B90—Bus Differential System


     

KEY BENEFITS

>High-speed protection algorithm for enhanced stability with trip times of 0.75 power cycle

>Superior CT saturation detector capable of detecting CT saturation even with only 2 msec of saturation free current for enhanced through fault stability

>Suitable for different bus configurations, scalable architecture to protect up to 24 feeders

>Pre-engineered bus protection system: use experienced GE Digital Energy application engineers to develop busbar protection system for your specific configurations

>Three independent fiber or copper Ethernet ports for simultaneous/ dedicated network connections with advanced 1 microsecond time-synchronization via LAN with IEEE® 1588 support

>Use high-speed communications to reduce wiring and installation costs, exchange inputs and outputs between relays to achieve relay-to-relay interaction

>Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control

>Increase network availability by reducing failover time to zero through IEC® 62439-3 "PRP" support

>CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP, AAA, Radius, RBAC, Syslog)

APPLICATIONS
>Re-configurable multi-section busbar with up to 24 feeders

>Single bus, breaker-and-a-half bus bar configurations, double bus and triple bus with and without bus couplers
