u  Overview

The BR-10R/RN control is installed in combination with the recloser on MV overhead distribution lines. It is an integrated control device that performs various functions such as status monitoring and measurement of electrical quantities of distribution line, fault detection and line protection, status monitoring of the connected equipment, battery management, and communication for remote control.

u  Key Features

•     Directional phase and ground overcurrent, negative sequence overcurrent, and SEF protections

•     High current trip and lockout

•     45 built-in TCC curves, and reclose sequence that can be set up to three reclose

•     Four protective setting groups with alternate settings according to power flow direction

•     Hot line tag and single shot protection

•     Inrush restraint and cold load pickup scheme

•     Over/under voltage and frequency protection

•     Detection and protection for broken conductors and loss of phase

•     Calculation of remaining VI contact life and VT failure detection

•     Fault locator, and automatic loop control scheme that does not require communication

•       Power quality and line status monitoring, electrical quantity measurement, and status monitoring of related devices in real time

•     Battery management and automatic battery test

•     Various events and fault waveforms record

•     Operating program for setting and verifying parameters, checking status and history data, and downloading firmware

•     External indicator to check main conditions from the ground

•     Four-digit password security to access the controls

•     Drive module to operate the magnetic actuator built into the recloser and two capacitor banks

•     DNP3 and IEC 60870-5-101/104 protocol over serial or Ethernet

•     Electrically isolated RS 232 and RS 485 ports, and Ethernet portfor connection with distribution automation system

•     Status monitoring and remote control via SMS

•     Optional GPS and Bluetooth interface

•     Auxiliary DI and DO contacts, terminal block, and indicators that can be used according to user‘s purpose

u  Applications

•     Used as a traditional recloser control installed on distribution lines or in substations to protect distribution lines

•     Used as a recloser control to integrate reclosers into distribution automation systems

•       Used as a recloser control for lines to which multiple sources are connected, including distributed energy resources

•     Used as a recloser control in systems requiring automatic loop control scheme

•     Used as a control for the recloser or circuit breaker in systems requiring load shedding to maintain power quality of distribution lines

•     Used as a control for the fault interrupters that are installed on customer service lines or branch lines
