NOTE
4.5 Vector Display of Harmonics
The harmonic vector display shows the voltage, current, and phase angle for
each harmonic, making clear the phase relationship between voltage and
current. The numeric values of the displayed harmonics also appear.
For details on wiring mode and vector display, see Appendix.
･ It is only possible to display the voltage and current for a single system on
the screen. Again, only one harmonic can be selected for display. Therefore,
for a single phase system two lines (voltage and current) appear, and for a
three-phase four-wire system, six lines (voltage
× 3, current × 3) are
displayed.
･ By setting the hold state, and switching the screen, it is possible to read
other analysis data for the same time instant.
･
The distortion is not displayed.
･
The voltage/current phase angle indicates the phase angle taking the phase
angle of the fundamental from the PLL source as 0
。
.
･
The power phase difference indicates the phase difference of the current with
respect to the voltage on the same channel for each harmonic.
･ This reflects the harmonic selected on the harmonic graph display.
･ When sorting is enabled, the same degree may not be displayed.
