REU615 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.
REU615 is a member of ABB’s Relion® product family and part of its 615 protection and control series of relays.
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
