Notes for Table 5-4:
1. All current values are in primary centiamps (value 1 represents 0.01 ampere). When SEF, neutral
current (value 1 represents 0.0001 ampere).
1∗. Current analog input point generates an analog event if the current value is bigger than the
“previous current value plus dead band”, or smaller than the “previous current value minus dead
band”.
Dead band for an analog event is configurable via DNP Analog Output point 23, “Current Dead
band”. The default value for the dead band is set to be ±2.5% of the primary nominal current. For
more information about dead band configuration, see the description in the following paragraphs
Analog Output Status Points and Control Blocks, point 23, Note 14 for Table 5-12.
2. Fault Number range is from 1 to 255. For example, after 255, fault number is going to be 1.
3. This time is a fault trigger time presented in relay’s internal format: part 1 contains days (1 to
65535), and part 2 contains milliseconds (1 to 86,400,000) since January 1, 1984. This time is
equal to the time of Binary Input Event “New Fault triggered” (transition from 0 to 1).
Notice that the Binary Input Event time stamp is presented in DNP time stamp format, since
January 1, 1970.
4. Active setting group at time of fault (0 or 1 or 2 or 3).
5. Event type (value is 1, 2, 4, 8, or 16) reports the classification assigned to the fault event. Fault
events are classified into five categories.
a.
Breaker Failure (Event Type value is 1): A fault was initiated by the pickup expression and
the breaker failure trip became true before fault was cleared.
b.
Trip (Event Type value is 2): A fault was initiated by overcurrent pickup and the relay tripped
to clear the fault.
c.
Logic (Event Type value is 4): A fault was detected as defined by the relay logic trigger
expression, but no fault was detected as defined by the pickup expression.
d.
Pickup (Event Type value is 8): A fault was initiated by the pickup expression but the relay
never tripped indicating that the fault was cleared by some other device.
e.
RF=TRIG (Event Type value is 16): A Fault was triggered by the ASCII command
RF=TRIGGER received via the front panel communication Serial Port or rear RS-232 port.
6. Targets-part 1 and targets-part 2 are bit-mapped variables that report what targets were logged to
the fault report between the time that the trip expression became true until the end of the fault. See
Table 5-5 for the target format.
