t1 = Moment of detection of the fault in protections A and B.
t2 = Tripping order of circuit breakers A and B (it may not happen at the same time).
t3 = Opening of circuit breakers A and B (it may not happen at the same time).
t4 = Spark quenching of the arcs in circuit breakers A and B.
t5 = End of safety waiting period, in order to compensate error clear up discrepancies between circuit
breakers A and B, and order reclosing of circuit breaker B.
t6 = Closure of circuit breaker B and initiation of stabilization of relay signals of synchronism relay A.
t7 = Initiation of the set time in synchronism relay A.
t8 = End of synchronism relay time delay and internal output of synchronization enable.
t9 = Reclose order of circuit breaker A.
t10 = Closure of circuit breaker A.
t11 = Resetting of synchronism relay A.
t12 = End of output enable of synchronism relay A.
