Application and Setting Notes for General Settings
For the automatic reclosing function, there are 3 functions available in the function library. In each circuit-
breaker function group, a function from the automatic reclosing function can be used.
Configure one of the 3 following function specifications:
•
Cyclic Automatic reclosing function
•
Automatic reclosing function with adaptive dead time (ADT)
•
Operation with External Automatic Reclosing Function
Starting the Automatic Reclosing Function
The configuration of the interaction between internal protection functions and the automatic reclosing func-
tion can be set separately for each protection function. The configuration occurs in a matrix view in DIGSI. The
Automatic reclosing function also has the corresponding binary inputs and binary outputs through which the
external protection devices can be connected to the internal Automatic reclosing function.
Configure the starting and blocking condition for the automatic reclosing function at the position shown in
Figure 7-55 in DIGSI (for example, a protection function group Line is shown here) or route the corresponding
binary inputs.
