Fault Date and Time. These lines report the date and time of the initial trigger of the event. This is based
on either the pickup logic expression or the logic trigger expression becoming TRUE as defined by the
SG-TRIGGER command. Refer to
Figure 6-6 and Table 6-8, call-out A.
Fault Trigger. This line reports the logic variables in the pickup or logic trigger expressions that became
TRUE to trigger the recording of the event.
Active Group. This line reports what setting group was active at the time that the fault occurred.
Recloser State. This line reports the state of the recloser shot counter prior to the fault that triggered the
report.
Fault Type. This line reports the faulted circuit such as phase-phase, phase-ground, etc.
Targets. This line reports the targets that were logged to the fault report between the time that the trip
expression became TRUE until the end of the fault. Refer to
Figure 6-6 and Table 6-8, call-out B.
Distance to Fault. This line reports the distance to the fault on the line. Units are the same as the units
used to determine line length in SG-Line settings. Refer to
Figure 6-6 and Table 6-8, call-out F.
Fault Clearing Time. This line reports the time from when the relay detected the fault until the relay
detected that the fault had cleared. Refer to
Figure 6-6 and Table 6-8, call-out C.
If the fault report was triggered by the RF-TRIG command, the recording of the report was terminated
after 60 seconds and this line is reported as N/A.
If the pickup or logic expressions stay TRUE for more than 60 seconds, an alarm bit in the programmable
alarm function is set and this line is reported as N/A. In this situation, the fault reporting functions
(including targets) won't operate again until the pickup and logic trigger expressions return to a FALSE
state to enable another trigger.
Breaker Operate Time. This line reports the breaker trip time from the breaker monitoring and alarm
function. This is the time measured from when the breaker is tripped until the fast-dropout current
detector function detects that the arc has been extinguished. Refer to
Figure 6-6 and Table 6-8, call-out
D.
Oscillographic Reports. This line reports the number of oscillographic records that are stored in memory
for this fault report. Refer to
Figure 6-6 and Table 6-8; call-out E. Recording of oscillographic records is
described in the Oscillographic Records subsection.
IA, IB, IC, IG, IQ. These lines report the current magnitudes and angles measured two power system
cycles immediately following the trip trigger. If the fault is cleared prior to the relay tripping, the recorded
fault currents are for the power system cycle two cycles prior to the end of the fault. Refer to
Figure 6-6
and
Table 6-8, call-out F.
VA, VB, VC, VX. These lines report the voltage magnitudes and angles measured two power system
cycles immediately following the trip trigger. If the fault is cleared prior to the relay tripping, the recorded
fault voltages are for the power system cycle two cycles prior to the end of the fault. Refer to
Figure 6-6
and
Table 6-8, call-out F.
FP and FX. This line reports the frequency for the phase voltage input and auxiliary voltage input
measured immediately following the trip trigger. Refer to
Figure 6-6 and Table 6-8, call-out F.
Retrieving Fault Report Information from the Relay
Fault Summary Directory Report. The fault reporting function provides a directory of fault summary
reports that lists the number assigned to the fault summary report along with the date and time of the
fault, the event type, and the total number of oscillography records stored in memory for that event. The
event number is important because it is required to retrieve information about that event from the relay.
This directory report can be accessed by using the RF command.
RF Command
Purpose: Read or reset fault report data.
Syntax: RF-<n/NEW>=<0/TRIG>
Comments: n = fault record number (1 to 255)
NEW = newest fault record since all records were last reset using RG=0
RF Command Example:
Example 1. >RF
