Hitachi Energy announced the launch of its Relion REF650 multi-application protection and control relay, specifically designed for medium-voltage power distribution grids. The REF650 is designed to help enhance flexibility, modularity, security, and a new, intuitive user interface help to make it better suited for the evolving power quality requirements across both utility and industrial operations.
With the growing complexity and increased digitalization of the distribution grid, electrical substations should be managed with higher fidelity. System components, such as protection and control relays, help to integrate critical data sources to operate distribution grids more autonomously and responsively.
Distribution operators prefer technologies, products and solutions that can work together as a modular, scalable, and intelligent platform across the network. They also require compliance with the latest standards and full interoperability across diverse equipment and power sources. The REF650 is an additional Hitachi Energy solution for power automation and communication. The company is delivering technology that serves over 50 percent of global utilities.
REF650 offers new features and benefits for the protection and control of primary distribution systems in key areas:
Cost-efficiency: single-device modular design is suited for long-term deployment with scalable and flexible features
Ease of use: new Human Machine Interface (HMI) touchscreen shows machine status and real-time voltage/current data while providing an operator with interactive control
Performance and interoperability: REF650 is certified to industry standards (IEC 61850 Ed 2.1), with PCM600 3.1, compatible across vendors
Simplified engineering: more streamlined configuration and parameterization allow for easier setting changes, helping to simplify testing and maintenance processes
Compact form factor: a smaller size reduces the space needed for installation, especially in space-constrained environments
Sustainable, safer, and more secure: provides increased uptime with modular, user exchangeable hardware modules, and supports extended operating temperature ranges and vibration classes
After-sales service: can be reconfigured and extended with hardware modules, offering greater flexibility in incorporating late project or design changes
Hitachi Energy’s Grid Automation portfolio helps to enable customers to manage the evolving demands of utility grids by delivering additional visibility and scalable communications solutions for increased performance, safety, and cost efficiency. The company also delivers additional services and digital capabilities, including integration of IT/OT, data analytics, and digitalization tools to make grid systems more sustainable, flexible, and secure.
