REF542plus success story

„ Market launch 2000

„ Delivered units approx. 50,000

„ Applications ranging from low voltage to high voltage

„ In service worldwide

„ Many different protection and control functions

Event recording

All events are stored with a resolution of 1 ms in the central unit and in the BUs.

System, protection and test events can be generated.

Protection events refer to the protected busbar and include the changes in the disconnector and breaker positions,

trips, etc. Test events are recorded during testing with the test signal generator.

System events describe the diagnostic and fault messages of the NBP system as a whole.

Product features

• Motor protection with voltage- and frequency-based protection and measurement functionality

• Motor protection both during motor start-up and normal run, with protection and fault clearance in abnormal situations as well

• Optional arc protection and high-speed outputs

• Supports IEC 61850 Editions 1 and 2, including HSR and PRP, GOOSE messaging and IEC 61850-9-2 LE for less wiring and supervised communication

• IEEE 1588 V2 for high-accuracy time synchronization and maximum benefit of substation-level Ethernet communication

• Supports Modbus, DNP3 and IEC 60870-5-103 communication protocols

REM615 is a dedicated motor protection and control relay designed for the protection, control, 

measurement and supervision of induction motors in manufacturing and process industry. 

REM615 is a member of ABB’s Relion® product family and part of its 615 protection and control product series. 

The 615 series relays are characterized by their compactness and withdrawable-unit design. 

Re-engineered from the ground up, the 615 series has been designed to unleash the full potential of the 

IEC 61850 standard for communication and interoperability between substation automation devices.

Once the standard configuration relay has been given the application-specific settings, it can directly be put into service.

Product benefits

• Compact and versatile solution for utility and industrial power distribution systems with integration of protection, control, monitoring and supervision in one relay

• Motor protection with motor start-up and loss of load supervision as well as thermal overload,

  motor load jam and phase-reversal protection, either with sensors or conventional instrument transformers

• Ready-made standard configurations for fast and easy setup with tailoring capabilities

• Withdrawable plug-in unit design for swift installation and testing

• Large graphical display showing customizable SLDs, accessible either locally or through an easy-to-use web-browser-based HMI

• Extensive life-cycle services

Disturbance recorder function

The three conductor currents, the current in the directly earthed conductor,

binary signals, and the voltages, can be recorded in each BU. 

Recording can be started, for example, by a protection function or an input signal. 

The disturbance recorder data are stored in the REB 500. 

They can be read out directly on the BU or at the central unit in COMTRADE format and stored on the PC. 

An evaluation program (eg, WINEVE) is used for further processing.

REF542plus Multifunction Protection and Switchbay Control Unit integrates all the secondary functions in a single unit. 

This multifunctional unit also features a selfmonitoring function. 

All functions are designed as freely configurable software modules. 

Therefore, a wide range of operation requirements in MV stations can be met without any problems. 

The versatility of the software makes it possible to use the REF542plus on every 

switchboard independent on the specific application required.

Overcurrent-time protection

This is a back-up protection function which is calculated locally in the BU and used to provide simple,

autonomous feeder protection in each BU.
