1 Overview
The B-PRO (model 8700/BUS) is a microprocessor-based relay providing bus
differential protection, integrated breaker failure and overcurrent protection
functions, metering, fault and swing oscillography.
B-PRO has two working modes—online and offline. In the online mode you
can use any communication software package (e.g. Procomm or HyperTermi-
nal) to connect to the B-PRO using VT100 terminal emulation. In online mode
you can:
• change and review relay settings
• view event and metering information
• initiate and retrieve recordings, and retrieve settings
In offline mode you can use
Offliner
Settings and RecordBase View software
to:
• create and review relay settings
• analyze fault waveforms
• store records
The B-PRO relay provides differential protection (low-impedance) for the fol-
lowing types of bus configurations:
• 1 bus with up to six inputs and one set of voltage inputs (Figure ).
• 1 transformer zone with 2 inputs.
• 2 differential zones, 1 for a bus and 1 for a transformer (Figure ).
• 2 bus zones (Figure 1.3).
Backup feeder protection is provided for all inputs, regardless of which zone is
selected, even if an input is not used in a differential zone.
