Curcuit 4-wire system with current measurement
"PQ Values for"
o
Calculation of the PQ-values for
Phase-N
or
Phase-Phase
. The voltage's harmonics and THD-value, as well
as the flicker values, are only calculated for this system.
o
The respective mean, min and max voltage values, the curve plots and fault records can be calculated for
Phase-N
and
Phase-Phase
in parallel. This is performed in accordance with the settings on the page
.
o
For a
Phase-Phase
system, no line power values are calculated.
"U calculate RMS value PN and PP“
o
Calculation of the voltage RMS mean values in parallel for
Phase-N
and
Phase-Phase
.
