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 (Optional). 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 6-6, call-out B.
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 6-6, 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) will not 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 6-6, 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 6-6, call-out E. Recording of oscillographic records is
described in the Oscillographic Records subsection.
IA, IB, IC, IG (BE1-700C). 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 6-6, call-out F.
VA, VB, VC, VX (BE1-700V). 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 6-6, call-out F.
FP and FX (BE1-700V). 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 6-6, 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.
New Faults Counter. One line of the fault summary directory report contains the new faults counter. The
new faults counter tracks how many new fault reports have been recorded since the new faults counter
was reset to 0. This counter provides a way to check the fault information and then reset the new faults
counter. Then, the next time that the relay is checked, it's easy to determine if any fault reports have been
entered. Resetting the new faults counter is achieved using the RF-NEW=0 command. Write access to
Reports must be gained to reset the new faults counter through the communication ports. The new faults
counter can also be viewed at HMI Screen 4.1. The new faults counter cannot be reset at the HMI.
Fault Summary Reports. Individual fault summary reports can be retrieved using the RF-n command,
where n represents the number assigned to the fault summary report. To obtain the most recent report,
use RF-NEW. If additional detail is desired, Sequence of Events Recorder data and Oscillographic data
can be obtained for the faults also. This is discussed in detail later in this section.
Oscillographic Records
Recording Oscillographic Records
The fault reporting function can record up to 16, IEEE Standard Common Format for Transient Data
Exchange (COMTRADE) oscillographic records. Each time the fault reporting function starts recording a
