8.3.9 PHASORS
The 469PC software can be used to view the phasor diagram of three phase currents and voltages. The pha-
sors are for:
• Phase Voltages A, B, and C
• Phase Currents A, B, and C
1. With 469PC running and the communications established, open the Metering Data window by selecting
the
Actual > Metering Data
menu item then clicking the
Phasors
tab. The phasor diagram and the values
of voltage phasors, and current phasors are displayed.
Longer arrows are the voltage phasors, shorter arrows are the current phasors.
2. Va and Ia are the references (i.e. zero degree phase). The lagging angle is clockwise.
