o 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 142 and Table 78, 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 BE1-11g 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 142 and Table 78,
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 BE1-11g tripping, the recorded fault voltages are for the
power system cycle two cycles prior to the end of the fault. Refer to Figure 142 and Table 78, 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 BE1-11g tripping,
the recorded fault current is for the power system cycle two cycles prior to the end of the fault. Refer
to Figure 142 and Table 78, 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 BE1-11g tripping, the
recorded fault currents are for the power system cycle two cycles prior to the end of the fault. Refer to
Figure 142 and Table 78, 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 142 and Table 78, call-out F.
•
VX. This line reports the auxiliary voltage magnitude and angle measured two power system cycles
immediately following the trip trigger. If the fault is cleared prior to the BE1-11g tripping, the recorded
fault voltages are for the power system cycle two cycles prior to the end of the fault. Refer to
Figure 142 and Table 78, call-out F.
•
RTD. These lines report the values of the RTDs when an optional remote RTD module is connected.
•
Analog Inputs. These lines report the values of the analog inputs when an optional remote RTD
module is connected.
Oscillographic Records
Recording Oscillographic Records
Each time the fault reporting function starts recording a fault summary report, it freezes a user-defined
cycle pre-fault buffer. If the fault is not cleared within that time, the fault reporting function records a
second oscillographic record. This second record captures the end of the fault. Oscillographic records are
stored in nonvolatile memory. As additional faults are recorded, the oldest records are overwritten. The
fault reporting function can record up to 32 oscillographic records based on IEEE Std C37.111-1999 -
IEEE Standard Common Format for Transient Data Exchange (COMTRADE) for Power Systems. The
number of records to store is selectable by the user. Maximum data capture resolution is 32 samples per
cycle and is user selectable. The BE1-11g can store up to 2,048 cycles of data at 8 samples per cycle or
512 cycles of data at 32 samples per cycle. Refer to Table 76 for Oscillographic Records Settings.
