Using the Harmonic
Analysis Function (optional)
Displaying the Results of Harmonic Analysis
Depending on the setting of display function of display B and C, the analyzed items will appear
on the display as follows. In the following explanation a maximum of 50 analysis orders is
assumed. In case of a maximum less than 50, computation/display will be performed up to that
order.
Display B
V
: Shows the analysis value of the voltage corresponding to the order shown on display A;
A
: Shows the analysis value of the current corresponding to the order shown on display A;
W
: Shows the analysis value of the active power corresponding to the order shown on
display A;
PF
: Shows the power factor of the fundamental (1st order);
V%
: Shows the harmonic distortion of the voltage followed by the character “t”; Two
computation methods are available; Refer to page 8-4 for details. The display range is
0.00 to 99.99 and 100.0 to 999.9%.
A%
: Shows the harmonic distortion of the current followed by the character “t”; Two
computation methods are available; Refer to page 8-4 for details. The display range is
0.00 to 99.99 and 100.0 to 999.9%.
V%
: Shows the relative harmonic content of the voltage corresponding to the order shown
on display A; The display range is 0.00 to 99.99 and 100.0 to 999.9%.
A%
: Shows the relative harmonic content of the current corresponding to the order shown on
display A; The display range is 0.00 to 99.99 and 100.0 to 999.9%.
W%
: Shows the relative harmonic content of the active power corresponding to the order
shown on display A; The display range is 0.00 to
±
99.99 and
±
100.0 to
±
999.9%.
V deg : In case the fundamental (1st order) is shown on display A
Shows the phase angle between the 1st order of the current and the 1st order of the
voltage. G (phase lag) or d (phase lead) will also be displayed.
In case the 2nd to 50th order is shown on display A
Shows the phase angle between the 1st order of the voltage and the 2nd to 50th order of
each voltage. A – (minus) will be displayed in front of the order only when the 2nd to
50th order is phase-lagged. The display range is –180.0 to 180.0 deg.
A deg : In case the fundamental (1st order) is shown on display A
Shows the same as in case of V deg.
In case the 2nd to 50th order is shown on display A
Shows the phase angle between the 1st order of the current and the 2nd to 50th order of
each current. A – (minus) will be displayed in front of the order only when the 2nd to
50th order is phase-lagged. The display range is –180.0 to 180.0 deg.
Display C
V
: Shows each rms (computed) value of the 1st to 50th harmonic component of the
voltage;
A
: Shows each rms (computed) value of the 1st to 50th harmonic component of the
current;
W
: Shows each rms (computed) value of the 1st to 50th harmonic component of the active
power;
