Bus Protection System

March 27, 2012
Distributed bus protection simplifies field wiring through flexible mounting and simple expansion capabilities.

The Multilin B95Plus Bus Protection system for protection of large power system buses is the first large bus protection relay to use the Multilin HardFiber Brick IEC 61850 process bus merging unit in a distributed bus protection architecture. It reduces the time and cost required for design, installation and commissioning of field wiring between the primary equipment and the control room for bus protection systems. Field wiring is terminated directly at the brick installed on primary equipment. A connectorized fiber optic cable between the brick and the protection system is the only wiring across the switchyard. For new installations, this allows utilities to transfer the work of designing, installing and commissioning field wiring for new installations to primary equipment suppliers as they install bricks during their manufacturing process.
