Generator potential transformer secondary
[1] 50 to 125 V; [4] 50 to 480 V
The potential transformer secondary voltage is set here in V. This parameter is util-
ized to calculate the system voltage in the display. For voltages measured without a
potential transformer, secondary and primary voltage must be configured the same.

The potential transformer primary voltage is set here in kV. This entry is used to
show the system voltage in the display.
Example:
If a voltage of 400 V is measured without a potential transformer, the secondary transformer voltage
must be configured to
400V
and the primary transformer voltage must be configured to
00.400V
