General Information: 1.9 ORDER CODE
].
5.1 Actual values: LINE VOLTAGES
Line Voltages
Vab= 0.00 V
Vbc= 0.00 V
Vca= 0.00 V
RMS value of Line Voltages.
5.2 Actual values: PHASE VOLTAGES
Phase Voltages
Van= 0.00 V
Vbn= 0.00 V
Vcn= 0.00 V
RMS value of Phase Voltages.
[6.2 Setpoints: SYSTEM SETUP]
If VT Connection = Wye
5.3 Actual values: PHASE SEQUENCE
Phase Sequence
None
RANGE: NONE; ABC; ACB
NONE: when the VFR is not capable of detecting the Phase Sequence.
For instance, in case of phase loss or insufficient voltage.
ABC: Direct sequence
ACB: Inverse sequence
5.4 Actual values: VOLTAGE AVG,UNB,THD
Voltage Avg,Unb,THD
Voltage Avg= 0.00 V
Voltage Unb= 0.0 %
THD= 0.0%
(*)
-
Average of the 3 RMS values of line voltages
Vavg=(|VAB| + |VBC| + |VCA|)/3.
-
Unbalance line voltages percentage (maximum of the three unbalance
values).
-
Voltage THD value (Voltage Total Harmonic Distortion).
