Figure 2-7 Detail Configuration of the Interface Between the Protection Function Group and the Circuit-
Breaker Function Group(s)
In the detail configuration of the interface, you define:
•
Which operate indications of the protection functions go into the generation of the trip command
•
Which protection functions start the automatic reclosing function
•
Which protection functions block the automatic reclosing function
•
Which protection functions start the Circuit-breaker failure protection function
Functions (FN), Tripping Stages/Function Blocks (FB)
As already illustrated in Figure 2-1 , functions are assigned to the protected objects or other primary objects via
function groups.
Functions can be further subdivided. For example, protection functions often consist of multiple protection
stages (for example, the Overcurrent-protection function). Other functions can contain one or more function
blocks.
Each stage, each function block, and each function (without stages/function blocks) can be individually
switched into specific operating modes (for example, switch on/off). This is termed function control and is
explained in chapter
2.3 Function Control .
To adjust the functionality to the specific application, functions, tripping stages, and function blocks can be
added, copied, and deleted (see chapter
2.2 Adjustment of Application Templates/Functional Scope ).
