Features

The BE1-11d protection system includes many features for the protection,

monitoring, and control of dc switchgear. These features include protection

and control functions, metering functions, and reporting and alarm functions.

A highly flexible programmable logic system called BESTlogic™Plus allows

the user to apply the available functions with complete flexibility and

customize the system to meet the requirements of the protected dc switchgear.

Programmable I/O, extensive communication features, and an advanced user

interface provide easy access to the features provided.

The following information summarizes the capabilities of this multifunction

device. Each feature, along with its setup and use, is described in detail in

the later chapters of this manual.

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

Introduction

The BE1-11d DC Power Protection System provides flexible, reliable, and

economical dc power protection, control, monitoring, and measurement

functions. The capabilities of the BE1-11d make it well suited to provide

comprehensive dc power protection. The BE1-11d offers dc overcurrent,

over/undervoltage, rate of rise, power, and thermal overload protection

functions as well as breaker reclosing and RTD (Resistance Temperature

Detector) inputs with remote module. It offers breaker and trip-circuit

monitoring, and oscillography and sequential events recording.

Control features include virtual selector switches, circuit breaker control,

virtual lockout, and variable-mode timers. System metering and status

information are available at the BE1-11d front panel and through the

BE1-11d communication ports. The system is suitable for mounting in

OEM cubicle or retrofit switchgear applications.

A front-panel USB port or optional rear Ethernet port enables local

communication between the BE1-11d and a PC operating with

BESTCOMSPlus® software. BESTCOMSPlus software simplifies the

commissioning process by providing a graphical interface for setting

the BE1-11d and configuring a protection and control scheme for your

application. Through BESTCOMSPlus, all BE1-11d settings and logic can

be retained in a file for printing or uploading to other BE1-11d protection

systems. Oscillography and sequential events records can be retrieved

from a BE1-11d, viewed, and printed.

Front-panel features include a large, backlit alphanumeric display and LED

indicators that display system parameters, BE1-11d settings, and BE1-11d

status. Pushbuttons enable navigation through the display menu, changes

to settings, resetting of targets (with password access), and direct access

to virtual switches.

Up to two IT-D Isolation Transducers can be used with each BE-11d DC

Power Protection System. An IT-D transducer electrically isolates the

BE1-11d from power parameters monitored by the system.

Each IT-D can monitor two parameters. Parameters monitored by the

IT-D include DC system voltages and current (measured through a

metering shunt). The output of each IT-D channel is a pulsed digital signal

with a frequency that is proportional to the monitored input signal.

These fiber optic channel outputs are provided to the BE1-11d DC Power

Protection System.

Two 30-foot fiber optic cables with fiber optic connectors are supplied with

every IT-D module ordered.

Rugged and Flexible Construction

A rugged, compact metal case provides improved electromagnetic compatibility and

make the RDP-110C resistant to moisture, salt fog, dust, dirt, and chemical

contaminants. Two available mounting configurations provide the option of semi-flush

mounting or surface (projection) mounting. Conduit knockouts on the case enable

the RDP-110C to be used as a “pass-through” or junction box for other site wiring.

Simple Connections

RDP-110C connections consist of control power wiring and wiring for communication

between the DGC and RDP 110C. Two-wire, RS-485 communication between the

RDP-110C and DGC simplifies wiring and ensures electrical noise immunity over long

distances.
