The circuit breaker closing is enabled when the ENA_CLOSE input is activated. The
input can be activated by the configuration logic, which is a combination of the
disconnector or circuit breaker truck and earth-switch position status, status of the trip
logics and remote feeder position indication. Master trip logic, disconnector and
earth-switch statuses are local feeder ready information to be sent for the remote end.
The OKPOS output from DCSXSWI defines if the disconnector or circuit breaker
truck is either open (in test position) or close (in service position). This, together with
the open earth-switch and non-active trip signals, activates the close-enable signal to
the circuit breaker control function block. The open operation for circuit breaker is
always enabled.
If REMOTE_FEEDER_READY information is missing, for
example, in case of protection communication not connected, it
disables the circuit breaker closing in the local protection relay.
