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.

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.

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.
