3L PHASE-TO-NEUTRAL VOLTAGE HARMONICS
Item Function
Data about harmonic indicated by cursor:
V-h03: harmonic number
1
%: level of harmonics with fundamental RMS value as reference (%f) or (total) RMS value as reference (%r).
V: RMS voltage of harmonic
+000°: phase shift with respect to fundamental (order 1).
2
Harmonic selection cursor; change values with the cursor using the ◄ and ►buttons
Horizontal axis indicates orders of harmonics.
3
Level of harmonic is given as a percentage with respect to fundamental or total RMS value.
DC: DC component. 1 to 25: harmonics of order 1 to 25. When cursor exceeds order 25, order 26 to 50 appears.
Display in expert mode -.+ (on the right-hand side) is available for 3-phase hookups by pressing the ▲ and ▼ buttons.
