Figure 21 Positive Phase Sequence Rotation Using ± 180˚
For example, using 0-360 Lag (0, 120, 240) setting an angle of 30
°
between the two outputs
would look like:
The reference output is 0
°
and the second output is rotated 30
°
clockwise. In other words, the
angle is lagging the referenced source by 30
°
.
Conversely, if the angle decreases in the counterclockwise direction from 359.9
°
toward 0.0
°
, for
a setting angle of 300.0
°
, the second output would look like:
The reference output is 0
°
and the second output is rotated to 60
°
in the counterclockwise
direction. In other words, the second output lags the reference output by 300
°
or leads it by 60
°
.
The user may default to phase angles to
±
180
°
with the

(negative) angles lagging and the
