008 Compensated
Volt. Secondary
XXX.X Volts
Volts View NA NA NA NA NA
•This is the calculated voltage at the center of regulation, referred to the secondary.
•This is based on the resistive compensation setting (FC 4 or FC 54), reactive compensation
setting (FC 5 or FC 55), and the load current.
•This is the voltage that the regulator is regulating during either forward or reverse
power flow.
•During reverse power operation, the control requires source voltage from a differential or
source potential transformer or from the source voltage calculation (see FC 39) to obtain
this parameter. Lack of this voltage will result in the parameter displaying dashes.
009 Load Current
Primary
XXX.X Amps
Amps View NA NA NA NA NA
•This is the fundamental RMS current flowing in the primary circuit.
•This parameter is scaled according to the CT primary rating which is entered at FC 45.
•During reverse power operation, the control requires source voltage from a differential or
source potential transformer or from the source voltage calculation (see FC 39) to obtain
this parameter. Lack of this voltage will result in the parameter displaying dashes.
010 Load Voltage
Primary kV
XX.XX kVolts
KV View NA NA NA NA NA
•This is the fundamental RMS voltage, referred to the primary, which appears at the output
(load) terminals of the regulator.
•During reverse power operation, the control requires source voltage from a differential or
source potential transformer or from the source voltage calculation (see FC 39) to obtain
this parameter. Lack of this voltage will result in the parameter displaying dashes.
011 Source Voltage
Primary kV
XX.XX kVolts
KV View NA NA NA NA NA
•This is the fundamental RMS voltage, referred to the primary, which appears at the input
(source) terminals of the regulator.
•Since ratio correction is performed by the firmware, this parameter is scaled according to
the inputs at FC 43 (System Line Voltage) and FC 44 (Internal PT ratio).
•During forward power operation, the control requires source voltage from a differential or
source potential transformer or from the source voltage calculation (see FC 39) to obtain
this parameter. Lack of this voltage will result in the parameter displaying dashes.
012 Present Tap
Position
-XX
Tap View 3 NA NA -16 16
•This is the present position of the tap-changer.
•The tap position indication is synchronized at the neutral position, as indicated by the
neutral light circuit. Tap positions are displayed from -16 to 16, corresponding to 16
Lower (regulator bucking) to 16 Raise (regulator boosting), respectively.
•See Section 6: Control Features: Tap position indication (TPI).
•See Percent Regulation, FC 112.
