The B-PRO relays provide low impedance differential protection for any bus bar configuration with CT saturation security, integrated breaker failure, overcurrent protection and SCADA control in a fully integrated solution. The B-PRO also provides control, automation, metering, monitoring, and high quality fault oscillography and sequence of events logging.
Application in B-PRO 4000 Bus Protection Relay
Simple bus applications with up to 6 feeders and 2 differential zones with breaker failure, or 4 feeders and 1 transformer, including separate full transformer differential protection (87T)
1 or 2 separate differential zones - bus and transformer or Bus 1 and Bus 2 for multiple buses
Application in Multi-Busbar Protection Scheme
Applications for bus configurations for up to 24 feeders Protection for 3 differential zones and a check zone.
Scalable architecture allows flexibility to use the most cost effective hardware combinations, based on the actual number of zones and number of current inputs in the bus system
Dynamic zone selection (including fixed zones) and Selective Bus Tripping based on Isolator status
