Figure 106: Arc protection
The optional autoreclosing function is configured to be initiated by operate 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. This signal is not connected in the configuration.
The open command from the autorecloser is directly connected to binary output
X100:PO3, whereas close command is connected directly to binary output X100:PO1.
Set the parameters for DARREC1 properly.
Check the initialization signals of the DARREC1.
