1BPROTECTION FUNCTIONS
PROTECTION, CONTROL AND METERING FUNCTIONS
The recloser’s final status when it has executed all of the pre-programmed
reclose attempts but the breaker remains tripped, given that it is a permanent
fault. Exit from this status can only be achieved by closing the breaker
manually.
Time for first, second, third and fourth reclose.
It is the waiting time after the breaker’s trip until the recloser gives the close
order in each of the reclosing phases.
Reclaim time after manual reclose.
This is the time after the manual reclose of the breaker where if a protection
trip happens the recloser goes to definitive trip status instead of to surveillance
status.
Reclaim time after automatic reclose.
This is the time after the automatic reclose of the breaker where if a protection
trip happens the recloser continues the cycle instead of going to surveillance
status.
Close conditions time (optional use).
It is the time margin, after a protection trip, during which the close conditions
must be fulfilled to be able to continue the cycle.
