0: Not
Used
The voltage channel U3 can be used to measure zero sequence voltage
(U0) or the Synchrocheck voltage (SS). If neither is needed, the (default)
option "Not Used" should be active. This setting is only valid if the
"2LL+U3+U4" mode is selected.

Defines how the secondary voltage is scaled to the primary. Does not
affect how protection operates, it only affects the displayed primary
voltages. This parameter is visible when the "U3 mode U0 or SS" has been
set to the "U0" mode.

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 measured line-to-line and zero
sequence voltages.

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.
U4 Polarity
0: -
1: Invert
-
0: -
The selection of the fourth voltage measurement channel's (U4) 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.
