IEC protection relay REU615

over-voltageunder-voltagefor transformers

Compact and versatile solution for utility and industrial power distribution systems 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. 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
