EXAMPLE
The selected application template DIS overhead line, grounded systems, 1 1/2 circuit-breaker layout
comprises 3 function groups:
•
Protection function group Line 1
•
Circuit-breaker function group QA 1
•
Circuit-breaker function group QA 2
The following figure shows the embedding of functions via function groups.

Figure 2-1 Embedding the Functions via Function Groups
Depending on the type of device, there are different types of function groups:
•
Protection function groups
•
Circuit-breaker function groups
Protection function groups bundle functions that are assigned to one protected object – for example, to the
line. Depending on the device type and nature of the protected object, there are different types of protection
function groups (line, voltage/current 3-phase, transformer, motor, generator, etc.).
Circuit-breaker function groups bundle functions assigned to the local switches – for example, circuit breakers
and disconnectors (such as processing of tripping, circuit-breaker failure protection, automatic reclosing).
The number and type of function groups differ in the respective application templates, depending on the type
of the device and application. You can add, copy, or even delete function groups for a specific application. You
can also adapt the functional scope within a function group according to the use case. Detailed information on
this can be found in the DIGSI 5 Online help.
