Figure 122: Arc protection
The optional autoreclosing function is configured to be initiated by trip signals from a
number of protection stages through the INIT_1...5 inputs. It is possible to create
individual autoreclose sequences for each input.
The autoreclosing function can be inhibited with the INHIBIT_RECL input. By default,
few selected protection function operations are connected to this input. A control
command to the circuit breaker, either local or remote, also blocks the autoreclosing
function via the CBXCBR1-SELECTED signal.
The circuit breaker availability for the autoreclosing sequence is expressed with the
CB_READY input in DARREC1_79. The signal, and other required signals, are connected
to the CB spring charged binary inputs in this configuration. The open command from the
autorecloser is connected directly to binary output X100:PO3, whereas the close
command is connected directly to the binary output X100:PO2.
Set the parameters for DARREC1_79 properly.
