Description

ABB REU615 IEC Voltage protection and control numerical relay

ABB VOLTAGE PROTECTION AND CONTROL REU615 IEC NUMERICAL RELAY COMPACT AND VERSATILE SOLUTION FOR UTILITY AND INDUSTRIAL POWER DISTRIBUTION SYSTEMS

ABB REU615 IEC relay is a voltage protection and control relay for voltage and frequency-based protection in utility and industrial power distribution systems, including networks with distributed power generation. REU615 is also ideal for voltage regulation.

Scope

Voltage and frequency protection as well as automatic voltage regulation of power transformers with a motor-driven on-load tap changer

Product features

• Exclusively designed for automatic and manual voltage regulation, or alternatively for busbar under voltage and overvoltage supervision, load shedding and restoration
• Ready-made standard configurations for fast and easy setup with tailoring capabilities
• Withdrawable plug-in unit 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

Product benefits

• Extensive range of protection and control functionality for busbar voltage supervision, load shedding and restoration, including over frequency and under frequency protection for power generators and other AC equipment
• Automatic voltage regulation of power transformers with a motor-driven on-load tap changer
• Optional arc protection and high-speed outputs (not with automatic voltage regulator)
• 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

ABB delivers a full range of genuine IEC 61850 protection and control products also including network automation. ABB’s IEC 61850 compliant solutions offer a unified user experience for operating power distribution systems from the secondary substation level up to the network control center level. ABB distribution automation products are built to withstand the rigors of the most demanding environments including marine and offshore, industrial facilities such as mines and paper and petrochemical plants, as well as utilities in urban and rural locations.
