6.2.3 Phasors
PATH: ACTUAL VALUES Ö A1 METERING ÖØ PHASORS
• Va PHASOR: Displays a phasor representation for the magnitude and angle of Va. Va is
used as a reference for all other phasor angles. If there is no voltage present at the
PQMII voltage inputs, then Ia will be used as the reference for all other angles. Va is
also used as the reference when in Simulation Mode.
• Vb/Vc PHASOR: Displays a phasor representation for the magnitude and angle of Vb/
Vc. Both
VB and VC PHASOR values use the angle of VA PHASOR as a reference point. If
there is no voltage at the PQMII voltage inputs,
IA PHASOR is used as the reference.
These setpoints are not displayed when the PQMII is configured for the “3 Wire Delta/2
VTs”, “4 Wire Wye/2 VTs”, or “Single Phase Direct” connections.
• Ia PHASOR: A phasor representation for the magnitude and angle of Ia is displayed
here. Ia is used as a reference for all other Phasor angles only when there is no voltage
present at the PQMII voltage inputs, otherwise, Va is used as the reference.
• Ib/Ic PHASOR: A phasor representation for the magnitude and angle of Ib/Ic is
displayed here. The Ib and Ic currents use the angle of Va as a reference point. If there
is no voltage at the PQMII voltage inputs, Ia is used as the reference. These setpoints
are is not displayed when the PQMII is configured for “Single Phase Direct” connection.
