6.5.4 Harmonic
From the „Harmonics“ tab page, all of the current and voltage harmonics (2nd
to 50th) can be displayed online. The measurement data is calculated by the
measuring device in accordance with IEC61000-4-30 Class A and transferred to
the PC.
There are three bar charts available::
Voltage harmonics conductor-earth
Voltage harmonics conductor-conductor
Current harmonics
As the EN50160 only specifies limits for harmonics up to the 25th ordinal, the
compatibility level of IEC61000-2-2 has been stored for the 26th to the 50th har-
monics in the basic settings.Compatibility levels in accordance with EN50160 &
IEC61000-2-2 are shown as green limit value bars.
If a harmonic is selected with the mouse pointer, this measurement value is
displayed in the field on the top right.
