Touch the icon “ ”to display the parameters of
harmonic analysis. The display shows the screen on
the right (relative to a Single phase plant.
The display shows the histogram graphic of the
percentage amplitude relative to the fundamental and
the voltage harmonic V1N (Single phase) or VL1-L2
(Three phase balanced) and the fundamental and the
current harmonics from 1
th
up to 25
th
order. A blue
frame immediately identifies the harmonic of higher
amplitude (except for the fundamental). The display
shows the numeric value of the harmonics amplitudes
(identified by the “hxx” symbol) and the THD% (see §
12.13) appear in the right side of the display.
Use the arrow keys “” or “” or touch the
correspondent icon on the display to decrease or
increase the order of the harmonics
Press the SAVE button or touch the icon to save
