4.7. Voltage measurement modes
The relay can be connected to zero-sequence voltage. The
configuration parameter "Voltage measurement mode" must be
set to "U
0
".
The available modes are:
 "U
0
"
The device is connected to zero sequence voltage.
Directional earth fault protection is available (see Figure
4.7-1 and Figure 8.8.1-1).
