III.11 Graphic Phasor Diagram
Press this button to display the phasor diagram.
The voltages and currents will be displayed in phasor format (magnitude, angle).
V1 will be referred as reference. The angle of V1 is always 0. The phase angles
of V2, V3, I1, I2, and I3 will be displayed with respect to V1. V1, V2, V3, I1, I2, I3,
V12, V23, and V31 will be displayed in vector form graphically.
V1, V2, V3:
Phase voltages in phasor format with respect to V1
I1, I2, I3:
Line currents in phasor format with respect to V1.
IVn:
Calculated voltage and current of neutral with respect to ground.
V12, V23, V31:
Line voltage in phasor format with respect to V1.
Ave:
Average of line voltages V12, V23, and V31 and line current I1, I2, and I3
dV%:
Historical maximum % value of
(Max (V1, V2, V3) – Min (V1, V2, V3)) / Min (V1, V2, V3) * 100%
VUR:
Voltage Unbalance Ratio
d02:
The first number is Zero Sequence Unbalance Ratio in % (d0) of voltage.
The second number is the Negative Sequence Unbalance Ratio in % (d2) of
voltage. When VUR is displayed before d02, d02 represents the Zero and
Negative Sequence Unbalance Ratios for voltage.
REF:
nominal voltage for transient detection reference
Sd%:
threshold in % for transient detection with respect to nominal voltage (REF).
