Relai Proteksi Multifungsi
B-PRO Bus Protection Relays
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.
B-PRO 4000 Bus Protection Relay (Supports up to 6 bays) B-PRO 4000 Multi-Busbar Protection Scheme (Supports up to 24 bays)
Fitur & Keunggulan
- 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
- 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
- Delta Phase and Rate of Change of Differential (ROCOD) algorithms provide enhanced security during external faults with heavy CT saturation
