L1 CURRENT HARMONICS
Item Function
Data about harmonic indicated by cursor:
A-h05: harmonic number
%: level of harmonics with fundamental RMS value (%f) or (total) RMS value (%r) as reference
A: RMS current of harmonic
1
+178°: phase shift with respect to fundamental (order 1)
max – min: maximum and minimum levels of harmonic. Reset when harmonic number is changed or
THD: total harmonic distortion
Ad: RMS distortion current
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 current harmonics of phases 2 and 3, respectively. The screen is identical to the one
displayed for filter L1.
There is no phase shift or distortion value for the neutral channel.
