7.8.2.1.1
Global values
Vrms, V1 and THDV in table format.
7.8.2.1.2
Waveforms
The network voltage waveforms for all phases (
). 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).

example)
7.8.2.1.3
Spectrum
The network voltage spectrum for all phases in chart format
). The spectral
components up to the 49
th
order are expressed as a % of the fundamental component
with absolute values also shown in the top right corner. The two buttons with “+” and “-
“ mark help changing the voltage level resolution (i.e. Y-axis value in the chart).
