Indicates whether or not phase-to-earth voltages are available. Also
indicates whether P-E voltages are measured from the voltage channels
directly or if they are calculated from line-to-line and line-to-neutral
voltages.
VT primary

The primary nominal voltage of the connected U0 VT. This setting is
visible for all modes except "3LN".
U3 Res/SS VT
secondary
0.2…120 V
0.1V
100.0V
The secondary nominal voltage of the connected U0 VT. This setting is
visible for all modes except "3LN".
U1 Polarity
0: -
1: Invert
-
0: -
The selection of the first voltage measurement channel's (U1) polarity
(direction). The default setting is for the positive voltage to flow from
connector 1 to connector 2, with the secondary voltage's starpoint
pointing towards the line.
U2 Polarity
0: -
1: Invert
-
0: -
The selection of the second voltage measurement channel's (U2) polarity
(direction). The default setting is for the positive voltage to flow from
connector 1 to connector 2, with the secondary voltage's starpoint
pointing towards the line.
U3 Polarity
0:-
1:Invert
-
0:-
The selection of the third voltage measurement channel's (U3) polarity
(direction). The default setting is for the positive voltage to flow from
connector 1 to connector 2, with the secondary voltage's starpoint
pointing towards the line.
VT scaling
factor P/S

A relay feedback value; the calculated scaling factor that is the ratio
between the primary voltage and the secondary voltage.
VT scaling
factor p.u. Pri

A relay feedback value; the scaling factor for the primary voltage's per-
unit value.
VT scaling
