Fault Reporting BE1-11m
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 33-8 and Table 33-3, call-out B.
Fault Clearing Time
This line reports the time from when the BE1-11m detected the fault until the BE1-11m detected that the
fault had cleared. Refer to Figure 33-8 and Table 33-3, call-out C.
• If the fault report was triggered through the BESTCOMSPlus interface, 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 trigged until the fast current detector function detects that the arc has
been extinguished.
Oscillographic Record
This line reports the number of oscillographic records that are stored in memory for this fault report. Refer
to Figure 33-8 and Table 33-3, call-out E. Recording of oscillographic records is described later in this
chapter.
VA, IA, IA Circuit 2, VB, IB, IB Circuit 2, VC, IC, IC Circuit 2
These lines report the phase voltage and current magnitudes and angles measured two power system
cycles immediately following the trip trigger. If the fault is cleared prior to the BE1-11m tripping, the
recorded fault voltages and currents are for the power system cycle two cycles prior to the end of the
fault. Refer to Figure 33-8 and Table 33-3, call-out F.
V0, V1, V2
These lines report the three-phase residual, positive-sequence, and negative-sequence voltage
magnitudes and angles measured two power system cycles immediately following the trip trigger. If the
fault is cleared prior to the BE1-11m tripping, the recorded fault voltages are for the power system cycle
two cycles prior to the end of the fault. Refer to Figure 33-8 and Table 33-3, call-out F.
IG, IG Circuit 2
This line reports the ground current magnitude and angle measured two power system cycles
immediately following the trip trigger. If the fault is cleared prior to the BE1-11m tripping, the recorded fault
current is for the power system cycle two cycles prior to the end of the fault. Refer to Figure 33-8 and
Table 33-3, call-out F.
3I0, 3I0 Circuit 2, I1, I1 Circuit 2, I2, I2 Circuit 2
These lines report the three-phase residual, positive-sequence, and negative-sequence current
magnitudes and angles measured two power system cycles immediately following the trip trigger. If the
fault is cleared prior to the BE1-11m tripping, the recorded fault currents are for the power system cycle
two cycles prior to the end of the fault. Refer to Figure 33-8 and Table 33-3, call-out F.
FP, FX
This line reports the frequency for the phase voltage input and auxiliary voltage input measured
immediately following the trip trigger. Refer to Figure 33-8 and Table 33-3, call-out F.
