6.2. POSITION "CURRENT"
This function permits to display in real time the RMS value of AC/DC currents, the peak
and Thdl value (see paragraph 16.2) of the 3 phase currents, the waveform and the
harmonic spectrum of the 3 phase currents.
6.2.1. 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
16.2
).
freq Network frequency
