8.5. "CURRENT" FUNCTION
This function permits to display in real time the RMS value of AC/DC currents, the peak
and Thdl value (see paragraph 17.11) of the 3 phase currents, the waveform and the
harmonic spectrum of the 3 phase currents.
8.5.1. Symbols
The CURRENT position has three working modes:
 METER
 WAVE
 HARM
These modes will be described in detail in the next paragraphs.
The symbols used are described below:
Symbol
Description
I1, I2, I3
RMS value of the current of phase 1, phase 2, phase 3 respectively
IN
RMS value of the current on the neutral
Ipk1, Ipk2, Ipk3
Peak value of the current of phase 1, phase 2, phase 3 respectively
h01 h49
Harmonic 01 harmonic 49.
ThdI
Total harmonic distortion factor of the current (see paragraph 17.11).
freq
Network frequency
