• AR BREAKER SEQUENCE : This setting selects the breakers reclose sequence: Select “1” for reclose breaker 1 only,
“2” for reclose breaker 2 only, “1&2” for reclose both breakers simultaneously, “1-2” for reclose breakers sequentially;
Breaker 1 first, and “2-1” for reclose breakers sequentially; Breaker 2 first.
• AR TRANSFER TIME : The transfer time is used only for breaker closing sequence 1-2 or 2-1, when the two breakers
are reclosed sequentially. The transfer timer is initiated by a close signal to the first breaker. The transfer timer trans-
fers the reclose signal from the breaker selected to close first to the second breaker. The time delay setting is based on
the maximum time interval between the autoreclose signal and the protection trip contact closure assuming a perma-
nent fault (unsuccessful reclose). Therefore, the minimum setting is equal to the maximum breaker closing time plus
the maximum line protection operating time plus a suitable margin. This setting will prevent the autoreclose scheme
from transferring the close signal to the second breaker unless a successful reclose of the first breaker occurs.
