Fault Recording
Enhanced model BE1-BPR relays can also be configured to record and save digital fault data for all three
phases plus neutral (0 to 200 amperes) and the digital state of each input and output contact. Analog
waveforms are digitized by sampling the waveforms at a periodic rate and converting the measured
signals to digital values. When a fault occurs, the digital data is stored as a fault record. Multiple fault
records can be stored and recalled through the serial port by an operator. To display the fault waveform
for analysis, recalled data can be imported into a data base file and converted into a graph. Standard
programs that read and display ASCII data (in accordance with IEEE Standard Common Format for
Transient Data Exchange (COMTRADE) for Power Systems) can also be used. BESTView application
software provides a simple terminal interface to communicate with the relay, retrieve and display
COMTRADE oscillographic fault data, and provide a remote front panel interface. This software is not
required to communicate with the relay. However, it combines the functions of a number of separate
packages into one program that is optimized for the BE1-BPR relay. To order this software free of charge,
contact the Customer Service Department of the Power Systems Group, Basler Electric, and request the
BESTView Software Package.
MODEL NUMBERS
Tables 1-1 and 1-2 provide information for the nominal current input to the current transformers, part
number, options, mounting style, and operating power supply voltage. Standard BE1-BPR relays do not
have oscillography, fault records, contact duty logs, or two calibration levels (current metering is limited to
10 amperes).
