14.3.7.5 Operation principle
M13487-4 v5
The Circuit breaker function (SXCBR) is used by other functions such as for example, switch
controller, protection functions, autorecloser function or an IEC 61850 client residing in another
IED or the operator place. This switch function executes commands, evaluates block conditions
and evaluates different time supervision conditions. Only if all conditions indicate a switch
operation to be allowed, the function performs the execution command. In case of erroneous
conditions, the function indicates an appropriate "cause" value, see Table 476 .
SXCBR has an operation counter for closing and opening commands. The counter value can be
read remotely from the operator place. The value is reset from local HMI, a binary input or remotely
from the operator place by configuring a signal from the Single Point Generic Control 8 signals
(SPC8GAPC) for example. The health of the external equipment, the switch, can be monitored
according to IEC61850-8-1. The operation counter functionality and the external equipment health
supervision are independent sub-functions of the circuit breaker function.
Local/Remote switch
M13487-7 v4
One binary input signal LR_SWI is included in SXCBR to indicate the local/remote switch position
from switchyard provided via the I/O board. If this signal is set to TRUE it means that change of
position is allowed only from switchyard level. If the signal is set to FALSE it means that command
from IED or higher level is permitted. When the signal is set to TRUE all commands (for change of
position) are rejected, even trip commands from protection functions are rejected. The
functionality of the local/remote switch is described in Figure 445 .
