Voltage RelayREU 6101MRS 756026ApplicationDesignREU 610 is a versatile multifunction voltagerelay which is used in general voltage supervision applications. It complements the rangeof feeder protection relay REF 610 and motorprotection relay REM 610 in industrial outgoing feeder and motor feeder applications. Therelay can also be used as back-up protectionfor industrial as well as utility applications.The large number of integrated protectionfunctions, including two overcurrent protection elements, two undervoltage protectionelements and two residual overvoltage protection elements, makes the relay a completeprotection against various voltage fault conditions.REU 610 is based on a microprocessor environment. A self-supervision system continuously monitors the operation of the relay.Auxiliary voltageThe HMI includes a Liquid Crystal Display(LCD) which makes the local use of the relaysafe and easy.Local control of the relay via serial communication can be carried out with a computerconnected to the front communication port.Remote control can be carried out via the rearconnector connected to the control and monitoring system through the serial communication bus.ProtectionfunctionsThe large number of digital inputs and outputcontacts allows a wide range of applications.REU 610 requires a secured auxiliary voltagesupply to operate. The internal power supplyof the relay forms the voltages required bythe relay electronics. The power supply is agalvanically isolated (flyback-type) DC/DCconverter. When the auxiliary voltage is connected, the green indicator LED (ready) onthe front panel will be on. For detailed information on power supply, refer to table 2.The primary side of the power supply is protected with a fuse located on the PCB of therelay.symbols and ANSI device numbersFunction description4IEC symbolIEEE device numberOvervoltage protection, low-set stageU 59P-1Overvoltage protection, high-set stageU 59P-2Negative phase-sequence overvoltage protectionU2 47Undervoltage protection, low-set stageU 27P-1Undervoltage protection, lhigh-set stageU 27P-2Positive phase-sequence undervoltage protectionU1 27DResidual overvoltage protection, low-set stageU0 59N-1Residual overvoltage protection, high-set stageU0 59N-2Circuit-breaker failure protectionCBFPCBFAILLockout relay-86
