GOAL :

repair after transient fault

80 % to 90 % of faults to the electrical network are transient

Cycle temporisation :

time that is long enough to allow the fault to be cleared

Autorecloser : what for?

• Add / Configure a AR (1)1) Autorecloser can be added at Bay Level .

Built-in function :Autorecloser type 1

2) Autorecloser attributes : General Tab

Functioning mode 1P :1P, 1P-3P, 1P-3P-3P, 1P-3P-3P-3P (CB-1ph)

Functioning mode 3P :

3P, 3P-3P, 3P-3P-3P, 3P-3P-3P-3P (CB-3ph)

Unlocking way :not used / reinitialisation / manual close / both

Fast 3P reclose enable :bypass Synchrocheck during 1st cycle 3P

• Add / Configure a AR (2)

4) Autorecloser attributes : Cycles and delays Tab

Cycles time

Other timers :

• inhibition

• not used => starts reclaimml timer if alllocking conditions disappear and CB closed(cf. C264_FT). If CB not closed at the end oftimer, AR is locked again.

• manual close => starts reclaimmc timer ifbreaker is closed manually and AR isinhibited during this delay (cf. C264_FT). IfCB not closed at the end of timer, AR is

locked again.

Reclaim timer

3) Unlocking way :• not used = when locking conditions disappear and CB closed • manual close = when operator is closing manually CB • lock/reinit = when LOCK/REINIT SPS or SPC is set

• AR Sons & Relations (1)1) Autorecloser basic configuration :

MPS AR FAULTYGives reason of AR

Failure

MPS AR STATEGives current step of ARExecution

SPC Force Trip 3Pwhen 1st cycle 1P, force

IED to next trip in 3P

On/off DPSAR is active or not => initial status to be “Set”

Trip 3 phases SPSAcquired SPS giving 3ph. trip status

Hardwired SPS is strongly advised, butcan come from IED or PSL.

Relation with CB

• AR Sons & Relations (2)2) Autorecloser enhanced configuration :

=> Possible sonsSPS AR BLOCKINGWhen “SET” => AR does not close at end of current cycle hardwired or produced by PSL then wait for 1st cycle

SPS LOCK/REINITSPS giving order to unlock. If active, AR is unlocked.Cannot be configured if SPC LOCK/REINIT exists.

3 Trip phases SPS

Acquired SPS giving Trip status per phase Hardwired SPS is strongly advised

SPC LOCK/REINITSPC giving order to unlock or reinit AR.Cannot be configured if SPS LOCK/REINIT exists.
