Figure 55:
Characteristic for RCADir equal to -90°
When
OpModeSel
is set to
3I03V0Cosfi
the apparent residual power component in the
direction is measured.
When
OpModeSel
is set to
3I0 and fi
the function will operate if the residual current is
larger than the setting
INDirPU
and the residual current angle is within the sector
RCADir
±
ROADir
.
The characteristic for
RCADir
= 0° and
ROADir
= 80° is shown in figure
.
