7.8.2.3.1 Waveforms
The filter current waveforms for all phases for the unit selected with the ‘Select unit’
option. The graph layout is similar to the one of the voltages (Figure 60). All waveforms
are synchronized with the rising edge zero crossing of the voltage V (L1-N) (4-W mode)
or V (L1-L2) (3-W mode).
7.8.2.3.2 Spectrum
The filter current spectrum for all phases (3-W mode) and the neutral current spectrum
(4-W mode) in chart format for the unit selected with the ‘Select unit’ option. The chart
layout is similar to the one of the voltages (Figure 61) but the values are expressed in
absolute terms.
7.8.2.3.3 Harmonic table
The filter current spectrum for all phases (3-W mode) and the neutral current spectrum
(4-W mode) in table format for the unit selected with the ‘Select unit’ option. The table
layout is similar to the one of the voltages (Figure 46) but only absolute current values
are shown.
7.8.2.4 Total filter currents
Refer to Table 39 for an explanation of the parameters.
PQF Irms in table format for the complete filter system.
7.8.2.4.1 Waveforms
The filter current waveforms for all phases for the complete filter system. The graph
layout is similar to the one of the voltages (Figure 60). All waveforms are synchronized
with the rising edge zero crossing of the voltage V (L1-N) (4-W mode) or V (L1-L2) (3-W
mode).
7.8.2.4.2 Spectrum
The filter current spectrum for all phases (3-W mode) and the neutral current spectrum
(4-W mode) in chart format for the complete filter system. The chart layout is similar to
the one of the voltages (Figure 61) but the values are expressed in absolute terms.
