Figure 375: 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 ground-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 reclose time for all
protection functions, namely 50P-1, 51P and 51N/G. The initiation of the shots is done by
activating the trip signals of the protection functions.
