capacitor bank kVAr which is connected externally to
the APFC System & has not been included in internal
defined Bank Step configuration of the APFC system.
• Correction Type: APFC 06 can have bank configurations
that are defined by four various methods. 1=Unequal,
2=C Series, 3=E Series.
Un-equal is used with banks not having definite ratio.
C series is predefined Control Series. The standard
ratios are preloaded in APFC 06 that can be selected here.
E series is User defined Control Series. The bank ratios
that are not defined in C series can be defined here.
Digits can be 1,2,-- 9,
