UMG 96RM-EL

Harmonics

Harmonics are the integer multiple of a mains frequency.
The voltage mains frequency for the UMG 96RM-
EL must be in the range between 45 and 65 Hz. The
calculated voltage and current harmonics refer to this
mains frequency.
Harmonics up to 40x the mains frequency are recorded.

The harmonics for currents are given in amperes
and the harmonics for voltages are given in volts.

Fig. Display of the 15th harmonic of the current
in the L3 phase (example).

Harmonics are not displayed in the factory
default setting.

Total Harmonic Distortion (THD)

THD is the ratio of the root mean square value of
harmonics to the root mean square value of the mains
frequency.
