Figure 804: Example connection between protection and autoreclosing functions
in protection relay configuration
It is possible to create several sequences for a configuration.
Autoreclose sequences for overcurrent and non-directional earth-fault protection
applications where high speed and delayed autoreclosings are needed can be as
follows:
Example 1
The sequence is implemented by two shots which have the same reclosing time for all
protection functions, namely I>>, I> and Io>. The initiation of the shots is done by
activating the operating signals of the protection functions.
