L1 PHASE-TO-PHASE VOLTAGE HARMONICS
Item Function
Data about harmonic indicated by cursor:
U-h03: harmonic number
%: level of harmonics with fundamental RMS value (%f) or (total) RMS value (%r) as reference
V: RMS voltage of harmonic
1
+000°: phase shift with respect to fundamental (order 1)
max – min: maximum and minimum levels of harmonic. Reset when harmonic number is changed or by pressing
THD: total harmonic distortion
Ud: phase-to-phase RMS distortion voltage
2 Harmonic selection cursor; change values with the cursor using the ◄ and ► buttons
Horizontal axis indicates orders of harmonics.
Level of harmonic is given as a percentage with respect to the fundamental or to the total RMS value.
3
Range DC: DC component
1 to 25: harmonics of order 1 to 25. When the cursor exceeds order 25, order 26 to 50 appears
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.
