ABB RELION REX640 - 3.9.4 Signals; 3.9.4.1 FLTRFRC Input signals; 3.9.5 Settings; 3.9.5.1 FLTRFRC Settings

Table 85: Special conditions
Condition Description
URES1 connected to the cal-
culated residual voltage
The function requires that all three voltage channels are con-
nected to UTVTR. Setting VT connection must be "Wye" in
that particular UTVTR.
URES2 connected to the cal-
culated residual voltage
The function requires that all three voltage channels are con-
nected to UTVTR. Setting VT connection must be "Wye" in
that particular UTVTR.
URES3 connected to the cal-
culated residual voltage
The function requires that all three voltage channels are con-
nected to UTVTR. Setting VT connection must be "Wye" in
that particular UTVTR.
