Graphic illustration in the form of rotating phasors relative to the sine wave graph of a
four wire wye circuit is available by pressing the Demo button on the Phasor screen
(see page 3-19). The Demo button will be replaced by Start/Stop once phasor rotation
has been viewed. Press Start to replay animated phasor rotation. Users can choose to
Stop the phasor demo rotation at any time.
Phasor vectors are displayed using a clockwise rotation from the zero degrees
reference. Animated phasor demo for Resistive, Inductive and Capacitive loads is
available for viewing.
The following diagrams describe the positive phase rotation of voltage and current
phasors (for Resistive, Inductive and Capacitive loads) for a three phase, three wire
wye connection. An arrow head on the line indicates direction pointing toward the load.
Three phase vectors are
displayed as three lines, 120
degrees apart in a Resistive load
