BE1-11 m Fault Reporting
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 BE1-11 m 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.
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.
• Thermal Capacity. This line reports the thermal capacity of the motor.
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 BE1-11 m 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 Error! Reference source not found. for
Oscillographic Records Settings.
All channels are recorded (IA, IA Circuit 2, IB, IB Circuit 2, IC, IC Circuit 2, IG, IG Circuit 2, VA, VB, VC,
VX, FP, FX, Analog Inputs, RTDs, and Thermal Capacity) as they happen in real time.
A settings snapshot is taken and recorded with each event. This snapshot will be stored in a file that can
later be uploaded to the device to return it to the settings that were active at the time of the recording.
BE1-11
m protection systems have three identification fields: Device ID, Station ID, and User ID. These
fields are used in the header information lines of the oscillographic records. Refer to the BESTCOMSPlus
Software chapter for information on BE1-11
m
identification settings.
Oscillographic Records Settings
The oscillographic records settings are programmed through BESTCOMS Plus . Use the Settings Explorer
to open the Metering Configuration, Fault Records screen as shown in Figure 33-7. Enter the values for
Sample Resolution, Number of Records to Store, and Prefault Cycles.
