AR SYS CHECKS
System Checks Sub Heading
CB SC all
This setting determines whether a system check (e.g. live bus / dead line etc) is required for any auto-reclose of CB. If Enabled, system check
is required for some or all reclosures. If Disabled, system check is not required for any reclosures.
CB1L SC all
This setting determines whether a system check (e.g. live bus / dead line etc) is required for any auto-reclose of CB1 as leader. If Enabled,
system check is required for some or all reclosures. If Disabled, system check is not required for any reclosures.
CB SC Shot 1
This setting determines whether a system check (e.g. live bus / dead line etc) is required for the first shot reclosure of CB. If Enabled, system
check is required for the first shot reclosure. If Disabled, system check is not required for the first shot reclosure.
CB1L SC Shot 1
This setting determines whether a system check (e.g. live bus / dead line etc) is required for the first shot reclosure of CB1 as leader. If
Enabled, system check is required for the first shot reclosure. If Disabled, system check is not required for the first shot reclosure.
CB SC ClsNoDly
If CB SC ClsNoDly is Enabled, CB can reclose as leader as soon as the synchro check conditions are satisfied, without waiting for the dead
time to elapse.
This option is sometimes required for the second line end to reclose onto a line with delayed auto-reclosing (typical cycle: first line end
recloses after the dead time with
live bus & dead line, then the second line end recloses immediately with live bus & live line in synchronism).
CB1L SC ClsNoDly
If CB1L SC ClsNoDly is Enabled, CB1 can reclose as leader as soon as the synchro check conditions are satisfied, without waiting for the dead
time to elapse.
This option is sometimes required for the second line end to reclose onto a line with delayed auto-reclosing (typical cycle: first line end
recloses after the dead time with
live bus & dead line, then the second line end recloses immediately with live bus & live line in synchronism).
CB SC CS1
This setting enables CB to auto-reclose as leader when the system satisfies all the System Check Synchronism Stage 1 criteria as defined
under CB CS1 Status settings in the SYSTEM CHECKS column.
