Cooperation of the Automatic Reclosing Function and Protection Functions

6.45.3
The Automatic reclosing function (AREC) can be influenced by the protection functions in the following way:
•
The AREC is started through pickup indications and operate indications by the selected protection func-
tions or protection stages. The start is independent of the set operating mode for the AREC.
•
Individual protection functions or protection stages can be configured so that their operate indication
blocks the AREC. If such a blocking exists, the AREC cannot be started. If the AREC is already started, the
blocking will lead to the cancellation of the AREC.
The automatic reclosing device can thus have an influence on the effects of the protection functions. The
following influence possibilities exist:
•
The AREC provides signals that can be used by protection functions for the blocking or release of special
stages or zones. An example is the release of overreaching zones with distance protection.
