Deif GPC-3 Designers Reference Handbook

Below is an example with 230/400 V AC, which can be connected directly to the GPC's terminals without the
use of a voltage transformer. If a voltage transformer is necessary, the nominal values of the transformer
should be used instead.
Setting Adjustment Description Adjust to
value
6004 G nom. voltage Phase-phase voltage of the generator 400 V AC
6041 G transformer Primary voltage of the G voltage transformer (if installed) 400 V AC
6042 G transformer Secondary voltage of the G voltage transformer (if installed) 400 V AC
6051 BB transformer set 1 Primary voltage of the BB voltage transformer (if installed) 400 V AC
6052 BB transformer set 1 Secondary voltage of the BB voltage transformer (if instal-
led)
400 V AC
6053 BB nom. voltage set 1 Phase-phase voltage of the busbar 400 V AC
The GPC has two sets of BB transformer settings, which can be enabled individually in this
measurement system.
3.7.2 Single phase system
The single phase system consists of one phase and the neutral.
The table below contains the parameters to make the system ready for single phase measuring.
Below is an example with 230 V AC, which can be connected directly to the GPC's terminals without the use
of a voltage transformer. If a voltage transformer is necessary, the nominal values of the transformer should
be used instead.
Setting Adjustment Description Adjust to
value
6004 G nom. voltage Phase-neutral voltage of the generator 230 V AC
6041 G transformer Primary voltage of the G voltage transformer (if installed) 230 V AC
6042 G transformer Secondary voltage of the G voltage transformer (if installed) 230 V AC
6051 BB transformer set 1 Primary voltage of the BB voltage transformer (if installed) 230 V AC
6052 BB transformer set 1 Secondary voltage of the BB voltage transformer (if instal-
led)
230 V AC
6053 BB nom. voltage set 1 Phase-neutral voltage of the busbar 230 V AC
The voltage alarms refer to U
NOM
(230 V AC).
The GPC has two sets of BB transformer settings, which can be enabled individually in this
measurement system.
3.7.3 Split phase system
This is a special application where two phases and neutral are connected to the GPC. The GPC shows pha-
ses L1 and L3 in the display. The phase angle between L1 and L3 is 180 degrees. Split phase is possible
between L1-L2 or L1-L3.
