Synchronism function (25) associated to manual closure (52)
If “ 52 permission of closure” is associated with “Permission of closure” of synchronism function, could
be occur:
1. If permissions LLLB, DLLB, LLDB y DLDB of 25 function are all prohibited, the closure of the circuit
breaker
does not occur. In spite of “close breaker” command being execute by communication or
pressing the key in the relay, circuit breaker never will close
2. If LLLB, DLDB, DLLB, y LLDB permissions of 25 function are enable it can be distinguished some
possibilities:.
a) If line, bar or both of them are dead it will always produced the manual closure of the circuit
breaker
because “52 permission of closure” only depends on corresponding permission
adjustment, and it is not necessary synchronism to get the circuit breaker closure.
b) If both, line and bar, are alive it will be necessary to get the manual closure of the circuit
breaker, not only LLLB permission to be enable either to check synchronism. If LLLB
permission is enable but synchronism conditions do not verify, after pressing CLOSE
BREAKER command, circuit breaker closure does not occur and vice versa.
