UMG 96RM

Harmonics

Harmonics are the integer multiple of a mains frequency.
The voltage mains frequency for the UMG 96RM 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.

in the L3 phase (example).

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.
