ASCII Command Reference
Command Description
BNAME
The BNA command produces ASCII names of all relay Fast Meter status bits in a
Compressed ASCII format. See SEL Protocol on page 15.23 for more informa-
tion on Fast Meter and the Compressed ASCII command set.
BREAKER
NOTE: Not all SEL-400 series relays
support breaker monitoring.
Use the BREAKER command to display circuit breaker reports and the circuit
breaker history reports. You can also preload accumulated breaker monitor data.
The BRE command also resets the circuit breaker monitor data. To use the BRE
command, you must enable the circuit breaker monitors for the circuit breakers
of interest. See Circuit Breaker Monitor on page 8.1 for more information.
