B-PRO 4000 Multi-function Bus Protection Relay (3-Phase)

Data Sheet Manual Ordering Template Software Firmware v1.0b Release Description

The B-PRO relay provides bus and substation differential protection (low impedance) with CT saturation security, integrated breaker failure, overcurrent protection and SCADA control in a fully integrated protective relay solution. The B-PRO relay also provides metering, DFR quality fault oscillography, dynamic swing recording and sequence of events logging.

Protection

• 6 sets of CT inputs for differential protection (18 currents) using percentage slope characteristic for security on external faults. Low impedance design allows different CT ratios for each of the 6 inputs
• Backup overcurrent and breaker failure for each input current. User defined directional control of overcurrent functions for networked lines. Apply 3 phase voltages to apply over/under voltage and frequency functions
• Protection functions include IEEE devices 87B, 27, 59, 60, 81, 87T, 50LS, 50BF, 50/51/67, 50N/51N/67, 46/50/51/67
• 1 or 2 separate differential zones - bus and transformer or Bus 1 and Bus 2 for multiple buses
• ProLogic - control logic statements

• High quality recording - fault recording (96 samples/cycle), dynamic swing recording (1 sample/cycle), and event logging (1 ms resolution)
• Metering functions for each input connection

• IEC 61850 Station Bus on dedicated Optical/Copper Ethernet Ports
• Enhanced DNP3 SCADA communication protocol including point lists, class support and multiple master station support
• Modbus SCADA communication protocol
• IRIG-B port (through BNC connector) for precise time stamping and sample synchronization
• Serial communication port
• 30 virtual inputs for local and remote control
• Optional internal modem

• Easy to use, simplified relay setting and record analysis software (Windows® 2000/XP) included
• Intuitive ASCII-terminal interface provides full local or remote access
