7.7.3 HARMONICS CHECK
Group of parameters number [191]
Parameters for enabling and configuring the check of harmonic currents and voltages. The long-term
increase in harmonic distortion can be caused by rapid deterioration of connected distribution network, by
damage of the inverter or incorrect parameter adjustment.

Turning on the check of high harmonic
currents [223] (page 19) and selection of
individual harmonics. The test is performed
only when the inverter is running.

When this choice is active, the sum of harmonic currents is calculated. When this sum exceeds
the value of Max. harm. I [825] (page 75) for more than Filter harm. fault [845] (page 76), the
fault E43-I harmonics (page 33) is generated.
