UMG 96RM-PN
Harmonics
Harmonics are the integer multiples of a fundamental
oscillation.
On the UMG 96RM-PN the fundamental oscillation of
the voltage must be in the range from 45 to 65 Hz. At this
fundamental oscillation the calculated harmonics relate
to the voltages and currents.
Harmonics up to 40 times the fundamental oscillation
are captured.
The harmonics for the currents are given in amps,
the harmonics for the voltages in volts.

phase L3 (example).

Total Harmonic Distortion (THD)
THD is the ratio of the effective value of the harmonics to
the effective value of the fundamental oscillation.
