ABB Relion REC670 - Apparatus Control APC; Application

UnsucClByCBCheck , Unsuccessful closing by CB check
The normal setting is NoCBCheck . The “auto-reclosing unsuccessful” event is then decided by
a new trip within the reclaim time after the last reclosing shot. If one wants to get the
UNSUCCL (Unsuccessful closing) signal in the case the CB does not respond to the closing
command, CLOSECB, one can set UnsucClByCBCheck = CB Check and set tUnsucCl for instance
to 1.0 s.
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 synchrocheck at the first CB. Typical setting is
tWaitForMaster=2sec .
AutoCont and tAutoContWait , Automatic continuation to the next shot if
the CB is not closed within the set time
The normal setting is AutoCont = Off . The tAutoContWait is the length of time SMBRREC waits
to see if the breaker is closed when AutoCont is set to On . Normally, the setting can be
tAutoContWait = 2 sec .

The apparatus control is a function for control and supervising of circuit breakers,
disconnectors, and earthing switches within a bay. Permission to operate is given after
evaluation of conditions from other functions such as interlocking, synchrocheck, operator
place selection and external or internal blockings.

commands. Commands to an apparatus can be initiated from the Control Centre (CC), the
station HMI or the local HMI on the IED front.
