4.2.4.2 PHASE-TO-PHASE VOLTAGE DISPLAY SCREEN (L1)
Item Function
1
Harmonic selection cursor; change values with the cursor using the ◄ and ►buttons
The horizontal axis indicates the orders of the harmonics (odd marking). Display of the level of the harmonics as a percentage of the
fundamental (order 1)
2
- DC: DC component
- 1 to 25: harmonics of order 1 to 25; when the cursor exceeds order 25, order 26 to 50 appears
-
: indicator of the presence of non-zero harmonics of order higher than 25
- Uh 03: harmonic number
%: ratio of the harmonic to the fundamental
V: RMS voltage of the harmonic in question
3
+000°: phase shift with respect to the fundamental (order 1)
max – min: maximum and minimum levels of the harmonic in question (reset when the harmonic number is changed or the
is pressed)
THD: total harmonic distortion
NOTE: Filters L2 and L3 display the harmonics of the phase-to-neutral voltage for phases 2 and 3, respectively. The screen is
identical to the one displayed for filter L1.
