ABB introduces a new high-speed substation busbar protection system for utility and industrial power systems using reverse interlocking.  The busbar protection application is based on the company's REF615 feeder protection relay with native support for the IEC 61850 standard and its GOOSE services. This smart grid-enabled relay offers a platform to advance the performance, reliability and cost effectiveness of the power systems of tomorrow and beyond.
Compared with traditional hard-wired inter-relay signaling, relay-to-relay communication over a switched
Ethernet LAN offers an advanced and versatile platform for protection, software-based configuration, continuous supervision of the integrity of the protection and communication system, and inherent flexibility for reconfiguration.
