Priority and time tWaitForMaster
In single CB applications, one sets
Priority
=
None
. At sequential reclosing the function
of the first CB, e.g. near the busbar, is set
Priority
=
High
and for the second CB
Priority
=
Low
. The maximum waiting time,
tWaitForMaster
of the second CB is set longer than the
“auto-reclosing open time” and a margin for synchronism check at the first CB. Typical
setting is
tWaitForMaster=2sec
at the energizing side and perhaps 15 or 300 seconds at the
synchrocheck , synchronizing side.
AutoCont and tAutoContWait, Automatic continuation to the next shot if the
CB is not closed within the set time
The normal setting is
AutoCont
=
Disabled
. The
tAutoContWait
is the length of time
SMBRREC (79) waits to see if the breaker is closed when
AutoCont
is set to
Enabled
.
Normally, the setting can be
tAutoContWait = 2 sec
.

Application
The apparatus control is a function for control and supervising of circuit breakers,
disconnectors, and grounding switches within a bay. Permission to operate is given after
evaluation of conditions from other functions such as interlocking, synchronism check,
operator place selection and external or internal blockings.
gives an overview from what places the apparatus control function receive
commands. Commands to an apparatus can be initiated from the Control Centre (CC), the
station HMI or the local HMI on the IED front.
