Operand description
Same set of operands as shown for BKR FAIL 1
Breaker restrike detected in any phase of the breaker control 1 element
Breaker restrike detected in phase A of the breaker control 1 element
Breaker restrike detected in phase B of the breaker control 1 element
Breaker restrike detected in phase C of the breaker control 1 element
Same set of operands as shown for BKR RESTRIKE 1
Breaker 1 3-pole open command/trip initiated
Breaker 1 close command initiated
Breaker 1 phase A bad status is detected (discrepancy between the 52/a and
52/b contacts)
Breaker 1 phase A intermediate status is detected (transition from one
position to another)
Breaker 1 phase A is closed
Breaker 1 phase A is open
Breaker 1 phase B bad status is detected (discrepancy between the 52/a and
52/b contacts)
Breaker 1 phase B intermediate status is detected (transition from one
position to another)
Breaker 1 phase B is closed
Breaker 1 phase B is open
Breaker 1 phase C bad status is detected (discrepancy between the 52/a and
52/b contacts)
Breaker 1 phase C intermediate status is detected (transition from one
position to another)
Breaker 1 phase C is closed
Breaker 1 phase C is open
Breaker 1 bad status is detected on any pole
Breaker 1 is closed
Breaker 1 is open
Breaker 1 has discrepancy
Breaker 1 trouble alarm
Breaker 1 manual open
Breaker 1 manual close
Breaker 1 trip phase A command
Breaker 1 trip phase B command
Breaker 1 trip phase C command
At least one pole of breaker 1 is open
Only one pole of breaker 1 is open
Breaker 1 is out of service
Breaker 1 tagged so manual trip and close and autoreclose are blocked

Breaker 1 status manually substituted to open
Breaker 1 control interlocking is manually bypassed
Breaker 1 control interlocking is not manually bypassed
Breaker 1 command to manually block autoreclose
Breaker 1 command to manually enable autoreclose
Same set of operands as shown for BREAKER 1
