Applications

The capabilities of the BE1-11d make it ideally suited for applications with

the following attributes:

• Isolation between the IT-D and the BE1-11d via fiber optic communications

• The flexibility provided by wide setting ranges, multiple setting groups, and

multiple coordination curves in one unit

• The economy provided by a multifunction unit. This one unit can provide all

of the protection, control, metering, and local and remote indication functions

required for typical applications.

• The small size and limited behind-panel projection facilitates modernizing

protection and control systems in existing equipment

• Coordinated protection with other BE1-11 protection systems on both ac and

dc sides of a rectifier

• High-speed Ethernet communications and protocol support

• The capabilities of a numeric multifunction relay

• IEC 61850 functionality
