An Example of Assignment of Measuring Points to the Capacitor-Bank Functions
You can connect the Capacitor bank function group to the current and voltage measuring points via inter-
faces. You make this assignment in DIGSI via Project tree → Function group connections. To connect the
interfaces, set a cross at the intersection between the row and column in the matrix.

Figure 5-16 Connecting Measuring Points to the Capacitor Bank Function Group
For the protection functions applied on the interfaces 3-phase current and 3-phase voltage, if you add these
functions to the Capacitor bank function group, these functions will automatically receive the measured
values from the correct measuring points. If you add protection functions to the function group but the neces-
sary interface is not connected to any measuring point, DIGSI 5 reports an inconsistency. Configure the meas-
uring points in DIGSI 5 using the Function group connections editor.
For the protection functions applied on the interfaces Current unbalance and 3-phase current, you have to
select the desired measuring points via a setting MP selection, which offers a list of all measuring points
connected to the specific interface. The setting MP selection is located on the setting page of the protec-
tion function.
The following figure shows an overview of the protection functions and the interface assignment in the
Capacitor bank function group.
